Machine description
Diesel engine
The machine is equipped with a water-cooled, straight
three cylinder, four-stroke, turbocharged diesel engine.
Electrical system
The machine has the following control units (ECU,
Electronic Control Unit) and electronic units.
• Main ECU (for the machine)
Propulsion system/Transmission
The propulsion system is a hydrostatic system with a
hydraulic pump supplying two motors connected in
parallel.
The motors drive the front and rear drums.
The speed of the machine is proportional to the
deflection/angle of the control lever from neutral.
Brake system
The brake system consists of a service brake,
secondary brake and parking brake.
The service brake is hydrostatisc and is activated by
moving the control lever to neutral.
Secondary/Parking brake
The secondary and parking brake system consists of
sprung multiple disc brakes in the motors. The brakes
are released with hydraulic pressure and are operated
with a switch on the instrument panel.
Steering system
The steering system is a hydrostatic system.
The control value on the steering column distributes
the flow to the control cylinder, which actuates the
articulation.
The steering angle is proportional to the deflection of
the steering wheel.
ROPS
ROPS is the abbreviation for "Roll Over Protective
Structure".
If any part of the ROPS structure's protective
construction displays plastic deformation or cracks, the
ROPS structure must be replaced immediately.
Never perform unauthorized modifications on the
ROPS structure without first having discussed the
modification with Dynapac's production unit. Dynapac
