1.5 KEEP MACHINE CLEAN

 If water gets into the electrical system, it is

likely to cause malfunctions or misoperation or
electrical leakage. Do not use water or steam
to wash electrical parts (sensor, alternator, start
motor, voltage changer, contactor and circuit
breaker etc.).
 If inspection and maintenance is carried out
when the machine is still dirty with mud or oil,
there is a hazard that you will slip and fall, or
that dirt or mud will get into your eyes. Always
keep the machine clean.

1.6 KEEP OPERATOR’S COMPARTMENT CLEAN

 Do not leave parts or tools lying around the

operator’s compartment.
 Do not use cellular telephones inside the
operator’s compartment when driving or
operating the machine.

 Always face the machine when you use the

steps and hand-holds to enter or leave machine.
 Never use any control lever as hand-hold.
 Never enter or leave machine when the
machine travels, swings, or digs (lifts).

1.8 MOVE MACHINE SAFELY

 While pile driver is moving or rotating,

prohibit anyone from staying within the range
of movement or under the counterweight.
 While machine moves from soft field to hard
field, the machine should moves at
longitudinal direction and face forward, i.e.
main machine operator faces to the front of
panel.
 Prohibit the machine moving at transverse
direction when it moves from soft field to hard
7
 ZYJ680B－ⅡOperator’s Manual

field.
 When short ship slideway rotates or moves
transversely, assure not to collide with long
ship slideway.
 When controlling longitudinal motion, handles
should be operated at the same time and the
same direction. Any separate and
contra-directional operation should be
prohibited. If one of the longitudinal motion
hydraulic cylinders has extended to the
required position, the other must stop at once
to prevent the damage to the main body.
 Keep the main body horizontal in the
procession of vertical motion in case that these
four vertical motion hydraulic cylinders extend
differently (difference should be less than
100mm), which will cause serious damage to
the main body. It is prohibited to operate two
diagonally placed vertical motion cylinders at
the same time.

1.9 REQUIREMENT TO THE CONSTRUCTION FIELD

 Check and assure the construction field meets

the pressure ratio requirement. There should
not be sharp or hard object of small area in
construction field or small protrusion that
would block the pile driver’s motion。
 The gradient of construction field should not
be larger than 3°. If the construction field has
gradient, pile driver should be placed parallel
or vertical to the construction field’s
descending direction
 If construction field can not meet the
requirement for piling, clear up the
construction field until the requirement is met,
then start piling. In the case of old city
rebuilding, especially when there are a lot of
small bricks or stones in the ground, clear the
work site effectively.

1.10 CHECK MACHINE BEFORE START-UP

Before starting machine every day or every

shift, check the machine according to the contents
in “§4.2 preparation before start-up” of this
manual.

1.11 OPERATE SAFELY

 Keep all the non-workers away from working

8
 ZYJ680B－ⅡOperator’s Manual

range.
 Before piling, enough counterweight should be
loaded; during piling, max hydraulic pressure
should not exceed the rated pressure. Otherwise
the pile driver would be lifted off ground.
 The main machine operator and crane operator
should keep good communication and
observation for each other. Prohibit operating
crane or hoisting objects while the machine
moves or rotates. And also, prohibit the machine
moving or rotating while crane is in operation or
hoisting objects.
 Ensure firm binding while hoisting pile.
 Crane’s winch wire should wrap around the
drum for at least 4 circles.
 When lifting pile, it is prohibited to stand in the
working range of crane.
 Check winch wire and pile lifting wire often and
replace them if any damage occurs.
 Check and screw down the connection bolts at
the crane slewing support every 2 months, the
screwing down torque is 560-600NM. Replace
them with original SUNWARD bolts if any
abnormality occurs.
 Lift rated weight within the limitation of jib
lifting angle to avoid crane jib overloading.
 Before pressing piles, make sure the hook has
been separated from the tools for lifting pile. If
not, there will be serious accident of the lifter
and pile driver. In some special condition, if the Figure 1-10
crane winch has to be used as pile follower, the
speed of pile follower must be higher than the
speed of piling.
 Operators shouldn’t put their arms and legs into
the gaps between the pile pressing platform and
the main body.
 Prohibit any person from standing under the
counterweight during piling.
 Prohibit pushing any handles in the process of
jointing piles in case that piles fall down to hurt
any people.
 When stop operating, let the short ship slideway
fully touch ground and the long ship slideway
touch ground a little. Then lay the clamping box
to the bottom on the support beam, shut down
power and lock the door.

2 BRIEF INTRODUCTION TO SUNWARD SERIES PILE DRIVER

SUNWARD Intelligent Equipment Co. Ltd, combining production, teaching and research, is a
new-type enterprise. SUNWARD series hydraulic static press-in pile drives are new kinds of
machine of high efficiency and energy saving.
WORK PRINCIPLE:
In the process of pile pressing, the machine’s weight acts as reaction force to balance the friction
drag from beside the pile and the reaction force from the pile tip, then the pile is pressed in the
ground.

