Product Introduction
The HS Series Hydraulic Bolt Tensioners are manufactured from high-quality alloy steel and are available with maximum operating pressures of 80 MPa or 150 MPa.
The tensioners are designed for use with an ultra-high-pressure hand pump or electric hydraulic pump together with high-pressure hydraulic hoses.
They are suitable for the tensioning and removal of large bolts and are widely used in equipment assembly, installation, and maintenance in industries such as chemical processing, metallurgy, power generation, cement, shipbuilding, coal mining, machinery manufacturing, and pressure vessels.
