Abstract

327,478. Toplis, C. M. Jan. 17, 1929. Jib cranes.-In a level-luffing crane as claimed in Specification 22704/12, the jib is balanced by a weight b<5> on a lever b pivoted at b<1> and connected with the jib at b<3> by a link b<4>, and the jib is luffed by a rotating crank e<1> connected with the lever b by a link e<3>. The dimensions may be chosen so that the lever b is always parallel with the jib.
