Overhaul ball for Grove RT522

The overhaul ball is a lifting accessory designed for connection to the crane's auxiliary hoist line. It provides the necessary weight to keep the wire rope taut when operating without a load, facilitating the attachment and detachment of slings, chains, or auxiliary hooks at the boom tip. This component is engineered for light to medium lifting tasks, providing an anchor point for rigging equipment.

This specific unit is compatible with the Grove RT522 rough-terrain crane. It features a maximum safe working load capacity of 4 tons. The assembly includes an eye or shackle for attachment to the crane cable and a hook mechanism at the lower section for securing loads.

In crane operations, an overhaul ball acts as a weight to ensure the hoist cable remains under tension during payout and retrieval. This prevents the cable from bird-nesting or tangling on the drum when the hook block is not in use. By maintaining consistent tension, the component supports the smooth operation of the auxiliary hoist system during various lifting configurations.
