Abstract
1366830 Food lifting apparatus SCHIESS AG 2 May 1972 [29 May 1971] 20280/72 Heading B8B A device for lifting and lowering loads on a platform 1 comprises a chain 12 secured at one end 15, passing around a sprocket 13 on the platform and over a chain wheel 9 into a storage pit 3, the chain wheel 9 being secured to a drive wheel 10 having ratchet teeth 11 thereon and being driven by successive strokes of an hydraulically actuated pawl pin 16 in combination with a retaining pin 31. The pawl pin 16, at each side of the wheel 10 pivotally connects the piston rods 17, 18 of a pair of hydraulic piston and cylinder units 19, 20 which are articulated to the bearing block 5 for the wheels 9 and 10, and the pawl pin 16 and the retaining pin 31 are spring biased radially inwardly of the wheels. During a load lifting operation the rods 17 are hydraulically extended from the units 19 to lift the pin 16 to rotate the wheels 9, 10 in the load lifting direction, the rods 18 of the units 20 being extended by this movement of the pin 16, and the retaining pin 31 riding over the teeth 11. After one stroke, the rods 17 are retracted and the pin 31 retains the wheel 10 in position pending the next lifting stroke. During load lowering, one or a pair of hydraulic piston and cylinder units 29 are operated to release the retaining pin 31 mounted in pivoted pawls 25, whereafter the rods 17 are retracted to permit the wheels 9, 10 to rotate in the load lowering direction. Upon full retraction of the rods 17, the retaining pin 31 is re-engaged the rods of the units 20 are extended to remove the pin 16 from the wheel 10, the rods 17 of the units 19 extended, the rods 18 are retracted and the pin 16 re-engages the teeth 11 ready for another lowering stroke. The sequence of operation of the piston and cylinder units is controlled by micro switches 32, 33, 34, 35, 36 actuated by the various moving parts, to control valves in the hydraulic circuit of the units. Several of these devices may be linked to the same load platform, with their control circuits coupled.
