When overloaded, the machine feed is
automatically reduced using limit load control.
- Steering system
The machine has fully-tracked steering. When used
in conjunction with a pre-selection button, the
control lever allows the machine to be driven in four
different steering variations and the speed to be
changed at the same time:
- only front steered
- only rear steered
- coordinated front and rear-steered
- driving in crab steering
- Brakes: The machine brake consists of:
- the auto-inhibit of the hydrostatic drive
- the hydraulic spring accumulator brakes
integrated in the gears of all four drive units.
The machine brakes when the control lever is
swiveled back from the maximum position to
neutral. The accumulator or spring brakes are
activated both in the neutral position (during
machine “stop”) and when the engine is shut down
and they act as parking brakes.
During a towing procedure, the spring accumulator
brakes can be hydraulically disengaged by a
manual pump.
- Strut tower: The strut towers are secured to the
vehicle frame. The cold planer is lowered and
raised in a controlled manner into the position
required via these towers. Milling drum, connected
to mainframe, moves depending on the strut tower
movement. The strut tower movement can be
controlled manually or by the levelling system.
