Advantages:

● Direct: Tensioner is applied directly to stretch the bolt, so We don't need to fight against friction or losses.

● Accurate: The applied load is controlled very accurately, because it is directly proportional to the pressure applied to the tensioner.

● Calculated: The load transfer factor is calculable, helping to give the correct residual load.

● Fast: Operation of tooling and improved accuracy reduces time required to tighten the load.

● Versatile: Tensioning allows for loading multiple fasteners in a joint at the same time, especially on the diagonal tensioning force balance to tighten simultaneously

● Reliable: Uniform bolt loading ensures a high level of accuracy by applying a consistent force.

● Stress-free: Purely axial, tensile loading ensures no torsional stresses are introduced.

 

 

Hydraulic bolt tensioner ( How it works by pictures)

State 1: Original state of bolt and nut before stretching, pay attention to the space between bolt length from top to the nut top, as you will see a clear comparison after the nut was screwed down.


State 2: The bolt tensioner is assembled on the top of the bolt, connect the bolt tensioner to a pump by a hydraulic hose.

 
State 3: Slowly operate the hydraulic pump, the hydraulic fluid power was transmitted to bolt tensioner cylinder part from the pump, exerting high pressure to pull the up level of the bolt. （Please make sure the amount of Torque you need by calculating the pressure, we have table for pressure and t torque ratio on the user manual, DO NOT OVERLOAD, it may damage your bolt, thread )

State 4: The bolt is pulled “thinner” by high pressure hydraulic force, then insert a tommy bar to the hole designed on the tensioner to screw the nut down to bottom of the bolt

State 5: Release the Pressure from the pump, and the bolt is locked tightly at the bottom of the bolt. ( WARNING: Please release the pressure from the pump first !!! DO NOT USE OTHER TOOL, i.e hammer, impact wrench to knock the tensioner, it is dangerous causing extremely high pressure oil leak, unnecessary injuries)


State 6: The nut touches the bottom of the bolt, remove the tensioner.


State 7: The bolt served as a “spring”, it is designed with certain tensile yield strength. When the hydraulic fluid force is released and tensioner is removed, the bolt is returned to“original thick”state, clamp and bite the nut with high tensile force.
