Hoist limit switch for Demag AC350/6

The hoist limit switch, identified by part number 23271012, is a safety component integrated into the lifting system of the crane. Its primary function is to monitor the position of the load block and prevent over-hoisting by automatically interrupting power to the hoist motor or engaging the brake when the maximum height is reached. This action prevents the hook from contacting the boom or trolley, which is essential for maintaining operational safety.

This component is specifically engineered for the Demag AC350/6 all-terrain crane. It is manufactured by Demag to meet the precise electrical and mechanical requirements of the crane's safety systems. The switch ensures accurate detection and immediate response during lifting operations, which is critical for preventing mechanical damage and ensuring the safety of the load and personnel.

Limit switches in crane systems act as automatic cut-off devices. By sensing the physical position of the hoist rope or block, they provide a signal to the machine's control system to halt movement before a two-blocking condition occurs. Proper installation and regular testing of these switches are necessary to ensure the continuous protection of the lifting equipment during its service life.
