Abstract

1,202,599. Jib cranes. AUGUST BILSTEIN. 31 Oct., 1967 [11 Nov., 1966], No. 49495/67. Heading B8B. A crane jib comprises members 1 ... 5 which are telescopically movable by an hydraulic ram 8 and cables 14 ... 16 so that the respective speeds between the adjacent pairs of the members are the same, and a cable 7 extending round pulleys 17 ... 19 on the members 1, 2 and then directly to the member 5, the arrangement being such that the part of the cable 7 extending between the pulleys 17...19 and the member 5 changes in length during the telescopic movement by an amount substantially equal to and in the same sense as the change in spacing between the members 2, 5. The cable 7 is a jib retracting cable but in other embodiments is used as a hoist cable. It is preferably guided within the jib and may be replaced by a plurality of cables.
