Hydraulic bolt tensioners are widely used in various industries, especially in energy industries such as wind, nuclear, thermal and hydropower. Hydraulic bolt tensioners pre-tighten bolts to a predetermined tensile force by generating high-pressure liquid force, thereby achieving a safe and reliable fixing effect.

In the wind power industry, the blades and other components of a wind turbine are primarily connected by bolts. Since wind turbines often face high-speed rotation and wind impact, bolted fasteners are susceptible to vibration and stress, so they need to be regularly inspected and re-preloaded. Hydraulic bolt tensioners can precisely control the preload force of bolts, ensuring a secure and reliable connection of bolts, reducing the risk of loosening and breaking.

In the power industry, such as nuclear, thermal and hydropower, a large number of bolted equipment and mechanical components are used. Due to the high requirements for the stability and reliability of bolted connections due to the operating environment and working conditions of power equipment, the application of hydraulic bolt tensioners can ensure that the bolted connections do not loosen or break during operation, thereby ensuring the safe and stable operation of the equipment.
