Machine description
hydraulic pump supplies all motors with hydraulic oil.
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 is available as option.
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/Parking brake
The secondary and parking brake system comprises
sprung disc brakes to each drum, drum half
respectively wheel pair.The disc brakes are
disengaged by hydraulic pressure.
Steering system
The steering system is a hydrostatic system. The
steering wheel is connected to a steering valve that
distributes the flow to the steering cylinders at the
articulated joint. A hydraulic pump supplies the
steering valve with oil.
The steering angle is proportional to the amount the
steering wheel is turned.
In some markets, the machine is also equipped with
an emergency steering system, either manually or
electro-hydraulically.
Vibration system
The vibration system is a hydrostatic system in which
a hydraulic motor drives the eccentric shaft, which
generates the drum's vibrations.
An eccentric shaft in the front-resp. rear drum
generates the the drum's vibrations.
Each eccentric shaft is driven by a hydraulic motor. A
hydraulic pump supplies each hydraulic motor with oil.
High amplitude/low frequency or low amplitude/high
frequency is controlled by the direction of rotation of
the hydraulic motor.
