Braking the uppercarriage

The machine is equipped as well with an hydraulic as with a mechanical swing brake. The hydraulic swing brake

Let the left joystick 4 move back to neutral position. The hydraulically swing braking of the uppercarriage takes place. In normal working conditions, the braking efficiency is sufficient to bring the uppercarriage to a standstill rapidly.

Move the left joystick 4 in the opposite direction. The maximum hydraulic braking action of the uppercarriage is achieved. The mechanical swing brake

The mechanical brake is a negatively acting multidisc brake which is integrated in the swing gear. It allows to stop the uppercarriage in any desired position (for parking, when working on a slope, ...).

Press the touch S17. the red LED beside the touch is lighting. the swing brake is applied.
