LIFTING HOOKS
Cranston’s lifting hooks are designed specifically for top attachment lifting and are most commonly hung from multiple spreader bars or lifting frames. All Cranston hooks are manually attached to the lifting strap and then once in the unloading location, depending on the model, can either be removed or unlocked manually and or pneumatically from a remote location (typically with a manual striker plate or electric solenoid). All items in this product line are designed for outdoor maritime use. Acceptable applications can be multiple strands of wire, wire ropes, steel rings, fabric slings, or flat steel slings. All must be carefully reviewed and tested.

Since then, the capabilities and uses of these products whether dockside or in a warehouse have flourished.
