Top Side Hydraulic Bolt Tensioners

A torsion-free bolt elongation process ensures a galling-free and damage-free workspace, delivering safer and more reliable operations. With Hydrotorc’s Top Side Hydraulic Bolt Tensioners (TBTs), heavy-duty bolt tensioning tasks can be performed with precision and efficiency.

Unlike torque wrenches, which introduce torsional stresses, TBTs apply a purely axial tensile load, eliminating the risk of twisting or thread damage. Their detachable, rotating bridge design allows for easy positioning and improved accessibility in complex applications.

The applied load is highly accurate, as it is directly proportional to the hydraulic pressure supplied to the tensioner. Built with high-strength puller bars and dependable load cells, these tensioners are engineered to handle a wide range of stud sizes while ensuring maximum safety, repeatability, and performance.
