Excavator with automatic cycling

An excavator device with a bucket which can be rotated frictionally and is guided on a constrained path from the digging point to the emptying point by the common movement of two arms. Quick emptying is effected by forcible deceleration of the stroke movement in the emptying direction, a counterweight being accelerated at the same time which alleviates the reaction on the carrier vehicle (Fig. 2). The strain on the driver is relieved and the excavator capacity is increased by automatic cycling.