2.1 ADVANTAGES OF SUNWARD PILE DRIVER

The method of using static press-in precast pile is a very particular way of pile foundation
construction. The precast pile is completely pressed into ground by static force. With development
of pile machinery and enhancement of environment-protecting requirement，it has become a
promising way of pile foundation. Compared with other pile foundation construction methods like
impact, vibration or cast, this way has the following advantages:
1. ENVIRONMENT FRIENDLINISS ----The work of construction is quiet and neat, and workers
have less work intension. It’s suitable for urban construction because of the absence of noise,
vibrancy and pollution.
2. HIGH EFFICIENCY ---- Its efficiency is much higher than that of other pile drivers, and it can
finish hundreds meters of pile foundation in a day work (8 hours). It is most suitable for urgent
and large foundation projects.
3. HIGH QUALITY ---- The process of driving pile is similar to testing pile, therefore the rate of
success is almost 100%.
4. UNLIMITED TOTAL LENGTH OF JOINTED PILE ---- The total length of jointed piles is not
limited if pile’s strength allows.
5. LOW COST ---- In all kinds of pile foundation construction methods, the cost of static press-in
technics is one of the most economical types if compared by the cost of carrying capacity per
cubic meter of pile.(equals to that of casting pile when carrying capacity is the same)

2.2 COMPARED WITH THOSE BY OTHER FACTORIES

Customers can choose suitable type according to their practical needs in the range of pressing
force from 800～12000 KN. Compared with pile driver made by other factories, SUNWARD
series have the following prominent advantages:
ⅠTECHNIQUE INOVATIONS
In the series products, Sunward has one patent for invention(ZL 93110671.0), three new type
practical patents (patent No. ZL 95236709.2、ZL99249764.7、ZL 99249765.5. These patents got
National Excellence Award and the Ten Most Well Applied Patents Award in Hunan province.
Adopting patent technology highly improves performance of Sunward pile driver:
1. The quasi-constant-power pile driving system is composed of two pairs of hydraulic cylinders
which work orderly in pile-driving and the well-matched hydraulic system makes this kind of
pile drivers superior to other pile drivers of the similar rank, because of its 40% energy saving,
15% increase of speed and more than 40% raised pile driving force.
2. The new type of Step-like moving mechanism can do longitudinal, cross and rotary motion
freely, which makes it easy and agile to aim piles. A two- tier framework with cross and rotary
motion system has a compact structure which is easy to assemble. Specially designed rotary
13
 ZYJ680B－ⅡOperator’s Manual

compensating mechanism and rotary self-return function can largely decrease the resistance of
rotation and can reduce time for auxiliary work. Load balancing controller of longitudinal
motion mechanism can largely improve the reliability of vertical motion hydraulic cylinders.
3. The originally designed pile-clamping box is notable for accurate and reliable pile localization.
The pile stress resulting from clamping can be effectively decreased, and the problem of
clamping thin tube pile can also be solved.
4. Among pile drivers of the similar rank, SUNWARD series is the least in width which can
effectively decrease the distance of side pile when in normal pile pressing. The components
are easily disparted and transported.
5. The novel overall layout and special compact mechanism can deal with not only the side pile
near the building wall but also the troublesome corner pile. It improves the adaptability of
SUNWARD pile drivers evidently. It should be pointed out that the deed of many domestic
factories’ currently copying the above patents is illegal.
Ⅱ WELL-CHOSEN OUTSOURCED PARTS TO IMPROVE RELIABILITY
Quality of the outsourced parts is very important to performance of the whole pile driver. In order
to improve the pile driver’ performance, SUNWARD would rather use the outsourced parts of high
price. For example, our oil cylinder is made in well-equipped professional factory according to our
design; hydraulic pump is high pressure auto variable piston pump; crane windlass and hydraulic
motor for rotary are made in Sino-foreign joint venture company with introduced technique; the
balance valve and other key valves are ordered from noted foreign company.
Ⅲ IMPROVEMENT OF TECHNICS AND THE MANUFACTURE OF EQUIPMENT, ASSURING THE
QUALITY OF PARTS
Sunward pay special attention to the improvement of technics and the manufacture of
equipment .The key structures are made from high quality 16Mn steel plate which is cut with auto
cutter and welded by CO2 gas-proof welding technique. To improve performance of the large
components such as pile-clamping box and guidance beam, location surface and guidance surface
are mechanically machined without cost consideration; and assure the heat-treatment of key parts.
Ⅳ STRONG TECHNIC POWER, UPDATING PRODUCTS QUICKLY
The staff of Dept. of Research and Development is mainly from the Central South University
Mechanical and Electrical Institute. They are of creative talent and spirit. Our institute has a CAD
designing room of several hundreds of square meters and a laboratory of the similar size. We
provide optimum condition for research and development. ZYJ series static pile drivers are all
designed by advanced CAD technique.
In a word, Sunward has created a complete and innovative designing and manufacturing system
which is also capable of quick response to market changes. With the rapid developing pace,
Sunward is leading the world’s static pile driver market.

