Its wide application played a tremendous role to reducing the volume of labor and to ensuring project quality and to accelerating progress and to increasing productivity. Backhoe working devices is made up of a moving arm and a fighting pole and shovel and a hydraulic tank of moving arm and a hydraulic tank of fighting pole and a hydraulic tank of shovel. Based on the hydraulic excavator backhoe device characteristics and the structure of principle , to all the major institutions of the kinematic analysis . On this basis , in accordance with the design specification design requirements , with the bodies of the characteristics and design requirements , in terms of the various agencies at the same time , combining elements of known size parameters , calculated in the component agencies of other parameters , for various components , The shape of design data support. Mining is a measure of the ability of excavators digging the important parameters. Mining is done by the hydraulic cylinder of the pressure on the oil , is initiative , the largest excavation of the realization by many factors , it is also working device to hinge point Analysis of the foundatio
