1. PRESENTATION
LOADTRONIC II is an automatic and dynamic weighing system for wheel loaders. It is
automatic in the respect that the load in the bucket is weighed without any involvement
from the operator, and dynamic as the weighing is done while the machine operates
normally without any interruption for weighing.

LOADTRONIC II is meeting the international recommendation, OIML R51, and is therefore

equipped with a calibration enable switch on the bottom of the main unit. If the system is to
be used as an approved equipment, the switch must be sealed and can only be opened
by a representative from an approval organisation.

1.1. Sensors
LOADTRONIC II has two pressure sensors fitted to the hydraulics in the front frame of the
wheel loader. These sensors measure the forces applied to the lifting arm system.

There are three further sensors in the system:

>> One angular sensor (inclinometer) which
measures the position of the lifting arms.
>> One acceleration sensor which measures the
movement (accelleration, retardation and the
inclination of the machine).
>> One position sensor to signal when the bucket
is fully retracted.

1.2. Main unit

The main unit is a combined operator’s display with an intergrated
computer unit added to the back of the display. The main unit is mounted on
the right corner post in the cabin, and has the following functions:
>> Reads sensors
>> Computes and analyses measured data
>> Controls the automatic weighing function
>> Records and reports the weighing results
>> Carries out calibrating and similar functions when the calibration switch is
set to the open position.

1.3. Display unit

The display unit is integrated in the main unit,
and has the following functions:
>> Shows results
>> Is used for dialogue with the operator
through a keypad.

1.4. Printer (optional equipment)

The printer is connected to the main unit and
positioned as required (designed to be mounted
in the radio slot in the upper left corner of the
cabin roof).

The printer has the following functions:

>> Prints a load receipt for each truck load.
>> Prints reports about customer, truck,
material, machine and load list.

If printer is connected, pressing will print the load receipt. This will automatically
cancel/zero the running accumulated total for this truck. See chapter 6.

 OPERATOR’S INSTRUCTION MANUAL 15

3.3. Automatic weighing

Normally the LOADTRONIC II is in the mode for automatic weighing. In this mode the
operation of the loader controls the functions of the LOADTRONIC II system.

Automatic weighing means that the operator can operate as usual. The LOADTRONIC
itself determines when a new bucket should be weighed. The weight of the bucket is
automatically added to the existing total. Neither the moving of the machine or the lifting
movement need to be interrupted for weighing the bucket and no key needs to be pressed
to update the total weight. This applies to normal work such as loading trucks or
transporting loads.
The automatic weighing is connected to the normal working cycle as shown in the
illustrations below:

Figure 3.3: Automatic weighing sequence

A: -20° to +30° B: 2 seconds C: Weighing

Issued 2005 - Copyright © AADI AS - All rights reserved

 OPERATOR’S INSTRUCTION MANUAL 16

During automatic weighing the display unit shows:

>> Material weight, e.g. 7.50t LOADTRONIC II A1
>> Remains (“Rest” to be loaded Load : 7.50t
(the required final weight - Remains : 20.80t
(minus) total load so far)), e.g. 20.80t T:unspc : 15.90t 2
>> Total weight loaded so far, e.g. 15.90t
>> Number of buckets loaded so far, e.g. 2

NOTE: If the bucket is not fully tilted rearward, the message: “BUCKET” will be shown in
place of the bucket weight (no weighing performed).

When
>> The LOADTRONIC II is activated, the current material weight is shown.
>> When weighing begins, the bucket weight will flash on the display unit.
>> Weighing is completed when the flashing stops and the weight figure is stable.
>> The total weight and the remaining weight to be loaded will be updated.
>> The last material weight remains displayed until the next time loading begins.

3.3.1. Best result when weighing

Maximum function and accuracy is achieved by avoiding substantial deviations from the
usual work cycle, while at the same time noting the following points:

>> Before starting to load and some times between filling the bucket it may be
necessary to move some material and tidy the work area. The operator should then
put the LOADTRONIC II in the pause position by pressing . When this
additional work has been completed and before starting to load, activate the
LOADTRONIC II again with . (see chapter 4.3). If the LOADTRONIC II is not
put in the pause position there is a risk, that some of the material will be weighed
and thereby added to the total load. If the operator forgets to push the pause key, it
is possible to use the cancel function to remove the weight of the last
bucket, even if it may have been emptied, see chapter 4.5.3.