★ Remark：Above mentioned two kinds pile clamping box are optional, customer can choose anyone
base on real demand.
Special Attention：Always (every week) check the gap between guide wheel and guide rail in operation.
Once the gap is too wide or guide wheel no rotation，you should replace guide wheel and resetting position
for pile clamping box in time to prevent cylinder damage because of pile pressing cylinder uneven
bearing.

3.2.2 PILE PRESSING PROCESS

When it starts to press precast pile, the chief pile pressing hydraulic cylinder raises the clamping
box to the highest position. When the precast pile is put into the central hole in the box, clamping
cylinders extend and drive the jaws to clamp the pile. After that，operate the handle of the pile
pressing valve to let the chief pressing hydraulic cylinder work and strong hydraulic force will be
produced to press the pile into ground. When the clamping box reaches the lowest position, the
clamping cylinders raise the box and draw back. So the precast pile is pressed into the ground
base step by step in the cycle of “clamp pile→ press pile→ release pile→ return→ clamp pile …”
The chief pile pressing cylinder shall work alone if the needed pressing pressure is lower than P1.
If the needed pressing pressure is over P1, the chief and secondary pile pressing cylinder must

3.3 TRAVEL MECHANISM

It is a step-like traveling mechanism including vertical motion mechanism, longitudinal motion

mechanism, cross motion and rotation mechanism. By the three mechanisms, continuous step-like
travel can be carried out.
3.3.1 VERTICAL MOTION MECHANISM

It is mainly composed of four vertical motion cylinders and four cantilevers. The four cylinder
tubes are fixed by the four cantilevers to the machine body, and one end of their rods are jointed
with four wheel carriers in long ship slideway. When the piston extends, the main body rises,
otherwise it falls.

NOTE: Before the vertical motion cylinder telescopic, first make sure the cut-off valve
which on cylinder balancing valve is in open state.

3.3.2 LONGITUDINAL MOTION MECHANISM

It’s composed of two long ship slideways, two longitudinal motion cylinders joined to it and four
wheel carriers. When the piston of cylinder stretches out or draws back, there is relative motion
between the main body and long ship slideway.

3.3.7 ROTATION
There are five steps to carry out rotation. In every rotation, rotary angle is between 8°-11°.
3.3.7.1 Rotating procedure( see figure 3-11, 3-12)

Figure 3-11 Rotating manner

Step 1: Get the pile driver ready.

Step 2: Long ship slideways touch the ground, short ship slideways are lifted, cylinders in
short ship slideways go to the end vis-a-vis.

Step 3: Short ship slideways touch the ground, long ship slideways are lifted, cylinders in
short ship slideways go to the end vis-a-vis( the direction is opposite to that in Step
1). If the clearance between short ship slideways and long ship slideways is smaller
than the stroke of cylinders, the cylinders just need to go to the end of the clearance.

Step 4: Long ship slideways touch the ground, short ship slideways are lifted, short ship
slideways and rotary platform rotate around central axis and get back to original
place when rubber spring in rotary platform flexes.

Step 5: Long ship slideways touch the ground, short ship slideways touch the ground, then
return to original position.

3.4 HYDRAULIC SYSTEM ( FOR PILE PRESSING)

3.4.1 STRUCTURE
It is mainly composed of three pressure compensation variable pumps, three groups of manual
multidirectional valves，several oil distribution valve blocks and hydraulic cylinders as well as
some other supplementary hydraulic equipment.

1- Multi-directional valve A 2- Multi-directional valve B 3- Multi-directional valve C
Multi-directional valve A ---- It controls the extension and retraction of vertical motion cylinders
to adjust the altitude and level of platform, and to make the short and long ship slideways touch or
leave the ground;
Multi-directional valve B ---- It controls the job of pile pressing, pile clamping, pile releasing and
the rise and drop of clamping box;
Multi-directional valve C ---- It controls the stepping and rotary motion of pile driver.

3.4.2 WORK PRINCIPLE

3.5 SIDE PILING AND CORNER PILING (OPTIONAL)

When pressing side or corner pile, lift the chief pile pressing cylinder to the side piling frame,
have it installed, connect it with hydraulic hoses then it can work. The process of pressing side
pile is similar to that of pressing meso-positon pile. However, the secondary pile pressing cylinder
is not used during pressing side pile, therefore the operating handles for adding force and return
do not work here.

3.6 ELECTRIC SYSTEM

The machine is connected with three phase standard electrical supply AC380V(±5%), 50HZ.
Three oil pumps provide power. Two oil pumps with large power adopt the method of Y△ to
decrease the current impact to engine. This electrical system has some security measures for short
26
 ZYJ680B－ⅡOperator’s Manual

circuit, overload and phase failure, electrical leakage, ground connection and so on. To ensure
machine’s safe work, there is alarm system for “lifting machine”( see figure 3-22).
Safety rules: to ensure personal safety and equipment safety, the whole machine body must
connect ground firmly and the earth resistance must be kept below 4 ohm. Check machine
grounding status in every starting machine.

See appendix Fig 2 for electrical drawing.

