Hardy Prometheus

 Hardy Prometheus

 

Hardy Prometheus expandable rock bolts offer superior quality that respond to the most demanding roof support applications. Hardy Prometheus’s high load capacity along with excellent elongation properties ensure safer working conditions and faster excavation cycles, effectively reducing costs. The system consists of a tubular steel bolts, which have been folded inward along its entire length to reduce their diameter, a tool for installation and a water injection pump at high pressure

Application

Hardy Prometheus are recommended for rock support in mining, tunnelling and civil engineering application, where a rock reinforcement of underground excavations and temporary ground control is needed

Features

  • Friction bolt with faceplate inserted, adjusted and expanded into the drill hole
  • Case at the top of the friction bolt with hole to inflate the bolt pressure water
  • Full view of the friction bolt
  • Face plate at the top of the friction bolt: no nuts necessary
  • Hardy Prometheus bolt also available with corrosion coating

 Hardy Prometheus

Steadfast Anchors

Steadfast Anchors

 

The self-drilling hollow bar anchor system is comprised of a hollow threaded bar with an attached drill bit that can perform drilling, anchoring and grouting in a single operation. The hollow bar allows air and water to freely pass through the bar during drilling to remove debris and then allow grout to be injected immediately after drilling is completed. Grout fills the hollow bar and completely covers the entire bolt. Couplers can be used to join hollow bars and extend the bolt length while nuts and plates are used to provide the required tension.

Steadfast Anchors

Advantages

  • Safe, reliable and time saving
  • Simple installation and operation process
  • Anchor bars can be cut in any length as per customer demand
  • It provides higher bounding stress than smooth steel pips
  • Suitable for difficult ground conditions
  • Choice of drill bits for different ground conditions

Resilient Heracles

Resilient Heracles

Resilient Heracles is a friction stabilizer system and is commonly referred to as Resilient Heracles or Split Set design is used to firmly control hard or soft rock of underground Mining. As lateral ground movement increases, the system increases its superior holding power. Friction rock bolts produce superior holding power due to their unique design that exerts pressure against the rock over its full contact length immediately upon installation. When a ground shift occurs, our rock bolt conforms to the changing ground conditions. The result is a tight grip that actually grows stronger with time and ground movements, providing reliable ground support. An added advantage is that these friction bolts never needs tightening. The radial compression of the slotted steel tube inside the bore hole provides both radial and axial restraint to the rock movement.

Resilient Heracles

Advantages

  • Fast and easy installation
  • Reduced bolting costs
  • Yieldable support
  • Immediate load-bearing capacity after installation
  • No mixing and no pressurizing

  • Maintains plates pressure
  • No torquing or retorquing
  • Loads rock in compression
