High Tension Hydraulic Bolt Tensioner  

The JOBA Bolt Tensioner is an accurate, fast, simple, safe and multi-combination bolt tensioner. It stretches the bolts through an ultra-high hydraulic system to achieve precise demand loads. After the bolt is stretched, turn the nut down to maintain the load, then decompress and release the pressure, and then proceed to the next step. Hydraulic bolt tensioners are used for pre-tightening and dismantling of various high-strength bolts. The biggest feature is that the bolt pre-tightening precision is high, Cable Bolt Tensioner and multiple bolts can be pre-tightened at the same time, and the pre-tightening force is uniform. Hydratight Bolt Tensioning is an ideal tool for synchronous pre-tightening of bolts in large-scale processing machines, petrochemical equipment, power equipment, chemical synthesis tower covers and metallurgy, mining, automobiles, large diesel engines, etc.Bolt Tensioning Equipment Product Description  …