3.6.1 COOLING DEVICE FOR HYDRAULIC OIL

In hydraulic system long time running, once oil temperature over 60℃ and temperature switch
test it, machine will warn operator to open cooling device. Start filtering pump at first, then open
cooling fan, and open cooling device. After that, buzzer warning will stop.
3.6.2 HEATING DEVICE FOR HYDRAULIC OIL (FOR NORTH USERS)
Hydraulic oil viscosity will be high in low surrounding temperature, which will make hydraulic
pump suck air or increase load, open heating device under this condition. Hydraulic oil
temperature meter will test oil tank temperature automatically. When temperature is less than
30℃, connecting electric heating circuit; after temperature reaching 35℃, cut off circuit and stop
heating. In hot weather, put heating power switch OFF to prevent miss-heating.

11．Simulate piling process. Examine hydraulic system and oil pressure, cylinder and main motion
mechanism. Assure they are at normal.
12．Assure that no abnormal phenomena are found, abnormities have been disposed correctly, and
potential factors of malfunction and security are all cleared up. Then begin piling work.

4.2.2 OIL PRESSURE ADJUSTING FOR SYSTEM, PILING AND LIFTING PILE(QUICK
PILING)

Fig 4-3 Overflow Valves Location 1

① Overflow valve F4(see Figure 4-3) is used to adjust rated pressure of the hydraulic system.
Set pressure of F4 as follows: After oil pump works normally, push handle Y3，Y4 to
“(return)” position, screw down adjustment nut of F4 slowly, watch oil pressure meter,
when the oil pressure is increased to Pa(24.5MPa), the rated pressure adjustment finishes.
Then screw down the stop screw of adjusting nut.
② Overflow valve F6, F7(see Figure 4-3) is used to set secondary pile pressing pressure Pd,
which can be set according to different needs ( see Chapter 8 for oil pressure and pile
pressing force). Adjust pressure of valve F6, F7 as follows: Start pumps till they run
steadily; push the handle Y1 to the position of “normal pressing “, handle Y2 to the
position of “pressing”, and handle Y3 to “forcing”; after secondary press cylinders stretch
to stroke end, gradually screw down adjusting nut of F6, F7; observe the oil gauge on
control panel; when the gauge directs to the needed value Pd, the adjustment is done.
③ Overflow valve F1 (see Figure 4-4) is used to set main pile pressing pressure. It is set as
PF1 ≤PF9. Adjust pressure of valve F1 as follows: Start pumps till they run steadily; push
the handle Y1 to the position of “normal pressing”, handle Y2 to the position of “pressing”,
30
 ZYJ680B－ⅡOperator’s Manual

after main pile pressing cylinders stretch to stroke end, gradually screw down adjusting nut
of F1; observe the oil gauge on control panel; when the gauge directs to the needed value,
the adjustment is done
④ Overflow valve F2 (see Figure 4-4) is used to set quick piling pressure. It is set as value
PF2 ≤10Mpa. Adjust pressure of valve F2 as follows: Start pumps till they run steadily;
push the handle Y1 to the position of “quick pressing” and handle Y2 to the position of
“pile pressing”; after the piston rod of chief pile pressing cylinders stretch to stroke end,
gradually screw down adjusting nut of F2; observe the oil gauge on control panel; when the
gauge directs to 10Mpa, the adjustment is done.

Fig 4-4 Overflow Valves Location 2

4.2.3 OIL PRESSURE ADJUSTING FOR CLAMPING AND RELEASING PILE

Overflow valve F3 (see Figure 4-4) is used to set pile clamping pressure. It is set as PF3≤PF9.
Adjust pressure of valve F3 as follows: Start pumps till it runs steadily; push the handle Y5 to the
position of “clamping pile”; gradually screw down adjusting nut of F3; observe the clamping oil
gauge on control panel; when the gauge directs to needed value, the adjustment is done. The
needed oil pressure for clamping is relevant to material and surface condition of piles. It should be
decided according to practical condition. If clamping is reliable, the set value should be kept low.
Overflow valve F5 (see Figure 4-3) is used to set pile releasing pressure. Adjust pressure of valve
F5 as follows: Start pumps till it runs steadily; push handle Y5 to pile releasing position, observe
pile releasing oil gauge, if the gauge value directs to 5-10Mpa, the adjustment is done. In the
operation, the releasing pressure is permitted to be set more than 5-10Mpa, but it should be less
than pile clamping pressure.
Attention: After any adjustment, please push handle to neutral position.

4.2.4 HYDRAULIC PUMP ADJUSTING

Adjust the chief hydraulic pump according to the following steps（see Figure 4-5）.

