JACK

  〓 PRODUCT FEATURES  

The hydraulic cylinder is made of chrome-molybdenum steel, resistant to high pressure (above 80MPa), and the stroke can be customized;

Equipped with high-precision sensors, the error is ≤1%, and it supports synchronous tensioning;

Lightweight design, suitable for narrow spaces.

  〓 MAIN PURPOSE  

Precisely control the tensioning force through the hydraulic system to achieve graded loading and load holding.

  〓 APPLICATION SCENARIOS  

Cable force adjustment of cable-stayed bridges, segmented tensioning of prefabricated box girders, and reinforcement of large-span steel structures.

  〓 INSTALLATION POINTS  

Carry out a no-load operation test before tensioning to ensure that the coaxiality error between the jack and the anchor is less than 1°;

After the oil pipe is connected, the air must be exhausted, and the pressure and elongation must be monitored in real time during the tensioning process.

Structural safety Intelligent tensioning eliminates human errors, ensures uniform distribution of prestress, and prevents bridge cracking and deformation	Efficient advancement Multi-equipment collaboration and automated operation shorten the construction period of large-span, multi-channel bridges.	Full-scenario coverage From coastal corrosive environments to extremely cold plateaus, the equipment can output stably, reducing engineering restrictions.	Low maintenance cost Highly durable materials and processes significantly extend the service life of bridges and reduce later maintenance investment
