Abstract
PURPOSE: To increase the tortional rigidity of the arm of a horizontal push type hydraulic shovel as well as to reduce the weight of the arm by providing a close structure with a concavity for the arm in such a way as to avoid the collision of the level cylinder and the arm cylinder of the shovel.
CONSTITUTION: The arm 28 of a bucket horizontal push type hydraulic shovel, having a close structure using upper, lower, and outside plates, is provided with a concaved portion 31 on its down side to which a level cylinder 9 and an arm cylinder are attached in such a way as to avoid their mutual collision. Also, the distance between the fitting point 14 of the boom of the level cylinder 9 and the rotary support point 10 of the arm 28 is made shorter than that between the arm fitting point 15 of the level cylinder 9 and the rotary fulcrum point 10 of the arm. Also, the boom fitting point 14 of the level cylinder 9 is positioned backwards from the vertical position of the arm 28 and also fforwards from the connecting line between the arm fitting point 15 of the level cylinder 9 and the rotary fulcrum point 10 of the arm.
