Abstract: A foot device (29) for supporting a support device or lifting device, in particular a semitrailer support or the like, comprising a foot receptacle (31) for connecting a pivoting foot (32) to a support tube (12) of the lifting device (10), wherein the foot receptacle comprises an insertion body (120) for insertion into the support tube, comprising, in two support tube engagement areas spaced apart from one another by a spindle passage area (143) of a lifting spindle (20), bracket receptacles (123,124) for receiving pivoting brackets (130,131) of the pivoting foot, wherein the pivoting brackets are connected in a captive manner to the insertion body along a pivoting axis (136), and the bracket receptacles comprise counter support faces (133) which are arranged concentrically with respect to the pivoting axis and which, for transmitting the supporting forces, correspond with respective support faces (132) formed by the outer contour of the pivoting brackets.

Abstract: The invention relates to a lifting device (10), in particular a semitrailer support or the like, comprising a shank tube (11) and a support tube (12) which is movable with respect to the shank tube, wherein on the shank tube a lifting gear mechanism (26) is arranged which comprises an input shaft arrangement (27) for connecting a drive device and an output shaft arrangement (28) for driving a lifting spindle (20) which is arranged within the support tube, wherein the input shaft arrangement and the output shaft arrangement each comprise at least one large-diameter gearwheel (70, 80) and one small-diameter gearwheel (62, 81) which can be put in force-fitting engagement with one another to generate different transmission ratios, wherein the input shaft arrangement comprises a hollow shaft (86) supported in a gear housing (68), and an axially movable gearshift shaft (85) which is arranged coaxially with respect to the hollow shaft and which is supported in the gear housing, wherein the hollow shaft serves for th