31
 ZYJ680B－ⅡOperator’s Manual

Fig 4-5 Hydraulic Pump Adjusting

（1） Place the handles of 3 multidirectional valves on neutral position, the hydraulic system
unloads (pull any multidirectional valve handle, the machine will be on loading position).
（2） Screw off plug of pump variable head (see figure 4-6); screw the limitation screw,
adjustment screw of overflow valve F4(fit in oil tank back side ) as loose as possible.
（3） Start oil pump, the variable head scale pointer should point at the full scale (10) position,
the pump supplies oil at full flux.
（4） Push handle Y3, Y4 (see figure 4-5) to “Return” position.
（5） Screw down adjustment screw of overflow valve F4. At the same time, watch the pressure
gauge, the oil pressure will be increased to Pb.
（6） Unscrew the pump’s adjustment sleeve till dial needle of pump variable head begins to
swing, then screw down adjustment sleeve.
（7） Screw down adjustment screw of overflow valve, till oil pressure is increased to Pa.
（8） Screw in pump limitation screw slowly; ensure that the pointer of pump variable head
points at X. Then lock with locknut and screw in plug.
（9） Push handle Y3, Y4 to neutral position.
（10） The adjustment is finished now. Then the pump’s flow and pressure vary automatically
according to the curves of quasi-constant power characteristics. (see Figure 4-7 ).

32
 ZYJ680B－ⅡOperator’s Manual

See the appendix table 8-7 for the specific value of Pb, Pa and x.

Note: The hydraulic pump model may be different because of different pile driver model and
customer’s different demand. The pressure-flow curve for A7V series hydraulic pump has been
adjusted when the oil pump leaves factory, so the above adjustment is not necessary.

4.3 OPERATION METHOD AND STEPS

4.3.1 START-UP
（1） Turn on the air switch. Turn on the power with key and be sure the all handles of
multidirectional valve are in the neutral (off load position).
（2） First start one pump, after a few seconds, the green indicator lamp turns on.
（3） Start another pump when the green indicator light turns on. (The interval is about 8
seconds.)
（4） Start 3 pumps one by one. Have them work for 3 minutes in the condition of no load. If no
abnormalities happen, continue the following procedures.
（5） Push the handle Y5 to the position of “Releasing pile”. Then oil pressure rises. If the oil
gauge labeled “pile pressing pressure” and “pile clamping pressure” shows the normal
pressure, push Y5 to the neutral. Then the job of start-up is finished.
4.3.2 POSITIONING PILE
Operate four stepping handles Z1~Z4 and four vertical motion handles S1~S4 to ensure correct
pile placement by the pile driver’s rotation, longitudinal and cross motion.
Before pressing pile, operate vertical motion handles S1～S4 to have the piston rods of four

33
 ZYJ680B－ⅡOperator’s Manual

vertical motion cylinders extend and long ship slideways land on the ground, short ship slideways
leave the ground. Then positioning pile is finished.
4.3.3 LEVELING
In order to ensure the verticality of piles, the main body of the pile driver should be kept
horizontal, which can be achieved by operating four vertical motion handles S1~S4 and at the
same time observe if the omnidirectional gradienter on the operating panel shows zero. If it shows
zero, adjustment is finished.
4.3.4 PRESSING PILE
4.3.4.1 OPERATING METHOD
Operate the three handles Y1~Y5 to carry out pile pressing (see§3.4.3 for reference).
Handle Y5 is used to clamp and release pile. When clamping pile, push handle Y5 to position of
clamping pile. After clamping oil pressure reaches the set value, push the handle to middle
position. If clamping oil pressure drops down during pressing pile because of clamping too long,
it should be done to push the handle Y3 to clamping position again to get clamping force. To
release pile, push handle Y5 to releasing position. After oil pressure reads zero, push the handle to
middle position.
The combination use of handles Y1, Y2, Y3 and Y4 can perform functions of “quick piling”,
“pressing pile”, “forcing”(forcing 1& forcing 2) and “lifting pile”. The former three functions are
four modes of pressing pile. They are different in piling speed and piling force.
（1） “Quick piling” refers to that the two chief piling cylinders are switched to special circuit,
and press pile quickly at a speed higher than that limited by pump displacement. To perform
quick piling, push handle Y2 to pressing pile position and handle Y1 to quick piling
position.
（2） “Pressing pile” refers to that the two chief piling cylinders take part in piling work at the
speed corresponding to pump displacement. To perform piling, push handle Y2 to piling
position and handle Y1 to normally piling position.
（3） “Forcing” refers that two chief piling cylinders and two secondary piling cylinders take part
in piling work together. When pile pressing force is balanced by the drag force on pile
driver from the ground (oil pressure for pressing pile reaches 24.5MPa), the two secondary
pile pressing cylinders should be used to add force. Push handleY3,Y4 to position of adding
force, the two secondary cylinders stretch out. Handle Y1 must be in the position of normal
piling and handle Y2 in piling position. After finishing a piling stroke, push handle Y3,Y4
to return position. After the rod draws back, then perform “lifting pile”.

ATTENTION:
When the piston rods of secondary pile pressing cylinders stretch out to add force on pile
clamping box, Y1 must be in the position of “normal pressing”, Y2 in “piling” position.
（4） “Lifting pile” refers to lifting clamping box.. First put Y1, Y3,Y4 in the middle position and
Y3,Y4 in the secondary pile pressing cylinders withdraw to the end, then push handle Y2 to
lifting position. Clamping box is lifted to the highest position. Push Y5 to the middle
position from the position of releasing pile and clamping oil pressure reads zero.

