Advantage of Hydraulic Bolt Stretcher

Our hydraulic bolt stretcher can quickly and safely synchronously stretch bolts. They can apply force to each bolt evenly and permanently. If the bolt is not properly stretched, it will not work properly. For the connection combination, accurate stretching combination is the key. Hydraulic bolt tensioner reduces this risk. Precise calculation of preload can avoid [...]
