ABSTRACT:
An excavator digs trenches by partial buckets on a vertical chain which is adjustable as to contact with the ground by two hydraulic cylinders. The excavator is built upon a frame having wheels, with the back wheels being driven by a hydraulic motor so that the vehicle creeps forward at a very slow speed. Excavated dirt is contained by the partial buckets in conjunction with a plate behind the buckets. The dirt is then transferred by means of troughs on the buckets to a belt which conveys it away from the trench.
