Shackles are sometimes substituted with inferior or improperly sized shackles in the field, compromising the integrity of a wire rope sling assembly. To avoid this, The Crosby Group, Tulsa, Okla., has introduced the Crosby Locking Thimble System, featuring the G-414SL Locking Thimble. The G-414SL Locking Thimble System uses a thimble designed with a lock mechanism that prohibits removal of the shackle when properly applied.
The Crosby G-414SL Locking Thimble provides several advantages due to its simplistic, patented locking design. Once a Crosby shackle and the G-414SL thimble are combined, the locking system keeps the “sling set” intact, by preventing the removal of the shackle. This assures the assembly is not compromised in the field, and the rated integrity and compliance standards are maintained.
The G-414SL Locking Thimble can be used across a broad range of industries, and is ideal for use on DNV 2.7-1 Offshore Container slings. Efficiency, costs and time associated with installation in the field are improved because the product is preassembled. Wire rope is not compromised by exposure to the high temperatures of welding because no welding is required due to preassembly of sling. The need for special fittings is eliminated with the Crosby G-414SL Locking Thimble System as it uses standard, off-the-shelf Crosby shackles.
