OUTSIDE CUPPORTS FOR EXCAVATING WHEELS

摘要

The excavating and loading system includes an excavating wheel assembly at the front and conveyors from the excavating wheel assembly upwardly and rearwardly. The excavating wheel is wider than the overall width of the following portion of the system. A supporting and housing apparatus rotatably supports the excavating wheel and includes portions which engage the ends of the excavating wheel. The supporting and housing apparatus can be raised and lowered to adjust the excavating height of the excavating wheel assembly and thereby vary the grade of the excavating. The excavation wheel can positively move the walls of buckets between digging and dumping positions.
