Abstract

1341206 Winding apparatus CLARKE CHAPMAN - JOHN THOMPSON Ltd 3 Nov 1971 [3 Nov 1970 10 Nov 1970] 52204/70 and 53452/70 Heading B8B A drive means for a pair of rope drums 11, 12 of an overhead trolley crane is formed as a closed kinematic chain including normally unloaded gear-wheels 26, 27 between gear-wheels 13, 14 rotatably secured to the drums 11, 12, the gear-wheel 27 being mounted so as to be displaceable perpendicularly to a diametrical plane including the points of contact between the wheels 26, 27, 16 and a warning device being operated upon displacement of the gear-wheel 27 when the gear 27 has a torque load applied thereto due to a failure in the normal drive path within the kinematic chain. Each drum 11, 12 is normally driven from a respective motor 17, 21 through reduction gearing 18, 22 and through pinions 20, 24 engaging the gear-wheels 15, 16, the motors 17, 21 being interconnected by a shaft 25. The displaceable gear-wheel 27 has its shaft mounted either in a slot or in a deformable bush, the said movement of the wheel 27 causing its shaft to operate a limit switch 35 to energize a visual or audible warning signal device 36, the gear-wheel 27 remaining in mesh with the adjacent gears during such displacement. Braking devices 28, 29, 30, 31 are provided in the transmission system.
