Anti-two block switch for Grove RT-175

The anti-two block switch 7598100004 is a safety component installed on the boom of industrial cranes. Its primary function is to detect the proximity of the crane hook or load block to the boom head, preventing a two-block condition where the load block strikes the boom structure. When this condition is detected, the switch signals the crane control system to interrupt hoisting or boom extension movements, thereby protecting the equipment from structural damage and preventing wire rope failure. This component is essential for maintaining safe lifting operations, particularly in environments with limited visibility or confined spaces.

This part is compatible with various rough-terrain crane models, including the Grove RT-175, RT-650E, RT-87, RT-875, RT-875E, and T-650E, as well as corresponding models from P&H and Terex. It is designed to function within the crane's boom assembly to monitor the position of the load line. Regular inspection and functional testing of this switch are required to ensure the crane's safety systems operate as intended during daily lifting tasks.

Anti-two block switches act as limit sensors that provide feedback to the crane operator and the load moment indicator system. By monitoring the distance between the hook and the boom tip, these switches help prevent accidents caused by over-hoisting.
