Hydraulic Strand Jack System

    1. Hydraulic Control Cabinet

      Our electrical jacking control system can simultaneously control 20 sets of strand jacks. Each strand comes with a maximum capacity of 45 tons and a speed of 3m/h.

    1. Hydraulic Strand Jack

      The hydraulic strand jack can handle heavy loads horizontally, vertically and angularly. Compared with other hoisting equipment of the same capacity, it is more flexible and ideal for narrow operations.

The Guoxin hydraulic strand jack lifting system integrates lifting equipment and traction equipment. Operating speed and synchronization are also greatly improved compared to previous systems. Now, each strand jack in the standard set-up lifting system has an unmatched capacity of 800t and a lifting speed speed of up to 60m/h.

The control system of this hydraulic lifting device allows both local and remote control, while supporting single operation and combined operation as well. The use of a rewinder and related equipment can reduce down time in continuous operation and greatly extend the strand's lifespan.

In addition, for any suitable occasion, the strand jack lifting system can use a frame to allow the jack to connect to the structure through hooks, leading chains, or standard suspension equipment.
