Abstract

1,127,532. Winches. BRITISH HOIST & CRANE CO. Ltd. 19 Dec., 1966 [4 Dec., 1965], No. 51543/65. Heading B8B. A friction driven winch comprises a winch drum 1 freely rotatable in bearings 2 in a neutral position and movable between a first position in which the drum 1 is connected to a drive shaft 4, and a second position in which the drum is connected to a braking mechanism 5. The drum shaft 9 is movable by an hydraulic piston and cylinder arrangement 7 under the control of an hydraulic valve 14. The latter is normally actuated manually between an " up " condition in which the drum 1 is driven to elevate a hoist coupled thereto, a " neutral " condition in which free fall of the hoist occurs, and a " stop " condition in which the drum is braked. The valve 14 is biased to the " stop " condition. This manual operation of the valve 14 is overridden by a valve 21 which when electrically operated, switches the valve 14 into the " stop " condition. The electrical valve 21 is operated by trip switches 32, 33 which limit the travel of the hoist, or may also be operated by trip switches 30 at intermediate hoist stations depending on whether they are selected to operate via selector 31. The drive shaft 4 having drive wheels 3 is driven via gearing 6 by a petrol engine. In another embodiment, the drive shaft is driven by an electric motor.
