Abstract

1,153,399. Controlling winches. WELL. MAN MACHINES Ltd. 21 May, 1968 [25 May, 1967], No. 24300/67. Heading B8B. A hoist including four winding drums 11, 12, 13, 14 driven by two motors 15, 16 comprises a differential gear device 17 interposed between the drums and the motors whereby the relative rotation speeds thereof are consolidated normally to produce zero speed of an output shaft of the device 17, a switch being associated with the output shaft to cause application of drum brakes if the shaft does rotate due to a failure in the drive system. The drums 11, 12, 13, 14 are driven synchronously by the motors 15, 16 through gearing 18, 19, 20, 21, 22 and transmissions 24, 28 and 32, 36 from the drums 11, 14 and the motors 15, 16 are coupled to respective differential units of a pair within the device 17. The outputs from the said pair of units are taken from the pinion carriages thereof and mesh with a pair of input gears of a further differential unit having the output shaft secured to the pinion carriages thereof. The motors may or may not rotate synchronously. The device 17 which may be used in conjunction with various numbers of motors and drums may have the differential units replaced by epicyclic units.
