Double acting hydraulic jack for building
The working principle of the high-voltage double acting hydraulic jack for building is based on Pascal’s law, that is, the pressure on a confined liquid can be transmitted in all directions without changing its magnitude. When an external force is applied, the force will be evenly transmitted to all parts of the container by the liquid. The mechanical energy is converted into the pressure energy of the liquid through the hydraulic pump, and then the pressure energy of the liquid is converted into mechanical energy through the hydraulic cylinder, thereby realizing the transmission and amplification of force.
High-voltage double acting hydraulic jacks for building are widely used in various occasions requiring large force output, such as construction, bridge maintenance, equipment lifting, etc. due to their high efficiency, stability and safety.

Double-acting hydraulic jack is a lifting device based on the Pascal principle, which is characterized by the ability to generate force during the rise and fall of the hydraulic cylinder. It is usually composed of hydraulic pumps, hydraulic cylinders, control valves and other components. The hydraulic pump is driven by electricity or manpower to convert mechanical energy into liquid pressure energy, and then the liquid pressure energy is converted into mechanical energy through the hydraulic cylinder, thereby achieving the lifting and lowering of heavy objects.

Application in the field of construction
