Abstract
A grapple 1 comprises a sleeve 8 moveable along a shaft 12. The sleeve 7 is joined to an upper attachment 6 for receiving the long-line of a crane, and the shaft 12 is joined to a pivot attachment 13. The sleeve 7 and the pivot attachment 13 are joined to jaws 2 and 3 which can move in a scissor-like fashion. Pushing down on the sleeve 7 causes a rider 9, forming part of a catch rod 8, to move into a series of stepped channels in a block 14 associated with the shaft 12. The rider 9 can be positioned in the channels to lock the jaws 2 and 3 open, and can be subsequently removed from the channels to enable the jaws 2 and 3 to close towards one another.
