Abstract

264,769. Eisenwerk vorm. Nagel & Kaemp Akt.-Ges., and Koch, C. B. Oct. 26, 1926. Jib cranes.-To ensure approximately horizontal travel of the load in luffing, the hoisting rope O is passed over a single compensating pulley k which slides in guides i on the rear part of the jib under the control of a rope l anchored at n and passing over a sheave or step-pulley m on the tail of the jib. The jib is luffed by a motor h and screwed rod, chain, or rope g.