>> The loading cycle begins by driving forward and pushing the bucket into the heap.

>> The LOADTRONIC II is activated/made ready for weighing 2 seconds after the gear
selector has been moved into reverse. During this time the bucket should be pulled
out from the heap, from which the material is being taken, so that no friction forces
between the heap and the bucket will affect the weighing result. This particularly
applies if the bucket has been raised fairly high while filling it.

>> The lifting arms must be moving upward to initiate the weighing.

51107 07/06 Issue #1
 OPERATOR’S INSTRUCTION MANUAL 17

>> If it should happen that the LOADTRONIC II does not become activated / begin
weighing, it is possible to activate manual weighing by pressing ,
see chapter 4.2.

>> The bucket must be tilted rearward to it’s end-stop when weighing, otherwise the
message “BUCKET” will appear on the display.

>> The lifting arms must be lifted sufficiently high, ref. Figure 3.3.

>> The lifting arms must not be lowered so much that they push against the front
frame or body of the machine when the weighing begins. This could cause false
readings. This means that:
> During loading - carrying work, it is possible to control at which point in the work
cycle the weighing should be done by waiting with the raising of the lifting arms
until, for example, the machine is driven across level ground.
> When loading and transporting and dumping the load at a low height, e.g. down a
slope, it is necessary to raise the bucket before emptying it to allow weighing to
take place.

>> When weighing on ground which is inclined more than 5 %, it is recommended that
weighing should be avoided at low lifting angles particularly when the machine is
pointing downhill. The system will only weigh when the tilt is less than 10 %.

>> If the operator wants to weigh the load under controlled conditions (to achieve the
best possible result or to weigh the load again when the first weighing result is
doubtful), it is possible to use the cancel function or the manual activating function.
If the bucket is empty, the cancel function must be used. At manual activation a
new weighing sequence starts immediately. When cancelling before dumping, the
system must also be activated for a renewed weighing by moving the gear selector
from forward or neutral to reverse.

THE BEST RESULT IS ACHIEVED WHEN :

> The bucket is raised at an even speed from low to high
( above the horizontal level )
> The travelling speed of the machine is low

4. CHANGING THE SET-UP
For various reasons the operator may chose to re-weigh a load or do other changes to the
system.

4.1. Target load, a pre-defined total pay load

The loader will deliver material bucket by bucket. Each bucket is weighed and Loadtronic
II keeps track of the accumulated, running total. In most cases the truck or hauler have a
maximum permitted load limit, due to axle pressure, road condition or other reasons. It
could also be that the customer has pre-defined the amount of material he wants
delivered.

In both cases Loadtronic II is prepared for this by simply programming the total load which
is to be delivered. This is done in the following steps;

1. Complete the task described in 5.2. This will make the system ready for a new load
cycle with unspecified records.
2. Press and select the truck as described in 5.3/5.4 or continue with the
unspecified record.
3. Press once to position the cursor where you are allowed to type in the pre-
defined/required total load by typing eg. 3500 which will predefine the load of
35.00 tonnes.
4. Press and the Loadtronic II returns to the automatic weighing mode.

5. The display will now show the additional information,

“Remains: 35.00, which will be updated/lowered
each time a new bucket is loaded. LOADTRONIC II A1
Load : 0.00t
Remains : 35.00t
T:unspc : 0.00t

Note 1;If this is a permanent target load, the pay-load, for the truck/hauler eg. the
maximum load capacity of the vehicle, this may be programmed into the
specification of the truck as described in chapter 8.5.

Note 2:To reach the target load, normally the “shake off” function in chapter 4.5.2 will
have to be used.

 OPERATOR’S INSTRUCTION MANUAL 19

4.2. Manual activation of weighing sequence

During normal operation the weighing sequence is done automatically when the wheel
loader is reversed out from the material heap after the bucket has been filled. The
weighing begins as soon as the bucket has moved within the weighing range and provided
that the other signals are also acceptable.
Manually activation, however can be introduced simply by pressing , which activates
the system immediately.

