Up-to-Date-technology CAN System

A single lever on the left side of the
steering column gives the operator fast,
easy control of speed and direction.
Push the lever forward to go forward,
pull it back for reverse. Travelling is
automatically changed from 1st stage
to given stage according to travel
speed and tractive effort. The operator
can select two kinds of automatic
modes (1st 4th, 2nd 4th).
These exclusive features contribute to
a step-up in productivity and reduction
of operators fatigue.

Ride control system (optional)

Ride control system functions such as shock absorbers gives smooth
operation without losing of the load even over a rough terrain condition.
Therefore the system allows faster travelling and improved safety and
productivity.

High-rigidity frames

2 Operating mode

This guard helps to prevent possible

damage from load material.

Front and rear frames are designed for

work in the toughest applications to
provide high rigidity for the power train
and loader equipment. The high-rigidity
frames, together with the reinforced
loader linkage, resist loading stress
and shock.

Battery master switch(Option)

Sealed loader linkage

Frame lock

A master switch disconnects the battery power

to protect the electrical system from excessive
electrical drainage.

Fully protected fitting and the sealed loader

linkage with dust seals and o-ring will extend
lubrication intervals remarkably.

Machine can be locked by this locking bar to

prevent movement during transportation.

Multi Function Transmission

Some of the Photos may include optional equipment.

The CUMMINS QSB6.7 electronic control engine

combines full-authority electronic controls with the
reliable performance. The combination of high
pressure common rail system and advanced incylinder combustion technology results in
increased power, improved transient response and
reduced fuel consumption. And the QSB6.7 used
advanced electronics controls to meet the
emission standards (EPA Tier3, EU StageIII-A )

The newly developed transmission control represents the beating heart of transmission. The hydraulic system
for gearshifts is working with proportional valves, which allows very precise control of the clutches. For each
gearchange, the control unit performs a monitoring function to ensure that the specified shift curve is
adhered to the range, and readjusts the shift pressure applied to the clutches accordingly. This results in
smooth gearshifts-even under the load-with no traction interruptions. This helps to avoid standstill of the
vehicle, sudden load changes and torque peaks under all conditions, for example application on steep terrain
with full load. In addition, there is the option for the driver to make gearshifts manually.
Improved Axle

Limited Slip Defferential in standard eqipment allows easy driving on variavle ground condition.
Self adjusting Brake which regulate the Disk clearance automatically can maintain optimum Brake performance.
Due to Improved internal Oil circuit, durabiliy of Axle is increased.

An ideal arrangement of component parts ensures easy access and convenience for maintenance.
Highly accessible engine compartment assures fast and efficient maintenance.

counterclockwise.

With the application of Chromium

Plated PIN, durability and precision
are improved and the life cycle
became longer.

It is now easier to change your

engine oil, coolant and hydraulic
oil with the remote drain port.

The hydraulic tank is located behind the cab to increase the

accessibility of hydraulic hoses and pipings.

The hydraulic oil check sight

gauge is installed on the side of the
hydraulic tank for the convenient
checks from ground level.

The transmission oil change port is

also located for with open
accessibility and comes with an
anti-vandalism lock for your
machine protection.
