Abstract
1301233 Pulley arrangements TITOVI ZAVODI LITOSTROJ 12 July 1971 32547/71 Heading B8B An arrangement for suspending a load beam 5 from a lifting mechanism or trolley frame 4 comprises four pairs of cables 21, 21<SP>1</SP> extending from a motor driven winding drum 1, over pulleys mounted on the frame 4 and pairs of cables extending downwardly and angularly towards each other to equally support the load beam 5 mid-way along each side thereof. The inner cables 21 on the drum 1 pass either directly or via reversing pulleys 16, 17 to pulleys 6, 7, 8, 9 mounted on the frame 4 in swivel housing 10, prior to passing over pulleys 20 disposed on the beam 5 on an axis perpendicular to the drum axis, the cables then returning up to the frame 4 from anchorage thereto. The outer cables 21<SP>1</SP> pass either directly or via reversing pulleys 15, 18 to pulleys 11, 12, 14 mounted on fixed axles on the frame 4, from which they pass to and around pulleys 20 on the beam 5 and disposed on an axis parallel to the drum 1. In another embodiment Figs. 2, 4 (not shown), the depending cables are anchored directly to the load beam.
