Hydraulic Bolt Tensioner (228kN - 4650kN) (1519mm2 - 31000mm2)

Hydraulic torque pump is the power unit of a hydraulic wrench. Hydraulic tensioner pump is the power unit of a bolt tensioner. It is an energy conversion device that converts mechanical energy into fluid pressure energy, and is an energy device that provides pressure oil to the hydraulic transmission system.A hydraulic bolt tensioning tool provides a quick and easy method for tightening large diameter bolts to high and accurate pre-loads. Unlike conventional methods it does not use torque and does not require any forceful turning of the nut or bolt, like impact wrenches, flogging spanners or hydraulic torque wrenches.
