Braking the uppercarriage The braking of the uppercarriage swing movements can be achieved via an hydraulic braking effect and also via a mechanical disc 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 key S17 a first time: the swing brake is switched in the automatic operating mode, the LED beside the key is out. If no swing movement is actuated via the joystick, and if at the same time the uppercarriage is at standstill or respec. if the swing speed is decreasing and approches standstill: the swing brake is applied, respec. it applies as soon as the uppercarriage speed passes under a given limit value. Caution! The brake only applies when the uppercarriage is near standstill. In order to stop the uppercarriage when working on a slope, first reduce the uppercarriage speed by braking with joystick 4. Move the joystick 4 back to neutral position only after the brake has applied. If a swing motion of the uppercarriage is actuated while the swing brake is applied: the swing brake is released. Depress the key S17 again: the swing brake is applied, the LED beside the key S17 illuminates.
Ermergency stop of the uppercarriage swing motion The swing brake can be applied independently of the uppercarriage RPM while switching the button S17 back to position «applied». Caution ! Only perform the braking via button S17 of the swinging uppercarriage as an exception, i. e. in emergency cases, since it causes fast abrasion of the brake discs.
To check the mechanical swing gear brake When the uppercarriage is stationary. Press the key S17: the mechanical swing brake is applied, the LED in the key S17 illuminates.
