Abstract

' The jib 1 of a jib-crane is luffed by a cable 17 which extends between a yoke 13 pivoted to the top of the jib and a pivoted lever 18 on the base. The lever 18 is turned about its pivot by a winch 10 and cable 11. A hoisting cable 9 passes from a winch 8 over pulleys 15, 14 on the yoke, round a load block 21 and terminates at the outer end of the yoke. Fig. 3 (not shown) illustrates an embodiment in which the yoke is of inverted L-shape.
