ABSTRACT:
The invention concerns a planing device for planing down road surfaces, having a roller-type, rotatably supported planing body designed in the form of a conveyor worm 3, the planing body having a multiplicity of planing tools which are arranged in releasable retention boxes 1 which are in turn bolted by means of their shank parts 4 in radial recesses 2, open at the side, it being possible to fasten at least one retention block 8 at least partially covering the shank part 4 by bolts 9 penetrating through the conveyor worm 3 in order to retain the shank part 4 of the retention box 1 in the side opening 2.
In order to change the retention boxes, it is then only necessary to loosen the fastening bolts 9 of the retention block 8.
