Send the working conditions with your inquiry. The team can discuss the jack, hydraulic power supply and matching components together.

Apply pressure to the cable?

Please provide details on the strand layout, required tension, travel, and anchorage.

Should you lift or push a structure?

Share the load at each point, number of points, movement, closed height and available space.

Does it need to be compatible with the existing hydraulic pump?

Please provide its pressure, flow rate, control method, and connection type, as well as the on-site power supply conditions.
