Hydraulic system
Swivel unit brake
Hydraulic swivel unit brake:
The upper carriage's rotation is sufficiently braked by moving control lever 29 back to initial
position. Moving the control lever in the opposite direction (counteraction) brakes the
upper carriage with maximum hydraulic output.
Mechanical stop brake:
A multidisc brake integrated in the rotation drive has an additional mechanical brake effect
with time delay. This negative-effect brake is used as a stop brake and parking brake for
the swivel unit. The upper carriage can be stopped in any position.
Notice!
Do not use the brake as a service brake but only as a stop brake and parking
brake for the swivel unit.
