Mechanical Tensioners

In a world of heavy industry, where large machines and equipment build and shape our world. No one should ever have to question the integrity of critical bolted connections. PRSverse mechanical nuts and bolts tensioners use the multi-jack principle for bolt tension. This is proven technology used for successful installations. Mechanical tensioners are easy to work with and provide a mechanical advantage with their unique design, which divides the load among multiple sm all jack bolts. Correctly installed, connections are reliable, stay tight indefinitely and disassemble easily for planned maintenance. Even the largest nut and bolts are safe and can be installed or removed by a single worker with ordinary hand tools. These solutions to solve the bolting challenges.
The pressure vessel is a one example where millions of mechanical tensioners are used to secure bolts on the critical applications.


Operating Principle

Mechanical tensioners are designed as direct replacements for conventional nuts and bolts. Mechanical tensioners can be replaced to a new or existing bolt, stud, threaded shaft. The main thread serves to position the tensioner on the bolt or stud against the hardened washer and the load-bearing surface. Once it is positioned, actual tensioning of the bolt or stud is accomplished with simple hand tools by applying the small torque to the jack bolts which encircle the main thread. The jack bolts transfer the preload evenly into the main thread and, consequently, onto the joint. The main thread is tightened in pure tension without any torque generation.


How It Works

By tightening the jack bolts, a heavy axial force is generated. This force is directed against a hardened washer. Jack bolts have a small friction diameter and can therefore create a high thrust force with relatively little torque input. The loads are transferred through the nut body which is positioned on the main thread by hand rotation.
A hardened washer is used to transfer the force while protecting the flange face. The axial force of jack bolts and the opposite reaction force of the main bolt head create a strong clamping force on the flange. The axial force from the jack bolt creates an equally strong reaction force in the main bolt. You can trust our products; we guarantee that our mechanical tensioner products will stay in place and fulfill their function for the entire lifetime of the bolted connection.
