Custom Designs
Special Design
Our engineering staff utilise state of the art drawing and 3D modelling packages to design Technofast’s comprehensive range of unique hydraulic tensioning solutions.
Technofast’s unique digital approach to design allows all virtual models to be effectively assessed for performance before any prototypes are manufactured and tested. Finite Element Analysis is utilised daily, allowing our engineering team to run virtual experiments so that our engineering team can further optimise our custom solutions.
Our team has found this is an effective method, as it allows significant reductions in overall size of components. It’s also economical, as significant cost reductions can be achieved, resulting in savings for clients.
3D Printing
The introduction of 3D printing has exponentially changed how engineering teams design and verify engineered solutions on a daily basis.
To prove a design or to check fitment on an application, our Technofast team is able to utilise 3D printing technology. A custom solution can be printed and passed on so that users can verify the feel and fit of our proposed custom solution for their application.
It’s simple and effective.
Manufacturing
All components are produced in house using modern CNC machines, ensuring that exceptional quality is maintained throughout the manufacturing process. Certified alloy steels are typically used for these to ensure toughness and durability. Products can also be finished with a variety of surface treatments to suit environmental conditions.
Laser Marking & Dot Peen Marking
Laser & Dot Peen marking can be tailored to meet particular requirements. For example, it is ideal — from the smallest of tools through to larger tooling — to be maintained on equipment/asset registers, so on request extra markings such as the following can be added to your tools:
- Part numbers.
- Asset numbers.
- Special instruction.
- Serial numbers.
How does it work?
There are a number of different tooling designs using the basic hydraulic “direct tensioning” principle. Depending upon the application needs, these can take the form of:
- The hydraulic nut — where the item remains in place.
- A bolt tensioner — which applies the tensioning force but is subsequently removed from the job.
- Any number of tailored solutions including Technofast’s high temperature products, such as EziTite TR Hydraulic Nuts or CamNut Systems.
In all products, the hydraulic pressure is produced externally by standard pumping equipment and directed to create the ideal force specified to load the subject bolt to its ideal tension.
By using the Direct Tension method, operators can avoid over-tensioning bolts, avoid galling of threaded fasteners, and avoid the need for rework whilst improving the efficiency of the operation and offering much improved safety for operators.
For EziJac Bolt Tensioners, the operation is similar. The Bolt Tensioner is built as a tool of modular components and is removed from the job after the tensioning operation is complete.
Install the tool onto the bolt
First, install the EziJac bolt tensioner or EziTite nut onto the bolt and connect the hose.
Activate the Pump
Activate the pump so that hydraulic oil flows into the load cell.Load Generated
The load is generated within the sealed internal surface area of the tool or hydraulic nut and the force is transferred directly to the subject bolt. Lock The Nut
The nut rotator/lockring can then be engaged to mechanically lock the load onto the bolt.Release The Pressure
What are the benefits of using a Direct Tension hydraulic method?
It’s Safer
Eliminate physical exertion and keep your operators safe — they no longer need to use hammer tightening methods or hold torque tools in place during operation.
It’s Efficient
Eliminate physical exertion and keep your operators safe — they no longer need to use hammer tightening methods or hold torque tools in place during operation.
Less Physical Exertion
Technofast products use hydraulic pumps to generate bolt force, eliminating the need for physical labour and manual tightening. This thereby requires less physical exertion from your team and creates greater safety for your workers on-site. These products can prevent exertion-related injuries.
Better Accuracy
These products remove the need for repeated ‘star pattern’ tightening cycles needed for torque tensioning tools. Ideally, all bolts are tightened simultaneously from one pressure source. This allows a perfect balance of force across all bolts in the joint so that no bolt carries more or less load than others in the pattern.
