It uses the hands and feet linkage operation, through electric motor impetus hydraulic pump to main feed circuit , use the overflow valve, control valves and manual cross valve according to each kind of active status. This hydraulic system framework is compact, movement keen reliable, the speed is quick, the energy consumption is small, the noise is low, the pressure and the traveling schedule may adjust willfully in the stipulation scope, the operation is simple. In this design, through the consult massive literature material, has designed the hydraulic cylinder size, has drafted the hydraulic pressure schematic diagram. According to the pressure and the current capacity size choose the hydraulic pump, the electric motor, the control valve, hydraulic pressure parts, the auxiliary part and filter.
