The Direct Axial Tensioning of the Bolt or Stud has some unique advantages that remove the challenges:
- Residual torsional forces
- Friction related problems ...
Simple in construction, the hydraulic bolt tensioners provide a very high tensioning force to lengthen a bolt. The stretched bolt causes a gap to form and this can be used to tighten the nut in a new position.
The assembly of the components on the stud is easy. Tritorc's hydraulic tensioning tools that can be customized according to the Customer's requirement.
The factors such as the following are considered while modifying the tool:
- Inter-nut distance
- The pitch circle diameter of the flange
- The free space height available above the nut
High pressure bolted joints can be thus fastened together by overcoming the residual load with a trouble free operation.
The various types of hydraulic bolt tensioning tools are designed and built as per Industry requirements for a variety of applications. The variants include the following:
- Hydraulic Top Side Bolt Tensioners
- Spring Return Hydraulic Bolt Tensioners
- Multi Stage Tensioners
The tensioner can be assembled on the varied stud sizes and bolt loads in restricted spaces and high tensioning loads.
The Spring Return Tensioners use a return mechanism to allow for rapid tensioning operations and dismantling. Here, the hydraulic tensioner loads the cell piston to the original position quickly.
The two features that help the hydraulic bolt tightening machine to sustain high hydraulic pressure without load loss:
- The high strength puller bar made with heat treated special steel alloy
- Reliable load cell with its purpose built high performance seals
Additionally, a cycle counter to keep track of the tensioning cycles carried out using the particular tool. These assist with understanding the usage of the tool and the maintenance required to keep this tool in optimum condition. Using a Tommy Bar remains a reliable and proven option.
Several features such as the following make the tool resilient and easy to use:
- Zinc Flake Coating to ensure corrosion resistance
- Heat treatment and accurate machining to ensure a long life of the tool
- A strap handle to allow for easy tool lifting
- An eye bolt for lifting heavier variants makes the tool easy to carry.
- Optional Gear Drive for use of Manual Torque Wrenches
