Zusammenfassung:	PURPOSE:To eliminate automatically the application of abnormal force to a bucketwheel, when the force is applied thereto, at the time of automatic driving of a reclaimer. CONSTITUTION:When the current value of a wheel hydraulic pump motor exceeds a reference level, boom rotation is temporarily stopped, while the rotation is, resumed when the current is not more than the reference level afterwards. When the number of wheel rotation is not more than a reference level, the rotation of boom is stopped, and even when it is not more than the reference level after a fixed period of time has passed, a wheel is elevated, and when it exceeds the reference level, the wheel is gradually lowered, and when it comes to an initial benchmark, the boom rotation is resumed. These two operations are combined together.
