Weight and chain assembly for Grove

The weight and chain assembly functions as a mechanical trigger for the Anti-Two Block system on Grove cranes. By hanging from the boom tip, the weight and chain assembly monitors the position of the load block relative to the boom head. When the load block rises too close to the boom tip, it lifts the weight, which releases the tension on the A2B switch. This action signals the crane control system to stop hoist and boom extension functions, preventing the load block from contacting the boom structure.

This component is compatible with various Grove crane models equipped with an Anti-Two Block system. The assembly includes the necessary weight, chain, and clamp required for installation on the hoist line or boom tip. Proper installation ensures the weight hangs freely to maintain the sensitivity of the safety system.

Anti-Two Block systems are standard safety features on mobile cranes designed to prevent mechanical damage to the boom, wire rope, and load block. The weight and chain assembly acts as the physical interface that detects the proximity of the hook. Regular inspection of these components ensures the system remains responsive during lifting operations.
