This brake is capable of dynamic operation and has
sufficient holding capability to cause major damage to the
Boom and Swing Machinery in the event that it is applied
suddenly. For this reason, caution is urged in the use of
this brake for stopping the swing motion.
The method described below using the swing control lever
to control the swing is the preferred method of stopping
the crane. However, do not abruptly engage the control
lever in the opposite direction.
