*How it works

Hydraulic transmission is the use of closed systems in the pressure of liquid to transfer motion and power A type of transmission. It converts the mechanical energy into the pressure energy of the liquid, and then Converts the pressure energy of a liquid into mechanical energy. The pistons of a large syringe are pushed by hand.The rod, which transmits energy through the piston to the water, the pressure of the water can be passed through the small syringe.The piston rod transmits to the arm rod and the excavator, and converts into mechanical energy of the arm rod and the excavator,implement the corresponding action.
