Hollow Through-hole Jacks: These jacks have a central through-hole, allowing them to be used with steel strands or tie rods for prestressing tensioning, grouting testing, and cable laying tension control.
Electro-hydraulic Jacks: These jacks integrate a high-pressure electric pump station, enabling remote or automatic control. They are key equipment for automating large-scale engineering construction.
Compact Large-tonnage Jacks: These jacks feature a split design, with the pump station and lifting mechanism separate. They are suitable for maintenance work in extremely confined spaces such as nuclear power plants and tunnels.
Intelligent Jack Systems: These systems integrate pressure and displacement sensors. Through computer control, they achieve real-time monitoring of the lifting process and precise control of force and displacement. They are widely used in precision industrial installation and historical building relocation projects.
