Some Considerations on Optimal Placement of the Arm Hydraulic Cylinder to an Excavator

The development of hydraulic equipment is in the direction of increasing working pressures, increasing rotation speed and travel speeds, while ensuring satisfactory reliability and durability and reducing operating fluid losses. But, a high efficiency of the machine also implies a high-quality connection between the hydraulic and mechanical systems. A correct positioning of the hydraulic cylinders ensures the kinematic movement of the arms, boom and bucket. In addition, a correct positioning of the hydraulic cylinders implies the maximization of the heavy duty construction vehicles performance. In this sense, the arms excavators have a prolongation that permits the piston to have the extension stroke during digging. The length of this continuation of the arm must take account of the disadvantages of an oversized arm and of the advantage of reducing the force the cylinder must transmit. In order to highlight the importance of optimal cylinder positioning, in paper are analyzed the possibilities of placing the arm cylinder to an excavator.