Manual activation is required for re-weighing material which has been lifted e.g.
>> If part of the load falls off while moving
>> When adjusting the loaded amount and then re-weighing

Manual activation means that any weighing which has started will be cancelled. This
applies even if the weighing has been completed, but before the bucket has been
emptied.

4.3. Pause function

Loadtronic II can be set in a “PAUSE” mode when tidying the work place or carrying out
other work when the load in the bucket should not be weighed or recorded.

Pause is selected by
1. Pressing (if you are in automatic weighing mode). When the LOADTRONIC II is
in the pause mode no buckets will be weighed or recorded. The display will show a
row of “ – “ signs, ref. Fig. 4.3.

The pause mode is ended by:

2. Pressing (in pause mode).
The LOADTRONIC II returns to automatic weighing.If the key is pressed after the
loading/weighing has begun, the current bucket is cancelled.

4.4. Adjusting display backlight

When in the pause mode, the intensity of the background light of the display can be
adjusted by pressing once or several times.

4.5. Adjusting weight

4.5.1. Re-weighing material in the bucket

If the bucket has already been emptied, the cancellation must be confirmed,
ref. Chapter 4.5.3.

Proceed as follows in order to re-weigh the material in the bucket:

1. Press (the bucket weight is cancelled/subtracted from the running total weight,
and the current approximate weight is shown on the display).

2. Move the gear selector to forward drive and then back to reverse, to initiate the
weighing. The machine does not have to be moved.

3. Raise the bucket evenly from below the horizontal level and its load will be weighed
again. Alternatively, the manual activation function can be used, see section 4.2.

4.5.2. Adjusting material weight (shake-off function)

Proceed as follows in order to adjust the material in the bucket:
1. Press the current material weight is subtracted from the running accumulated
total, and the current approximate weight is shown on the display).

2. Move the machine to a place to shake of the material until the display shows the
approximate desired weight.

NOTE: The weight shown is lower than the actual weight, since the bucket is not
tilted rearward.

3. Tilt the bucket rearward to stop and move the gear selector to reverse to initiate the
weighing. Raise the bucket evenly from below the horizontal level and the load will
be weighed again.

NOTE: Surplus material is dumped back into the bank of the material, the rest of
load in the bucket must be re-weighed.

 OPERATOR’S INSTRUCTION MANUAL 21

4.5.3. Cancelling/dumping last bucket

Proceed in the following way if the last bucket is not to be added to the
load on the truck and should therefore be cancelled from the total
weight, since the material is dumped back into the bank.

1. Empty the bucket and press (the LOADTRONIC II requires

acknowledgement that the weight of the bucket really is to be
cancelled). See fig. 4.5.3.

2. Press (The weight of the bucket is set to zero and is

deducted from the total. The LOADTRONIC II returns to
showing the automatic weighing.)

 OPERATOR’S INSTRUCTION MANUAL 22

4.5.4. Immediate recording with specification

It could happen that the operator has missed the preparation stage when it comes to
specifying or linking the load to a truck, material and/or a customer. The operator still has
this opportunity as long as the material still is in the loader bucket (un-delivered). Although
it appears on the display that the previous specification (truck, material and customer) is
still in use, the following steps will help out in this situation. The same can obviously be
done if an “unspecified record” is in use. A proper specification may still be achieved.

For example, the operator has loaded 6.30 tonnes LOADTRONIC II A1

which is currently in the bucket. The operator has Load : 6.30t
continued to operate with the old specification : 0.00t
(valid for the previous truck). It appears that truck T:ST20468 : 34.80t 5
identified as ST20468 is about to receive 6.30 tonnes
of material, bringing the total up to 34.80 tonnes.
The operator realizes that this is the wrong speci- LOADTRONIC II A1
fication and needs to pull up a new specification. Load : 6.30t
: 0.00t
T:FORD : 6.30t 1

1. With the material in the bucket, press .

2. This will bring you into the menu described in section 5.4.
3. Select the new specification, linking the load to truck, material type or customer

When finished, press to return to automatic weighing which now shows the
specification which was selected.

