The crane incorporates an overload protection shut-off system. In the event of any
overload situation, however caused, the system prevents any further movement of the crane
boom, which will increase the load moment. This system allows movements, which reduce the
load moment and continued operation within the rated capacity of the crane.
An emergency stop button is located at the control position on the crane. In the event of
electrical failure, operation of two valves stops all functions except manual emergency control to
safely recover the load and stow the crane.
For further information on the operation and maintenance of the crane, refer to the
manufacturer's literature supplied.
