ABSTRACT:
Level data indicative of levels of the surface of a dump of refuse in pit are stored for each unit area into level data memory. An angle of an inclination of the refuse dump is obtained by using the level data in a unit area and the level data in unit areas adjacent to it. The inclination angle is compared with an angle of repose of the refuse dump. When the inclination angle is larger than the angle of repose, it is judged that the level data is improper. The level data as judged to be improper is altered so that the inclination angle is below the repose angle. The crane is controlled on the basis of the level data stored in the level data memory.
