3 TECHNICAL DATA

3.1 Technical description

The loader consists of the vehicle frame, the drive and the axles. The vehicle frame contains all the drive and control units for the standard conguration. The vehicle frame consists of the front carriage with the loader lift arms, and the rear carriage, in which the drive unit is situated. They are connected by an articulated swivel joint.

Drive

The loader is driven by a diesel engine, which powers the steering and working hydraulics and the driving hydraulics.

The propulsion hydraulics provide power to the transfer gear box by a directly attached hydraulic motor. The rear axle is integral with the transfer gear box. The front axle is powered by a driveshaft connecting the transfer gear box to the front axle.

The axles are designed as rigid axles.

Brakes

Service braking is provided by the propulsion hydraulic system through the transfer gearbox and driveshaft to both axles. The braking-inching pedal provides a secondary service brake by contacting a hub-mounted differential in the transfer gear box. A separate parking brake with separate control is provided that engages the differential hub in the transfer gear box.

Steering

The fully hydraulic articulated swivel steering system operates via a dual action cylinder.

TE CH N IC A L D ATA

Hydraulics

The loader has two hydraulic systems supplied by a hy-

draulic uid reservoir:

- hydrostatic drive

- steering and working hydraulics

The hydrostatic drive consists of an axial piston variable displacement pump, which drives an axial piston motor. The axial piston variable displacement pump is rigid coupled directly to the diesel engine, while the axial piston motor is directly coupled to the transfer case.

Displacement is automatic and continuous, but depends on speed and load. The travel speed depends on the engine speed and the machine load. Operating speed is set by the accelerator pedal position, engine speed and torque demand of the loading operation. Depending on load, the variable displacement pump automatically adjusts pump displacement to balance torque and speed requirements within the power capability of the diesel engine. Since the

input power is limited to the diesel engine output, increased demands from traversing a grade or loading the bucket will result in speed reduction which increases the torque to meet the performance demand. This adjustment control allows the entire range of performance to be utilized optimally. Actuating the inching pedal is an override control that can reduce wheel loader speed as operation demands. Depressing the pedal to the full range will stop the travel motion

of the wheel loader. The inching pedal permits an innite

number of control positions. The inching pedal provides the

service brake function by destroking the pump until no uid

is transmitted between the pump and motor.

A gear hydraulic pump supplies the steering and working hydraulics with oil. The gear pump is rigid coupled to the

drive‘s variable displacement pump. Pump ow output is

directly proportional to the diesel engine speed.

The hydraulic system is equipped with relief valves, lters

and oil coolers.

TE CH N IC A L D ATA

W L 3 0

Electrical system

The electrical system operates at 12 volts and the electrical circuits are protected by fuses to prevent overload damage to the system and its components.

Equipment

The loading equipment consists of the loader lift arms with an integrated mechanical or hydraulic quick-change receptacle, lifting and tipping cylinders and the appropriate attachments.

The loader is equipped with a rollover protective structure (ROPS).
