Me invention relates to a lift for people and Laetenbsfcröerung, with articulation en the boom eires hydrßuliöch operated excavator.

For the construction of tunnels, the blasted rock is removed with hydraulic excavators. For work on the stone carcass, scaffolding must be set up, from which, for example, rock drills are operated by an operator.

The invention is based on the object to transport the Rock required excavators to equip by simple measures in such a way that fixed scaffolding by a Lifting platform to be attached to the standard device and operated by the existing hydraulic device replaced v / earth.

This object is achieved according to the invention in that the lifting platform is attached to the free end of the upper boom part in a pivot point and at the free end of a linkage

“AD ORIGINAL

is articulated in a pivot point, the linkage with your boom top and the pivot point in oineia can be pivoted supported triangular link forms a parallelogram, and that in a pivot point on the triangular link and in one Pivot point at the Stütsbocl: parallel to the GruKäausleger one another linkage is attached.

The advantage of the arrangement according to the invention is that that the lift is attached to a standard serial excavator and thereby achieves great mobility will.

In the drawing, an embodiment of the erfinaungsgeraäßeii arrangement is shown. On the superstructure 1 one on caterpillars 2 mobile. Excavator, which is usually used for earthworks or in quarries, etc., the normal base boom 3 is pivotably articulated in the pivot point At of the block 1 a and is actuated by the hydraulic cylinder 5. The upper part 6 of the jib is detachably attached to the basic jib 3. At the free end of the upper boom part 6, the lifting platform 7 is articulated in the pivot point 8, in a further pivot point 9 arranged on the lifting platform 7, a linkage 10 is pivoted, the other end of which is pivoted in the wishbone 11 at the pivot point 12.

The wishbone 11 is in the pivot point 13 on the main boom 3 hinged. In the pivot point 14, a linkage 15 is articulated, which is articulated in the pivot point 16 in the bracket 1a is..

The procedure is as follows;

If the operator wants to enter the lift 7, because from there work, z «. B, in a tunnel the stone face should be executed, we-! the stage by means of the main boom 3 and the prescribed Linkage lowered so far that the lift 7 touches down on the subgrade. To get the man to work the operator of the excavator only needs the hydraulic lift with the ones on the excavator To lift devices and, if necessary, to pivot about the pivot axis 17 of the superstructure 1. In addition, as soon as the pivoting movements are insufficient, the whole vehicle can still go to work be driven up.