4.3.4.2 PRESSING PILE PROCEDURES

When piling a set of piles into ground, with the increasing depth and geological change the
pressing force becomes larger and larger. In order to improve efficiency, reduce power
consumption, assure piling quality and protect pile driver, the steps for pressing a set of piles are
to be taken as follows:
34
 ZYJ680B－ⅡOperator’s Manual

a) The first 1-2 stroke uses “pile pressing” in order to assure the piling verticality and find
out the ground geology.
b) After 1-2 piling stroke, if the oil pressure is lower than 5MPa, use “quick piling” until oil
pressure reaches 10Mpa. Then use “pile pressing” again. Changing from “pile pressing”
to “quick piling”, the displayed pressure value on the gauge will rise. Changing from
“quick piling” to “pile pressing”, the displayed value on the gauge will drop.
c) After 1-2 piling stroke, if the oil pressure is higher than 5 MPa, do not use “quick piling”.
d) If oil pressure reaches (24.5MPa)Pa during piling, then use “adding force”.
e) If oil pressure reaches (24.5MPa)Pa during adding force, then the piling force has
reached rated force , and the job of piling a set of piles has completed.
WARNING：
Before pressing pile, there must be enough counterweight on the pile driver; pile pressing force
should not exceed 680T. If the counterweight is not enough or the pile pressing force is too large,
the accident of “lifting machine” will occur. If the electric bell alarms, which warns that “lifting
machine” occurs, immediately push handles Y1, Y2, Y3 and Y4 to middle position. All personnel
except operator should leave away from the pile driver and keep a least distance of 2-3 meters;
After the oil pressure gradually drops down to zero and long ship slideways touch ground, push
handle Y5 to position of releasing pile; When “lifting machine” occurs, absolutely prohibit
pushing handle Y5 to releasing pile position first. If the clamping oil pressure drops during the
process of slowly releasing the piling pressure, it must be done to push handle Y5 to position of
clamping pile for load. When “lifting machine” occurs, it is also prohibited to operate the crane. If
the crane has been lifting objects, the objects should be unloaded. When the accident has been
solved, the pile driver should be paused to find out causes of “lifting machine”. Before continuing
work, measures must be taken to prevent the accident of “lifting machine”.
Sunward shall not be responsible for any legal or economic responsibility caused by “lifting
machine”.

“Lifting machine”------referring to that the main body and long ship slideways are lifted
off ground because of not enough counterweight or piling force exceeding the rated force.

“Machine falling down”---when pressing pile, pile pressing cylinders release piles
abruptly, so that pile driver loses support and falls down suddenly. It can cause serious
injury to personnel and the machine itself.

ATTENTION：
1. In normal condition, it is not allowed to pull pile with pile driver. Pulling pile refers to
pulling out the pile that has been pressed into ground. If there is special condition and it
must be done to pull pile with pile driver, you must make sure that the pulling force is
less than P2tf (see the appendix table 8-1), the system oil pressure is less than Pa, and
weight of pile driver with counterweight is less than P3tf. Otherwise partial
counterweight should be removed. When pulling pile, short and long ship slideways
should be layed down on ground and nobody is permitted to stand under clamping box.
After finishing pulling work, check the joint seat between chief cylinders and clamping
box whether it is normal or not. If pile driver inclines during pulling pile, the pulling
work should immediately be stopped.
2. If piling pressure exceeds 10Mpa, push handle Y2 to middle position to release pressure，
then push handle Y5 to the position of releasing pile. If six cylinders work together, the
35
 ZYJ680B－ⅡOperator’s Manual

handle Y3,Y4 should also be pushed to middle position to release pressure. After piling
oil pressure gradually drops down, push handle Y5 to position of releasing pile.
Otherwise, great impact would occur! Sunward is free from any responsibility for such
incorrect operation.
3. If pushing handles has to be done or has been done, please remember, at any moment, do
put all handles of multidirectional valve to the middle position to unload, which will help
to save energy, reduce the generation of heat, protect pile driver and assure safety
operation.
4. When working at reconstruction site, especially at the bricks or blocks largely imbedded
stratum, form holes with steel pile first to avoid possible pile break.

4.3.5 ATTENTION
 Pay attention to the verticality of piles and the leveling of machine body during pressing pile.
 Operate handles and buttons gently avoiding rough operation.
 Check at any time whether oil pressure and oil temperature are normal. (The max. oil pressure
should be Pa(24.5MPa), oil temperature between 35°～85°). If any abnormalities occurs, stop
machine immediately to dispose abnormalities.
 A set of pile to be inserted into the same location must be completed continuously. If there is a
long break during the process, the pile inserted in ground might solidify with the ground earth.
When piling process resumes, the oil pressure would increase sharply.
 When pile driver moves, rotates, or rises and falls in large range, it must be guided, cooperated
with ground personnel. The operator must keep close watch on the pile driver motion and
communicate with the ground personnel in time. If there is any abnormality, immediately push
the valve to middle position.
 When pile driver moves, rotates, rises or falls, if oil pressure increases, it indicates the related
cylinder has gone to stroke end. Immediately push the valve to middle position.
 While pile driver moves or rotates, the electrical cable should not be pressed by long or short
ship slideway, or blocked by obstacles for which the electrical cable can not move with the pile
driver.
 Electrical cable can neither be grinded by trucks nor covered by objects.
 While pile driver runs, pay attention to the hoses linked to long and short ship slideway, assure
they are not stumbled or blocked by other parts, in case the hose might be pulled broken.
 If a sunk accident occurs while pile driver runs, operator must lay down the long and short ship
slideway to touch the ground, remove the counterweight from pile driver, and then dispose the
accident. The counterweight of inclined side should be removed first.
 When pile pressing cylinders are working, it is prohibited to release pile.

