ABSTRACT:
Lifting and depositing devices for transportable large containers should be dismountable into individual parts of relatively low weight per part for simplification of their handling. So that this is also true of relatively long overhang arms of the rack and pinion jacks of such devices, each overhang arm is configured generally in the shape of a wrench having a narrow middle part and forked end parts, and is of generally flat construction, so that its greatest structural height corresponds only approximately to the structural height of the winch assembly. The overhang arms thus have a relatively narrow, lightweight middle portion and because of the flat construction following dismounting of the winch assembly and support legs they have the desired light weight per piece.