 OPERATOR’S INSTRUCTION MANUAL 23

4.6. Using several attachments

The Loadtronic II can be set-up to accept 5 different attachments. Please refer to section
8.1, which shows how to change between/select different attachments. The display layout
in the automatic weighing mode indicates a reference code to which attachment in use.

The first time a specific attachment is used the operators must;

>> Tare the attachment as described LOADTRONIC II A1

in section 7.1 Load : 7.50t
>> Perform a basic calibration as described : 0.00t
T:unspc : 15.90t 2
in section 7.2
In this example, attachment no.1
is in use, indicated as “ A1 “

This is required for an accurate measurement. The tare function and basic calibration
eliminates the dead weight of the attachment and compensates for any change of the
centre of gravity.

If the attachment already is used and recognized by the system, the operator just selects
the attachment by pressing as described in section 8.1.

Zero point adjustment is required when the ATTACM. : 1

attachment is changed. Access to this feature is Type : strt. buck.
+ : next v : 0-adj.
done by pressing as described in section 7.4. : OK > : (RT)

The system will block the automatic weighing and indicate the requirement with the normal
message “Adjust Zeropoint” until the zeropoint adjustment has been done.

5. RECORDING
Each time the loader is used to move material and the normal weighing sequence is
carried out , figure 3.3, the Loadtronic II has made a recording. The recording is done with
or without reference to a specific truck type, type of material or customer. The recording is
done internally in the unit onto a record which is activated during the operation. This
record may be inspected by identifying the truck, material or customer again at a later
stage and a report may be printed.

5.1. Active record

LOADTRONIC II can differentiate between 1000 different trucks, 1000 different materials
and 1000 different customers. Truck/material/customer number 0 is unspecified and is
used when specification is not required. The remaining, 1 - 999, are used as reference
numbers to identify trucks, materials, and customers. If desired, the number can also be
replaced by text with up to twenty characters, which can be displayed instead of a number.
See also chapter 8.5.

Each truck has a “record” tied to it. This record contains the total pay load / load capacity
of the truck together with the material and customer which were specified the last time the
truck was loaded.
ACTIVE RECORD
A “record” is tied to each load.
This record appears in the Data which can be typed in by the operator before loading:

 OPERATOR’S INSTRUCTION MANUAL 25

The record should be created or an existing record should be activated before starting the
loading of the truck by specifying which truck is to be loaded and making changes or
indicating new specifications for total payload, material, and customer on the “record” for
the truck.

The loaded truck can remain “unspecified” or have a number from 1 to 999. The same
applies to material and customer. When loading from several places, (e.g. with different
owners) it is easy to distinguish between loading places by giving the different places a set
of material numbers, e.g. 1 - 9 for one place and 10 - 19 for the next place (10 could be
unspecified for loading place 2) and so on.

The accumulated weight and the number of buckets are set to zero when the record is set
up. Then each bucket is added to the accumulated weight in the “Active record” when the
weighing has been completed or the bucket is emptied.

Each load is recorded in the list together with the finishing time. Afterwards LOADTRONIC
II can provide reports showing supplied material per truck, kind of material and customer.

All material moved by the loader is recorded. This information may, at any time, be
inspected and printed out. Following the instructions in figure 6 by operating and then
, you enter into the report file menu.
The display will now show the “Customer” menu. The display shows the total weight of all
material delivered, the current date, to the “unspecified” customer. If you want to look at
the weight delivered to a customer which was identified with a specification (code, text or
number), simply scroll through the list up and down using or .

If you do not want to look at “all” delivered material, but specific material types which are
identified by code, text or number;
>> Press to select the “Matr:” position on the display and simply scroll through the
list up and down using or or just press material number, e.g “450”.
If you want to look at the above data but delivered at a different date;
>> Press to select the date position on the display and simply scroll through the
dates the loader has been operated by using to go backwards in time.

If you need a printout of this report, simply press and a total of all “Customers” will
be printed and the system returns to automatic weighing.

