Abstract

1,104,157. Lifting devices. J. S. THOMSON. 28 Feb., 1966 [10 March, 1965], No. 10086/65. Heading B8B. In a derrick which may be luffed and slewed, the free ends of a single hoisting rope are wound on a winch drum 9 and the rest of the rope passes in two reaches over pulleys 9A to pulleys 5, round a load block 10 and up to pulleys 6 which are laterally spaced with respect to the boom 1. From here the rope passes over pulleys 7 to a snatch block 11, which may be attached either to the load block 10, as shown in full lines, or to a fixed point on the boom, as shown in chain-dotted lines 8A. The latter arrangement is suitable for light loads. A clamp 12 prevents the rope from moving along its own axis thereby preventing the load from swinging during slewing movements. One of the free ends of the rope may be attached to the winch instead of wound on it.