Sinking accident--- It means that pile driver sinks into the ground because the soft ground cannot
support. At that time the pile driver cannot move by itself.

4.4 INSTALLATION AND REPLACEMENT OF CLAMPING JAW

4.4.1 INSTALLATION
We produce two types of clamping box, one is round & square clamping boxes, the other is
thin-wall tube pile clamping box with cylinder installed vertically. See the following pictures for
installation manner. Because of the difference in pile driver model or buyer’s needs, the clamping
box type of corresponding main machine may be different. Operators should handle it according
to different types.

5.5 DAILY SERVICE AND ROUTINE MAINTENANCE

1. Examine fixing screw bolts for any looseness. Specially pay attention to those fixing screw
bolts on the pressing cylinders, vertical motion cylinders, crossing motion cylinders and
clamping jaws, as well as the joint screw shaft and screw nuts between cantilever and its seat.
Be sure to keep even torque moment if there are several fixing screw bolts. The mounting
bolts of clamping cylinders of thin-wall tube pile clamping box should be tightened again
after the new machine has worked one or two days.
2. Take care to keep the hydraulic system clean. The adding oil of hydraulic system requires
special oil adding equipment and the transmissivity of its oil filter should not exceed 20 μ.
3. Lubricate the machine termly.( see the table §5-6LUBRICATION DIAGRAM )
4. Clean dust and dirty things after work.
5. If it works for the first time, you should change all oil after a month and clear the oil tank.
After that, change oil every half a year. (Be sure to clean used oil in tank, tubes and any units)
6. Keep oil return filter clean. If the return oil manometer shows a pressure over 0.4 MPa, clean
or change the core of the oil-filter. Clean it every month.
7. Screw down every fixing screw bolt on all pipe connections and units every month.
8. If the color of the oil becomes white and muddy, replace the oil. Otherwise the hydraulic
elements will break down earlier than expected.
9. In order to assure the accuracy of the oil gauge, it should be checked periodically. Normally,
interval of check is half of a year. When in another work site or the manometer doesn’t point
to zero, unscrew the oil-filling plug loose, when the pressure inside and outside the
manometer are the same （it needs about 1 minute）, screw the oil-filling plug tight, then the
manometer can work normally.
10．When replacing new pump, you should fill up oil in leakage pipe, connect the pipe with
leakage coupler (not screw down), start pump, and screw down coupler nuts when oil leaks
from coupler.

6 CRANE QY25C
QY 25C crane is installed in ZYJ hydraulic static pile driver as a pile lifting device, which is an
auxiliary device. The crane’s structure is similar to the superstructure of general hydraulic truck
crane and it is mainly composed of jib system, windlass system, slewing, and hydraulic control
systems.

The superstructure of crane is installed in the machine frame, which is connected with the inner
part of slewing support, while the outer circle of slewing support is connected with the base of
crane. The crane base is welded on the main machine of ZYJ hydraulic static pile driver.

6.1 ATTENTION

 The main machine operator and crane operator should keep good communication and
observation for each other. Prohibit operating crane or hoisting objects while the machine
moves or rotates. And also, prohibit the machine moving or rotating while crane is in
operation or hoisting objects.
 Ensure firm binding while hoisting pile.
 Crane’s winch wire should wrap around the drum for at least 4 circles.
 When lifting pile, it is prohibited to stand in the working range of crane.
 Check winch wire and pile lifting wire often and replace them if any damage occurs.
 Check and screw down the connection bolts at the crane slewing support every 2 months,
the screwing down torque is 1100 N·m. Replace them with original SUNWARD bolts if
any abnormality occurs.
 Lift rated weight within the limitation of jib lifting angle to avoid crane jib overloading.
 Before pressing piles, make sure the hook has been separated from the tools for lifting
pile. If not, there will be serious accident of the lifter and pile driver. In some special
condition, if the crane winch has to be used as pile follower, the speed of giving pile must
be higher than the speed of piling.

Fig 6-2 Jib Structure

1—Jib body 2—Telescopic jib

Jib system includes main jib, flexing jib, two parallel connected
derricking cylinder, and driving system of expansion jib, etc.
When extending or retracting jib, place the jib horizontally and
pull out two shafts that fix expansion jib, then pull the operating
handle of multidirectional valve to operate the jib expansion
motor, so that the expansion jib expands relatively to fixed jib.