You are also able to generate the same kind of reports as described above but looking at
“Material”, “Truck” or the total usage of the “Loader” in stead of “Customer” as described
above. Figure 6 shows that the different menus are accessed simply by operating .

The final report option is the “Load” report. When this menu is entered the last load
handled by the machine is displayed. Typically this will show;
>> which number this record is out of the total, eg. L10; Load number 10 of today.
>> the date L10 was done
>> time of above
>> the weight of the material and the specification
>> the customer
>> which truck transported the material
This will re-generate the load receipt when is pressed.
If a total load list of the selected day is to be printed, use for this special print job.

7.1. Tareing attachment

Calibration must be enabled. Tareing means zero-setting of the load readout with the
attachment fitted.
(The computer will measure the deadweight of the selected attachment and only monitor
the material carried by the attachment)

When tareing, the LOADTRONIC II records the forces in the lifting arm system within the
whole lifting range. The attachment must be empty and the computer stores a tare curve
for the respective attachments.

1. Fit the attachment to the machine.

2. Check that the attachment is EMPTY.

3. Place the machine on level ground with the lifting arms horizontally. The
attachment should be fully retracted against stop.(Regarding carrying position for

asks for the reference weight, which is the weight BASIC CALIBRATE A1
Ref. Load : XX.XX t
of the material in the bucket.

Set the reference weight: : OK

Alternative 1
The reference weight is known with an accuracy within 0.5 %, for example, when
weighing on a weigh-bridge or using approved weights. Set this weight on the
display unit (+/- or numeric keys). The calibration weight must weigh approx. 40 %
of the tipping load of the machine.
Alternative 2
If an accurate determination of the weight of the loose material in the bucket
cannot be made, estimate the weight as carefully as possible and set the value.
After the basic calibration has been done, the attachment must be recalibrated
by testing with an accurately known weight, for example, a stone,
before the calibration is complete. See chapter 7.3

7.4. Zero point adjusting

Prior to performing a zero point adjustment, make sure that the machine has normal
working temperature. This will result in the most accurate adjustment.

Zero point adjusting should be carried out each time the machine has been idle for a
while, or at least every hour. During normal operation, the zero point can be adjusted up to
+/- 2% of max load.

After 50 minutes, the operator is shown a request on the display unit to carry out zero
point adjusting. After 10 more minutes (total 1 hour) the system will block weighing until

the zero point has been adjusted (the load will show “
****”).
Zeropoint adjustment is performed in the following steps:

1. Check that the attachment is EMPTY!

2. Place the machine on level ground with the lifting arms horizontal. The attachment
should be fully tilted rearward to stop. If not, the system shows the message
“bucket” and aborts the function.Pallet fork should be in the carrying position,
see chapter 8.7.

8.7. Using pallet fork

During tareing and basic calibration, the attachment should always be in the same position
when weighing commences. When using a bucket, this position is when the bucket is tilted
fully rearward (fully rolled back).

Pallet fork
When using a pallet fork, the induction sensor for the
bucket positioner is used. The induction sensor is
adjusted so that the pallet fork automatically takes up
the carrying position (the same position as during
tareing and calibration).

NOTE: The position of the induction sensor must

therefore be marked for the respective attachments. Figure 8.7: Pallet fork

8.7.1. Setting the Volvo induction sensor

>> Place the attachment in the required position
(carrying position).
>> Turn off the engine, leave the ignition
key in running position.
>> Loosen screw (A) and displace the bracket (B)
to its rear position.
>> Press the switch for the bucket positioner.
>> Move the tilting lever to the rear detent position.
>> Displace bracket (B) with the switch towards Figure 8.7: Induction sensor
the rod (C) until the tilting lever returns
(is “kicked-out”) to neutral position.
>> Tighten screw (A).

Important!
The distance between the induction sensor and
the actuating part of the machine should be
3 - 5 mm (0.12 - 0.20 in). See the adjacent figure.

