Abstract

1371180 Crab-carrying telescopic jibs H LIEBHERR 10 July 1973 [26 July 1972] 32761/73 Heading B8B A crab-carrying jib comprises a fixed portion 1 and a telescoping portion 2. A load lifting crab 6 travels on rails 4 on the portion 1 through wheels 7 and on rails 5 on the portion 2 through wheels 8, the rails 5 being higher than the rails 4. When the crab 6 travels along the portion 1 the wheels 8, mounted on pivoted arms 9, are folded down into an inoperative position by springs (not shown). At the transition between the two jib portions 1, 2 guide tracks 11 transfer the wheels 8 between their inoperative and operative positions. When the crab 6 moves along the portion 2 the wheels 7 are disengaged completely.
