Crane Smart anti-two block system for Link-Belt HTC 1060

The Crane Smart anti-two block system serves as a safety device designed to monitor the distance between the hook block and the boom head. By detecting the proximity of the load handling equipment to the boom tip, the system manages the crane's lifting and boom extension functions to prevent a two-block condition. This integration into the crane's control architecture provides automated intervention to stop movement before contact occurs between the hook block and the boom assembly.

This specific unit is configured for the Link-Belt HTC 1060 hydraulic crane. The system utilizes a sensor mounted at the boom tip that transmits signals to the crane's control unit, triggering audible and visual alerts in the operator cab while simultaneously locking out functions that could lead to contact. Regular inspection and testing of the sensor and control interface are necessary to maintain the operational integrity of the safety system on this model.

Anti-two block systems function by creating a circuit that is interrupted or triggered when the hook block reaches a pre-determined limit. This signal forces the crane's control valves to close or the hoist motor to stop, effectively halting the upward travel of the hook or the extension of the boom to protect the structural components of the crane from damage.