8.8. Basic preventive maintenance

To safeguard correct weighing the following must be checked:

Daily

>> Lubricate the upper bearing of the lifting arms and the bearings of the lifting
cylinders.
>> Adjust the zero point when starting work for the day, preferable when the machine
has reached it’s operational temperature, see chapter 7.4

Recommended weekly

>> Check the calibration with a reference weight or a load weight.

NOTE:
Washing with high-pressure jet is not permitted for removing dirt and
accumulated material around the sensors.

 OPERATOR’S INSTRUCTION MANUAL 56

10. EXAMPLES ON HOW TO USE
10.1. Loading a truck
The operator knows that the machine has been stationary since the previous day. He
therefore moves the wheel loader to a place which seems level, particularly sideways.
While the machine is stationary he carries out a manual zero point adjustment as
described in chapter 7.4.

Then he moves the machine to the place of loading. As neither truck, material or customer
has to be specified this time the operator presses to initiate an unspecified load, see
section 5.2.

The loading begins and he fills the truck in the way he has always done before the
LOADTRONIC II system was installed. However he avoids spilling material on the way
from the heap to the truck. When the truck is full after three full buckets and a half, the
display unit shows the total weight of the load on the truck on the bottom line.

The operator informs the truck driver of the weight and then presses to make the
system ready for the next truck to be loaded.

While he is waiting he intends to tidy up the work site and to dump the material back into
the heap and therefore presses while he is in the automatic weighing mode in order
to pause the LOADTRONIC II, so that weighing is not continued until pause is removed.
The line for the bucket weight only shows dashes, see section 4.3.

A new truck arrives. The machine operator re-activates the Loadtronic II form pause by
once again pressing . He checks that the unspecified total value is 0.00 tonne and
begins to load.

In the second bucket he discovers a large stone. The stone should not be included and he
therefore dumps the whole bucket load to one side. The weight of this bucket should
therefore not be included in the total. He therefore presses to cancel the last bucket.
The LOADTRONIC II does not know whether the bucket has been dumped onto the truck
and therefore asks for confirmation in case the operator should have pressed by
mistake. The operator once again presses and thereby confirms that the last bucket
is not to be included. See section 4.5.3. for details.

51107 07/06 Issue #1
 OPERATOR’S INSTRUCTION MANUAL 57

When transporting the third bucket, some of the material falls off. The display shows the
bucket weight as flashing number and the operator understands that weighing has been
carried out both before and after he dropped a material. To determine the correct bucket
weight he therefore presses to manually activate the weighing again. He continues to
slowly raise the lifting arms and drives a little slower to give the LOADTRONIC II time to
weigh the bucket again. When the bucket weight begins to flash, the operator knows that
the weighing has restarted and he can therefore concentrate on driving the loader up to
the truck and empty the bucket. See section 4.2.

The fourth bucket weight was so heavy that the total permitted load capacity of the truck
would be exceeded. The operator therefore does not dump the bucket load on the truck,
but shakes off some of the

material to reduce the weight to a suitable amount. The operator drives the loader to a
place where he can dump the superfluous material and presses to abort the
weighing. The LOADTRONIC II knows that the bucket has not been emptied and
immediately cancels the recorded weight and instead shows the current weight of the
bucket on the display. The operator shakes off some of the material until the display
shows that the weight of the material in the bucket is equal to what remains to be loaded.
The operator takes into account that the actual weight of the bucket load will be higher
when the bucket is tilted rearward and reweighed. When the bucket is fully tilted rearward
the operator reverses the machine, turns and drives up to the truck to empty the bucket.
While driving, the adjusted bucket load is weighed in the usual way by raising the bucket
evenly starting from below the horizontal level. The LOADTRONIC II is reactivated to carry
out a new weighing operation approx. 2 seconds after the gear selector was moved to
reverse. See section 3.3.
A new truck is already waiting. This time it is a customer which should be recorded
together with all data.

Issued 2005 - Copyright © AADI AS - All rights reserved

 OPERATOR’S INSTRUCTION MANUAL 58

The operator presses in order to:

>> Record the previous truck load
>> Begin to specify next load.

