摘要:
Emergency hand crank drive consisting of a load shaft that is to be made to rotate, and a crank arm hingedly connected to said load shaft, and a coupling piece on said load shaft and a catch, which is fixedly connected to said crank arm and which has a shape that is complementary to the shape of said coupling piece and which can be releasably connected to said coupling piece, whereby a rotary sliding piece is mounted on said load shaft in such a way as to be movable in the longitudinal direction of said load shaft and be rotatable around the longitudinal direction thereof and said crank arm is hingedly secured to said rotary sliding piece.
摘要:
The invention relates to a support (2) for supporting and compensating a shift in the position of a parked semi-trailer (1), which support consists of an outer support tube (21) and an inner support (22), which can be telescopically slid into the outer support tube (21) and consists of a support upper part (221) and a support lower part (222), said parts being hinged together by a pivot bearing (23), wherein the lower end of the support lower part (222) is rigidly connected to a rolling segment (24) and the outer surface of the outer support tube (21) is fully closed at least along the edge facing the inner support (22), and wherein the rolling segment (24) has a dished shape and in the retracted state of the support (2) the outer support tube (21) protrudes into the rolling segment (24).
摘要:
Vertical elongate support (2) for supporting a parked vehicle trailer (1), consisting of a top prop tube (21), an inner prop member (22) which can telescopically slide into the prop tube (21), and a threaded spindle (3) for moving the inner prop member (22) in relation to the prop tube (21), whereby the threaded spindle (3) meshes with a threaded bearing (31) that is secured to the upper end of the inner prop member (22). The upper end of the threaded spindle (3) is connected to a crown wheel (32), the upward-facing surface of which is part of a thrust bearing (33) or is designed to accommodate a thrust bearing (33). The thrust bearing (33) supports the vehicle trailer (1), either directly or via a cover (23) that is connected to the prop tube (21).
