Abstract

22,704. Toplis, C. M. Oct. 5. Jib cranes.-Horizontal traverse of the load of a jib crane during luffing is approximately obtain d by passing the hoisting-rope r in three falls r<2>, r<3>, r<1> over movable and fixed pulleys a, b, carried by the jib and the crane structure respectively, and finally leading it to the hoisting-drum. The positions of the pulleys b and the pivot c of the jib are chosen so as to obtain this result. The number of falls in the hoisting-rope may be varied according to the positions of the parts band c.
