Abstract

1,141,228. Winches. INDUSTRIAL ENG. Ltd. 11 Dec., 1967 [9 Dec., 1966], No. 56145/67. Heading B8B. A hoist winch drive mechanism for a crane having a main and an auxiliary hoist winch drum comprises two hydraulic motors constantly drive coupled together, and a clutch 47, 50 associated with each drum 45 to drive couple it to the motors, the motors being energizable separately or together. The two drums, one of which is shown in Fig. 2, are identical and have their shafts 34 driven by hydraulic motors 37 drive coupled together via a chain passing around a sprocket 30 on one end of each shaft 34. The drum 45 is freely rotatably mounted at 46 on the shaft 34 and is clutched thereto by a surface 47 integral with the drum and engaging a friction band 50 mounted on a carrier 51 splined to the shaft 34. An hydraulic cylinder 55 effects engagement of the clutch, and the clutches of the two drums are interlocked such that only one engages at a time. Brakes associated with each drum are interlocked with the clutch such that either the clutches or the brakes are operating. Each motor 37 drives the shaft 34 through a reduction'gear 39, 41, 35 and is capable of delivering half the maximum torque required for hoisting, the other half being delivered by the other motor which is automatically energized when necessary.
