The excavator arm consists of four primary structures: the base, the boom, the dipper, and the bucket. It is modeled from the Caterpillar 320C excavator reference dimensions shown to the right (found online). For simplification, all structural components and linkages were specified as ASTM A36 with a total system weight of 8,040 lbs (not including hydraulic fluid weight contribution).
