Machine description

Diesel engine

The machine is equipped with a water-cooled, straight four
cylinder, four-stroke, turbocharged diesel engine with direct
injection and a charge air cooler

Electrical system

The machine has the following control units.
• Electronic Control Unit (ECU)
• Engine control module (ECM)
• Main display

Propulsion/Transmission system

The propulsion system is a hydrostatic system with a hydraulic
pump supplying two motors connected in parallel, one for the
rear axle and one for the drum.
The speed of the machine is proportional to the angle of the
control lever (the deflection of the forward/reverse lever
regulates the speed). A speed selector system is available.

Brake system

The brake system comprises a service brake, secondary brake
and parking brake. The service brake system produces
retardation of the propulsion system, i.e. hydrostatic braking.

Secondary and parking brake

The secondary and parking brake system comprises spring disc
brakes on the rear axle and the drum gear which are disengaged
by hydraulic pressure.

Steering system

The steering system is a hydrostatic system. The control valve
on the steering column distributes the flow to the steering
cylinders at the articulated joint. The steering angle is
proportional to the amount the steering wheel is turned.
