Cranstons lifting hooks are designed specifically for top attachment lifting and are most commonly hung from multiple spreader bars or lifting frames. All Cranston hook's 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. Please contact us to have a sales representative contact you to discuss your needs.

This kit includes one each load hook, load hook pin with set screws, latch, latch spring and latch pin. These corrosion resistant parts enhance hook maintenance and are preferred for general use. This hook and latch are the standard supply on all new 3MT Uni-Hook models except 26A092. This kit is the factory substitute for the following obsolete parts:
