​The hydraulic lifting device for storage tank construction is a typical mechatronic integrated product, mainly composed of a pumping station, an operation console and a working mechanism. The pumping station includes electric motors, axial piston variable pumps, oil tanks, etc., providing the required pressure oil for the hydraulic lifting device of the storage tank construction.

The hydraulic cylinder is the core actuator of the hydraulic system. It drives the piston to move through the pressure of the oil, converting hydraulic energy into mechanical energy. Its core structure consists of four major parts that work precisely in coordination:

The hydraulic cylinder is composed of the main unit and the control mechanism. The main parts of the oil cylinder include the body, the master cylinder, the ejection cylinder and the liquid filling device.
