In the drawing is an embodiment of the invention and is explained in more detail below. Show it:

Fig. 1 is a vertical section through a tail lift

with releasably fixed axle body in clamp bracket square basic cross-section, on u / elchem the lifting and folding device is attached to the platform,

Fig. 2 is a side view, in an enlarged view, one in relation to the axle body cross-section diagonally split clamp holder and

3 shows a view of the same clamp holder rotated by 90,

A tail lift 1 according to the invention is a platform 2 on, carried by a handlebar parallelogram 3 and by means of at least one lifting cylinder 4 opposite the cargo space a truck, container or the like. And floor can be moved in height (can be lowered and raised) and by means of a lock cylinder 5 by one on a lifting arm of each handlebar parallelogram 3 provided horizontal axis 6 is foldable.

This lifting and folding device (items 3-5) is attached to an axle body 7 running transversely to the direction of travel, possibly also accommodating / supporting a hydraulic unit (not shown), which has a polygonal, in particular square (preferably square) basic cross-section and is in two clamp holders 8 which are held at a lateral distance from one another and are diagonally divided in terms of cross-section and which in turn are fastened to a vehicle chassis 9, in particular each to a chassis longitudinal member.

As can be seen from Fig. 2, the axle body 7 is in particular Executed as a square and held so that its upper and lower cross-sectional edges are horizontal and the bracket parting line 10 under 45 run to it. Each of the two clamp holders 8 consists of one in the upper and one in the direction of travel encompassing the front axle beam cross-section of the square (Overlapping) upper receiving part (clamp holder element) 8a with right-angled V-like axle body receptacle 11 as well as from one the lower and in the direction of travel rear axle body cross-section square side encompassing (underlying) lower receiving part / clamp holder element 8b with right-angled V-shaped axle body mount 12. These interacting parts (clamp holder elements) 8a, 8b are held together by means of connecting screws 13 and designed such that between the same there is also a larger manufacturing tolerance and a gap which always ensures that the axle body is clamped.

The upper receiving part / clamp holder element 8a of each clamp holder 8 also serves to fasten the clamp holder to the vehicle chassis 9. This is also referred to as a "U-piece" Axle body receptacle 11 has an upwardly protruding connecting flange 14 which is connected to a chassis longitudinal member screwed and / or welded (preferably welded) is / is.

The or the vehicle chassis 9. The like. Connectable / connected Receiving part / clamp holder element 8a is preferably in Executed welded construction and has a with one end angled / bent outwards, the connecting screws 13 female legs (V legs or L legs) formed V-piece made of thicker material, which forms the axle body receptacle numbered 11, wherein a thin-walled sheet metal at one end of the profile as a connecting flange 14 is welded on, which is kept stiffened (braced) with respect to the V-piece.

By connecting flange 14 expands upwards and u / eist at least one support strut formed out of the sheet metal material, in particular formed by fold (s) 15, 16 on. In a preferred manner, these “support struts” 15, 16 are made of an L-profile in the material cross-section Edge area folds are formed, preferably converging towards the bottom in the relative position to one another intended.

In this preferred V-shaped arrangement, one support strut 15 runs as an extension of one alignment aid contact surface 17 forming parting joint side U-leg surface of the clamp profile and the other (second) support strut 16 to to the middle area of the vertical V-leg of the same clamp profile. These support strut bevels are with the In the axial direction of the axle body, longer (thicker in material thickness) V-profile is welded.

The upper edge 18 of the connecting flange 14 runs parallel to the upper transverse edge of the axle beam cross-section and forms a further contact surface for an alignment aid, e.g. for a spirit level.

The lower bracket element / axle body-Aufnähme part 8b is preferably also made of welded construction. It consists of a V-piece that forms the axle body receptacle 12 ius sheet metal with angled (L-shaped) material cross-section V-legs (clamping legs) as well as in each case in the free end area these V-legs arranged - preferably used and welded - screw receiving parts 19 made of thick material.

is equivalent to. As a result, for both axle body mountings 11, 12 largely identical parts are used and the result is even more advantageous production and storage.

Although the illustrated and described clamp holder design is particularly easy to manufacture and advantageous, other embodiments of the invention are also possible. Furthermore, the axle body in the clamping area can also have a rectangular or other, diagonal division of the clamp mount allow polygonal cross-section.

The clamp holder-Trenafuge 10 can also ver 1 open from the front upper to the rear lower cross-sectional corner of the axle body.
