Abstract

1363776 Telcscopic crane jibs LEO GOTTWALD KG 26 Jan 1972 [26 Jan 1971] 3713/72 Heading B8B A telescopic crane jib comprises four sections with spars 1a, 1b: 2a, 2b; 3a, 3b and 4a, 4b with their upper ends respectively rigidly connected by cross-braces 14, 11, 12, 13. Rollers, such as 35 and 32, or wear-plates (not shown), guide the sections during movement by hydraulic rams 42, 43, 44 connected (in various arrangements, Figs. 9, 12 (not shown)), between adjacent sections. In a modification the lowermost twin spar section 1a, 1b is replaced by a closed section (1c), Fig. 4 (not shown). The jib is mounted for luffing, by hydraulic rams 7, on a base 6.
