Abstract

706,041. Lifting attachments for breakdown cranes. TAYLOR & SONS (MANCHESTER), Ltd., F. July 17, 1952 [July 17, 1951], No. 16893/51. Classes 78 (3) and 78 (4) A load handling platform x is raised and lowered in guides t by luffing movement of a hydraulically actuated jib a. The platform side arms n are connected to the jib by rods o, and a stirrup member q which engages a notch n<SP>2</SP> in the arms n; rollers s being provided on the rods o to co-operate with channel section guides t during lifting movements. The platform is adapted to be stowed in a collapsed position (shown chain dotted), beneath the jib, where it is retained by catches v, whilst on release of these catches upward movement of the jib effects re-engagement of stirrup q with notch n<SP>2</SP> ; rollers s which together with rollers s<SP>2</SP> on the stirrup, engage a horizontal guide s<SP>1</SP>, facilitate this return of the members o, q and x to an operative position. The jib carries sling engaging hooks k, k<SP>1</SP> and an eye m, and its end position a<SP>1</SP> is hinged at i. The device is stated to be particularly suitable for use as a breakdown crane. In a modification (not shown), the guides t are replaced by guide links.