As he has pressed the truck key, the cursor is in the truck field on the display. The number
of this truck is 8 and he therefore presses .
The total weight (load capacity) for this truck has previously been given as slightly too high
and must therefore be adjusted a little. The operator presses to move the cursor to
the field for total weight. The total weight is changed by using / , or it can also be
typed in using the numeric keys.

He presses to move the cursor to the customer field.

It is customer no. 5, so the operator presses . Finally he selects the type of material by
pressing and the number of the material to be loaded. Thereby the record set-up is
completed. He checks that it is correct and then presses to prepare for loading.

The operator manages to load the truck without any hitches and after the last bucket is
delivered,
he presses to generate a load receipt printout. If there is no new truck waiting, he
presses to prepare for a new, unspecified load.

10.2. Material handling

The operator notices that the LOADTRONIC II shows the text “Adjust zero point”, as too
long a time has elapsed since the previous zero point adjustment. He therefore drives the
wheel loader onto ground which seems level. It is important that the machine also stands
horizontally sideways. While the machine is stationary the operator makes a manual zero
point adjustment according to the instructions in 7.4.

The stone crusher is designated as customer no. 2 and the material to be crushed is given
the designation no. 1. No truck is specified. The operator sets up the record for this and
begins to fetch material in order to take it up to the crusher.

Issued 2005 - Copyright © AADI AS - All rights reserved

51107 07/06 Issue #1
 OPERATOR’S INSTRUCTION MANUAL 59

He picks up the material with the machine facing down steeper than 10%. Under these
circumstances the machine operator will not raise the bucket to a height where the
LOADTRONIC II records the weight. The operator also knows that accuracy is often not so
good when weighing is done on a steep slope. Therefore he reverses up, turns the
machine and drives towards the crusher. On level ground the operator raises the bucket a
bit while driving so that the weighing operation begins. At the crusher the bucket is
emptied in the hopper while at the same time the operator checks that the bucket load has
been weighed.

Next time he does not raise the bucket while driving towards the crusher, but checks on
the display that weighing begins when the bucket is raised before the load is emptied in
the hopper. This method seems to work well and the operator continues in this way.

While taking a bucket load down the steep slope, the bucket was raised so high that the
weighing operation started. The operator however does not trust the result completely and
therefore presses when the machine is on level ground. This is to cause the bucket
load to be weighed again when the bucket is raised before the load is dumped.
By the lunch break the operator has completed the work of carrying material up to the
crusher and therefore presses to store the weight of the supplied material.

After the lunch break the operator has to carry the different grades of crushed material and
place them in separate heaps. The machine has then been stationary for a while and to be
on the safe side the operator first carries out a zero point adjustment.

Then he sets up the record using the correct material number and customer number 1, as
this is the designation given to the stock of ready material and then presses to begin
work.

The operator delivers the material by dumping it down a slope. In order to achieve an
accurate and safe weighing the bucket must first be raised fairly high before, +30° above
horizontal, it is tilted forward to dump the load.

 OPERATOR’S INSTRUCTION MANUAL 60

10.3. Loading with pallet fork

See also section 8.7. After having worked with the bucket, the wheel loader is to be used
for loading a truck with pallets. The machine operator therefore changes attachment and
fits the pallet fork. He also changes the attachment in the LOADTRONIC II by
pressing (or ) and , as 2 is the attachment number of the pallet fork.
See chapter 8.1.

The zero point should always be adjusted when changing attachment. The operator
therefore drives the machine onto level ground and makes sure that the machine is
standing horizontally, especially sideways. While the machine is stationary the operator
carries out a manual zero point adjustment according to the instructions in 7.4.
Then he drives the machine up to the first pallet, inserts the fork under it and raises it off
the ground. Then he reverses, turns and drives up towards the truck while at the same
time lifting the pallet higher. The LOADTRONIC II automatically weighs the pallet while the
machine is moving. The next pallet is positioned so that the operator after having lifted it
can continue driving forward. He therefore presses to activate the LOADTRONIC II.
Otherwise the gear selector must first be moved to reverse in order to trigger an automatic
weighing. The load is then weighed when it is lifted before being placed on the truck.

NOTE: Best possible accuracy is achieved if the pallet always rests against stop on the
pallet fork when the weighing commences.
