Abstract
1,153,804. Hoisting blocks. A. W. VAN GILS, and W. J. G. STROLENBERG. 2 Feb., 1967 [2 Feb., 1966], No. 5154/67. Heading B8B. A hoisting block for use in moving a load from or on to a ship subjected to wave motion comprises a freely rotatable drum 15 to which a load cable 18 is secured, a winch 27 by which a constant torque is exerted on the drum 15 via an operating cable 20, in a direction to wind up the load cable 18, and a pawl arrangement 9 by which the drum 15 can be arrested. The block is suspended from a crane arm 1 by one or more hoisting cables 3. The latter pass around pulleys 7 in the block and have their ends attached at 10<SP>11</SP> to a pair of spaced plates 8 spring biased upwardly and slidable along guides 12 mounted on side plates 4 of the block. The load and operating cables 18, 20 are wound on opposite ends of the drum 15, such that pay out of the cable 18 causes winding on of the cable 20. The amount of cable 18 payed out is therefore indicated at 32 by the movement of the cable 20, the constant tension in the cable 20 being sufficient only to lift the unloaded hook 19 on the cable 18. In operation, the block is lowered by cables 3 for a load on the moving ship to engage the hook 19, the cables 18, 20 being kept taut by the winch 27 during rise and fall of the load with the ship. At maximum rise, the winch 27 is braked and with the cable 20 causing a pivoted cranked lever 33 around which it passes, to move the plates 8 down until pawls 9 thereon engage ratchet wheels 17 in the drum 15, the load is arrested. The block is then raised by cables 3, which due to their attachment to the plates 8, hold the same in their downward position to maintain the pawl engagement. As the block is raised therefore, the brake on the winch 27 can be released and slack in the cable 20 is taken up. When the load is set down, the load in the cables 3 is released and the pawls 9 move out of ratchet engagement by means of the spring 14, whereupon the drum 15 is free to rotate again. The pawl and ratchet engagement may be effected directly by a manual pull on a cable 40 attached to the lever 33. In the embodiment of Figs. 3, 4 (not shown) the sliding pawl plates are replaced by rotatable pawl plates.
