MANUAL CRANK ASSEMBLY FOR WINCHES, ESPECIALLY FOR RACK AND PINION JACKS OF A LIFTING AND DEPOSITING DEVICE FOR PORTABLE BOX-LIKE ARTICLES, E.G., LARGE CONTAINERS

摘要

ABSTRACT OF THE DISCLOSUREWith a lifting and depositing device for portablebox-like articles, in order to be able to operate their rackand pinion jacks manually and with ease by crank assemblies,each crank assembly has a haft-like crankcase, which has atone end a rotatable crankshaft and at the other end arotatable drive shaft, which can be connected with anadjacent rack and pinion jack having a winch housing. Thecrankshaft and drive shaft are operatively connected witheach other so that the latter is driven by the former. Thecrankcase can be connected with an adjacent winch housingand be pivoted into different work positions as well asfixed in such positions on the winch housing. Thus, theoperation of the rack and pinion jacks is especially sim-implified in their top and bottom end positions on theuprights of the lifting and depositing device.
