<p>FIELD: transport. ^ SUBSTANCE: base for carrying or lifting device resting, specifically semitrailer support, contains support aperture for joining pivoting foot with support tube of lifting device. Support aperture contains plug-in element intended to be inserted into support tube and having holding hollows to be joined with swivel fingers of pivoting foot. The hollows are located in two zones of joint with support tube which zones are separated form each other by lifting rod stroke zone. The swivel fingers are inseparably connected along swiveling axis with plug-in element, and holding hollows have counter-support surfaces located concentrically with the swiveling axis. These surfaces are joined with corresponding support surfaces formed by outer contour of swivel fingers. ^ EFFECT: increase in structural height of lifting device. ^ 8 cl, 6 dwg</p> |
