Hydraulic sliding cab, function description
The cab can be moved forward to facilitate access for service and
maintenance in the engine compartment.
Hydraulic cab movement (sliding cab) also means that the cab can
be moved hydraulically during operation to improve operator's visi-
bility. The cab is pulled forward and backward by a hydraulic motor
that is connected to a chain secured in the cab undercarriage. The
cab's position is blocked automatically by the hydraulic motor when
cab movement is not in use.
Damping
Damping means that the speed of functions is reduced automatical-
ly near the end-positions. This results in less stress on the mechan-
ical parts when stopping in the end-positions.
Position sensors sense when damping should be activated. When
damping is activated, the control unit in question reduces the con-
trol current to the solenoid valve for that function.
