PRODUCT DETAILS

The operating principle is based on Pascal's law. After the control system is activated, the hydraulic pump station operates, pressurizing hydraulic oil into designated hydraulic cylinders. This high-pressure oil pushes the cylinder piston rods, which in turn drives the boom to raise, lower, and extend/retract. By controlling the flow and oil levels of various oil circuits, precise control of the crane's movements is achieved.
