The upper run of the caterpillar track is guided by support rollers (2). The
lower run of the caterpillar track runs over track rollers (4) with a swinging
movement.
Each caterpillar track is tensioned by a guide wheel unit (5). On starting the
drive motor, the chains are tensioned automatically and relieved of tension
again when this is switched off.
Steering
The steering is activated electronically. Sensors send steering signals to the
hydraulic control unit of the travel drives. The steering movement results
from different speeds of rotation of both track undercarriages.
Travel drive and brake system
The track undercarriage is equipped with parking brake and service brake
systems that operate independently of one another. The parking brake
secures the parked machine on a slope. The service brake is used for
deceleration during operation, and prevents the machine from accelerating
inadvertently when traveling downhill.
The service brake functions by hydraulic control or blocking of the travel
drives. The parking brake is an oil bath multi-disk brake.
