Smarter bolting solutions for mining’s toughest conditions
When you’re working deep underground or across vast open-pit operations, every minute counts – and every connection matters. At Technofast, we design and manufacture precision-engineered bolt tensioning solutions that help mining operations across Australia and the globe reduce downtime, improve safety, and eliminate guesswork in high-stress applications.
Whether it’s critical joints on continuous miners or dragline boom assemblies, our hydraulic tensioning tools deliver fast, consistent results – even in the tightest of spaces.
Why mining teams choose Technofast
We’ve been working alongside heavy industry for nearly 30 years. Our tools are used every day by mine maintenance crews, OEMs and contractors across Australia, the USA, China and South Korea.
Here’s what makes Technofast different:
Built for confined spaces
Our EziTite® hydraulic bolts and nuts are designed to function reliably in the cramped, high-pressure environments typical of underground mining.
Faster installation times
With hydraulic power and direct preload application, you’ll spend less time tightening bolts and more time keeping machines operational.
Improved safety
By replacing manual slugging tools and torque multipliers, we help reduce common OH&S hazards like pinch points and strain injuries.
Vibration resistance
Our tensioning solutions provide accurate, repeatable preload that doesn’t shake loose – even under constant operation.
Custom-engineered solutions
Our in-house engineering team can design and model tensioners for specialised mining applications, using FEA, 3D CAD, and decades of experience.
Australian made, globally proven
We manufacture our products at our Brisbane headquarters and support mining operations across four continents.
Where Technofast fits in mining
Our hydraulic bolt tensioning tools are ideal for a wide range of mining equipment and applications, including:
- Underground continuous miners
- Crusher and mill assembly
- Conveyor systems
- Draglines and shovel booms
- Pump and motor mounting
- Structural joints and critical fasteners
In mining, traditional methods like torque wrenches and impact tools can be slow, imprecise, and dangerous, especially in low-access environments. Technofast solutions use direct hydraulic force to apply even tension across bolts, resulting in better performance and fewer failures.
Want a tool that fits your site’s specific layout or machinery? Our engineers can design custom tensioners to suit your exact specifications.
Site: Caledon Cook Colliery
Case study: CS-17 underground coal mine
Application: Bolting the cutter head to boom on an ABM continuous miner
Problem: Manual torque multipliers caused OH&S risks (pinch points), poor access, and unreliable bolt tension – leading to bolts vibrating loose in operation.
Solution: Technofast custom M42 EziTite® Hydraulic Bolts
Results:
- Install time reduced from 3.5 hours (with 2–3 personnel) to just 30 minutes (2 personnel)
- Safety improved by removing manual pinch-point tools
- No more vibration issues or bolt loosening during use
“The hydraulic bolts not only made installation faster – they also stopped the bolts from vibrating loose during operation, increasing uptime and safety underground.”

FAQs – Mining with Technofast
Yes. Our hydraulic bolts and tensioners are specifically engineered to work in tight, underground conditions with limited access and visibility. The compact size and ease of use make them ideal for coal, hard rock, and tunnelling operations.
By using hydraulic force instead of torque, our tools eliminate the need for slugging spanners and torque multipliers – two common sources of pinch-point and overexertion injuries.
Our products are used across draglines, continuous miners, crushers, conveyor systems, pumps, and structural assemblies – anywhere precise preload and fast turnaround matter.
Absolutely. We regularly work with mine sites to develop application-specific solutions. Our team can model and manufacture tensioners to suit your exact machine or structure, whether above or below ground.
Yes – all Technofast hydraulic tools are designed to work with standard hydraulic pumps and hose systems, meaning minimal changes or training required.
