Brakesystem
Engine brake
Depending on setting of switches, the engine brake is available to
reduce wear of the brakes.
Service brakes
The service brake is operated hydraulically. All wheel axles are
provided with sealed, wet multi-disc brakes with external oil
cooler. The brake system and hydraulic system have a common
oil tank. The brake cooling system has a separate oil tank.
Parking brake
The parking brake is hydraulically operated with a spring-applied
disc brake. It acts on both the front axle and front bogie axle by
automatic activation of the differential lock in the dropbox.
Proximity Detection System (PDS), interface
The machine may be equipped with a positioning detection
system (PDS).
PDS detects objects and prevents the machine from running into
them using automatic control of the throttle and brakes.
In the event of a communication error, the machine may enter
protection mode and reduce the maximum speed to 10 km/h (6.2
mph).
Contact an authorized dealer for more information.
Haul Assist
The machine may be equipped with Haul Assist. The Haul Assist
functions can affect the machine's speed by regulating the throttle
application.
Steering system
The steering system is self-compensating, hydro-mechanical and
has a secondary steering function. A ground-dependent pump on
the dropbox allows the steering to function even if the engine
should stop.
Suspension
GHS (Gas Hydraulic Suspension)
The machine features GHS, Gas Hydraulic Suspension, on the
tractor unit's front axle. There are two hydraulic cylinders filled
with oil and nitrogen gas. The cylinders work both as springs and
shock absorbers.
Machines with GHS may lean sideways a little depending on the
individual wheel suspension and amount of fuel in the diesel tank.
Cab
The cab has an automatically controlled heating and ventilation
system with defroster system for the windows. Air conditioning is
standard. The cab has three emergency exits; the door and the
front side windows on the right and left side, which are broken with
the hammer in the cab if use of that evacuation route is necessary.
