Abstract

1282075 Lifting tongs COMMISSARIAT A L'ENERGIE ATOMIQUE 19 April 1971 [24 Feb 1970] 22601/71 Heading B8H [Also in Divisions B5 and G6] Self-locking tongs 109, used for example in detaching cuttings made in a nuclear fuel element can during a decanning operation, are formed of a curved jaw 110 on which is hinged, on a pivot 111, a straight lever 112 with an eccentrically shaped end 113 which, on rotation of the lever, locks the end of the can 6 which is to be detached between the end 113 and a needle 114 set in the jaw 110. The other end of the lever 112 contains a hole 115, engaged by appropriate hoisting means. A locking device 116 enables the lever 112 to be kept closed on to the can.
