PCT No. PCT/DE95/00332 Sec. 371 Date Oct. 11, 1996 Sec. 102(e) Date Oct. 11, 1996 PCT Filed Mar. 10, 1995 PCT Pub. No. WO95/28368 PCT Pub. Date Oct. 26, 1995The invention relates to a mobile device for working and/or moving heaps, preferably stacked in the manner of an embankment, of compostable materials (ricks) or of materials which are suitable for a landfill, comprising travelling gear which can be moved on two tracks, an implement which can be driven in a rotating fashion essentially transversely with respect to the direction of travel within the space between the tracks of the travelling gear, and two clearing apparatuses which are mounted in front of the two tracks of the travelling gear in the direction of travel. Furthermore, the invention relates to a clearing apparatus for clearing material on a track of a mobile device. The invention is based on the object of developing a device and an associated clearing apparatus of the aforesaid generic type in such a way that they can be realized in a particularly compact fashion. The object is achieved according to the invention in that each clearing apparatus comprises a clearing blade which can be pivoted from a position pointing approximately in the direction of travel into the space between the tracks into a position approximately transverse with respect to the direction of travel and can be simultaneously raised automatically by an adjustment angle.
