Abstract

1,005,003. Mobile collapsible jib cranes. KOEHRING CO. April 4, 1962, No. 12968/62. Heading B8B. In a mobile jib crane, having a jib composed of two parts 11, 22, Fig. 4, hinged together by an offset pivot 21 so that the two halves can be folded down parallel to each other, the jib is erected from the travelling position, Fig. 1, by a cable 50, Fig. 4, which passes round lever arms 53, 56 between the outer tip of the jib 30 and hoisting tackle 52, 72. To erect the jib, arms 41, 42, Fig. 1, are raised to the dotted line position and held there by pins 44. With a winding drum 85, Fig. 6, braked, the jib is raised to the position shown in Fig. 3 by a double winding drum 65, Fig. 6, which acts through sheaves 52, 72 on cables 50, 51. The arms 41, 42 are next pinned to the crane base at 118. So that the cable 64, Fig. 6, may be kept short, with a consequent reduction in the size and cost of the double drum 65, a smaller and cheaper drum 85 is used to wind in an interconnected cable 86, with the drum 65 running free, so that the sheave 72 is moved away from the sheave 52, compare Figs. 3, 4, ready for the next part of the erecting routine. The drum 85 is now braked and the jib part 22 is raised by the drum 65. Pivoting of the lever arms 53, 56 during the raising of jib 22 is such as to increase the moment arm as the jib approaches a horizontal position. The crane runs on a turntable 6 and outriggers 8, 9, Fig. 1, are provided. A welded construction is used with square section tubular chord members 23 and round section tubular lacing members 24. Specification 1,005,005 is referred to.
