Abstract
A suspension grapple adapted especially for use in transferring nuclear fuel assemblies to a reactor core, a fuel pool and the like. It includes a hook swingable into and out of engagement with the fuel assembly, a first lock mechanism for automatically locking the hook in lifting engagement with the fuel assembly, and a remotely operable mechanism for disabling the first lick mechanism to disengage the hook from the assembly. A second lock mechanism is provided to lock the hook out of engagement with the fuel assembly. The grapple further includes an automatic release mechanism which operates to release the hook from that out-of-engagement position and move it into lifting engagement with the fuel assembly upon the grapple abutting the assembly in a predetermined positional relationship therebetween when being lowered to engage the assembly.