Note:
When extending or retracting jib, the angle between jib and
Fig 6-3 Telescopic drive system
horizon should be less than 10°. There are two adjustable
jib lengths. After the jib length is adjusted, fix the extendable
jib on fixed jib with shaft pin and lock bolt.

6.2.2 WINCH SYSTEM

Winch system is composed of hydraulic motor, reducer, windlass

drum mechanism of brake, windlass wire and pulley block.

Fig 6-4 Winch Structure

6.2.3 SLEWING SYSTEM

Slewing system includes a hydraulic motor, reducer, small gear, and slewing support. The slewing
support is fixed on the machine seat. Hydraulic motor drives small gear via reducer, the small gear
turns around the large gear ring on slewing support, making the crane slew

6.2.4 DERRICKING SYSTEM

It is used to change the jib angle.

The amplitude of QY25C crane is realized by the extension and retraction of cylinder, so that the
horizontal distance between the hook center and slewing center，i.e. the amplitude, changes.

6.2.5 HYDRAULIC SYSTEM

See figure 6-6 for hydraulic system. A hydraulic pump( installed in the side part of main machine)
supplies pressure oil; the system pressure is determined by overflow valve of multidirectional
valve, the pressure is set as 18Mpa.

6- Expansion motor 7- Balance valve 8—Hydraulic oil tank 9—Hydraulic pump

Manual multidirectional valve includes 4 manual control valves and 1 pedal valve, achieving
derricking, winch, slewing, jib extending & retracting, and speed control. Pull multidirectional
valve handle and treadle the pedal to achieve smooth derricking, slewing, and windlassing.

To adjust cold weather in northeast, user’s can choose northeast configuration oil tank which can
heating oil.(see fig6-7)

Fig 6-7 Hydraulic oil tank heating schematic diagram

6.2. 6 SAFETY DEVICE

1. Jib overload protection

Adjust the adjustment screw on derricking hydraulic cylinder equalizer valve (if screw clockwise,
the pressure lower; screw counter clockwise, the pressure higher). The oil pressure which limits
the jib lifting should not exceed 18 Mpa to prevent the jib overload. If the jib falls when windlass
loads, which means the jib lifting angle is too small, it should be done to lift the jib and then begin
to windlass.
53
 ZYJ680B－ⅡOperator’s Manual

Fig 6-8 Hook limitation protection

1- Connection box 2- Heavy hammer

2. Hook limitation protection

When hook reaches upper limit, the hydraulic system unloads and windlass stops to rise. Its
working theory is as follows: When the hook reaches upper limit, hook assembly props up the
hammer which is wrapped by wire rope, control switch connected with hammer switches on the
electromagnetic valve, then the right position is switched on, overflow valve off-load, the winch
lifting stops; pull the winch control handle to falling position, the process switch on control handle
switches off the electromagnetic valve, the electromagnetic valve gets back to left position, the
hydraulic system works normally, achieving falling hook, and the hook disengages from upper
limit（see fig 6-9）
3. Torque limitation protection for the jib
The instruments will display different lengths, appropriate inclination angles, lifting weight and
other parameters at real-time. It can also tell the torque limitation weight with the lifted object in
the current position. When the torque limitation weight is reached, it will give prewarning and
warning to alarm operators.
A power switch is installed in the right of instrument panel. After electricity failure, you have to
repeat once the movement of switch-on and switch-off to electrify. It starts to work normally
when buzzer is sounding.
Note: The instrument for torque limitation is optional, if customer needs to buy it, the
requirement should be made clear in the purchase contract.

5. The joints, hose and seals must be the right type as designed.
6. Choose place without dust to dispart and assemble hydraulic elements.
7. When fixing the oil gauge, the oil-filling plug (safety plug) should be screwed loose so that
the vent of oil-filling plug can link the atmosphere. During un-using period, screw oil-filling
63
 ZYJ680B－ⅡOperator’s Manual

plug tight to prevent filling liquid from leaking. During work time, if it happens that filling
liquid level rises or becomes full of gauge, replace the old gauge with a new one.
8. It should be carried out or supervised by qualified electrical worker to examine or repair the
electrical system. Also the local manual books of electrical repair and electrical safety should
be obeyed.
9. If it is necessary to use welding method, things must be done before welding are preparing
welding material and filling material, deciding welding method, switching off all electrical
power to the pile driver, as well as fire fighting equipment.
10. While welding, electric current is not permitted to get through the vertical cylinder from long
ship slideway to platform, nor from platform to long ship slideway. No current is permitted to
be conducted by any cylinder nor to get through between rod and cylinder tube. It is not right
to conduct electric current by iron joint either. The correct method is to connect the cable
directly to the part to be welded. If machine body need weld, first make sure the 24V DC
power supply without 220V AC (the indicator lamp should not light)
11. If welding task is carried out near cylinders, the rod part stretching out of cylinder tube must
be enclosed up with asbestos cloth in case that welding dregs splash to the rod to damage the
cylinder.
