  • Patent number: 8388023
    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 and which rests with one end on a pressure plate (18) arranged within the shank tube and interacts with the moving end with a spindle nut (25) arranged in the support tube, wherein the spindle nut comprises a locking collar (90) with at least two locking devices (107, 108, 109, 110) which interact with locking latches (103, 104, 105, 106) formed on the tube wall of the support tube in such a manner that, with a coaxial alignment of the spindle nut with the support tube, the spindle nut can be inserted, in an assembly rotational angle position, into the suppo

  • Patent number: 5006032
    Abstract: In mobile and steerable lifting and setting-down apparatus for large transportable receptacles, in order to ensure steerability of the apparatus not only in pulling operation, but also in backward pushing operation, steering arms are attached to be movable up and down to the wheel cradles carrying the running wheels, the steering arms being articulated by their free ends to a steering rod which is mounted to be movable rotationally about its axis. A central shaft is coupled to the steering rod to be relatively movable in the direction of the axis of the shaft. The central shaft is pivoted by its inner end by means of a pintle to a connecting piece which in turn is mounted on the large receptacle to be swingable about an axis parallel to the base of the receptacle. The articulation point for the central shaft on the connecting piece which is formed by the pintle is located laterally in alignment with the pivots of the two adjacent wheel cradles.
