Hydraulic Tensioner

Follow the narrative to see how small design choices affect everyday performance. In this video, we take a close look at the THDG Series Hydraulic Bolt Tensioner, built for critical bolting in confined turbine spaces. Watch how its compact, hardened design, automatic return mechanism, and dual-cylinder layout handle high-preload work in wind, steam, and gas turbines. We also show how it connects to hydraulic pumps for multi-bolt synchronous tensioning, and how it can be customized for real on-site conditions.
