Adjustment of K-brake type K8
The air gap (S) should be between 1.0 and 1.5 mm and is set by adjusting the nuts (3) equally
while the brake is energized.
The distance ring (5) for the respective brake torque – according to the crane data sheet –
should always be fitted.
The maximum brake torque is obtained by turning the adjusting nut (12) up against the ring
(5). If required, the brake torque can be reduced by loosening the adjusting nut (12), thus
releasing the compression of the spring (11).
When used as a slewing brake, the adjusting nut (12) must be loosened when the crane is out
of service to allow the jib to weather-vane.
The internal parts of the brake are greased with light ball bearing grease before leaving the
works. It is advisable to keep these parts well greased.
