Product Description
Intelligent tensioning jack is ahydraulic device matched with intelligent tensioning instrument and used for bridge anchor tensioning construction. This kind of jack integrates pressure, displacement and other sensors, which can be connected to the tensioning instrument to achieve automatic tensioning. The tensioning data is recorded in real-time, ensuring that the tensioning process is controlled. And it is widely used in anchor tensioning construction in railway, highway, and high-speed railway bridge engineering.
