Problems solved by technology

[0004] However, the oil ports of the rod chambers of the two drive cylinders of this system are only connected to one one-way back pressure valve; The two one-way back pressure valves are not connected; when the hydraulic oil flows in from port A of the balance valve, it flows through one of the drive cylinders and the one-way back pressure valve connected to the drive cylinder, and then flows from port B of the balance valve. The hydraulic oil cannot flow between the two drive cylind
