Post Groutable Hi-Ten Flexi Strand Cable Bolts

Key Features

• The Post Groutable HI-TEN is a high tensile and shear load capacity strand bolt. It is a cable designed to be installed as a long rock bolt which is capable of being post-tensioned at the face, or out-bye, to loads of up to 25 tonnes using the DSI Underground Tensioner Unit.
• The Post Groutable HI-TEN Strand Bolt is manufactured from 21 wire strands having a 12mm square, for mixing resin anchors, welded to one end of the strand and is available in lengths up to 10 metres.
• The Post Groutable HI-TEN Strand Bolt has a special collar and segmented wedge, which can sustain collar loads of between 52 and 55 tonnes.
• The Post Groutable HI-TEN Strand Bolt concept allows a longer than seam height bolt to be installed at up to 30° from the vertical at the face, or out-bye, to supplement existing strata reinforcement. Compatible domed plates are available to be used with the Post Groutable HI-TEN Strand Bolt.
• The bolt can be post grouted immediately or at any time later using standard grouting equipment.
• Provides very efficient anchorage at the very top end of the bolt using a unique combination of a spiral resin mixer and a bulb. The bulb is always fully filled with 100% mixed resin.
• Anchorage strength of the resin grouted top end of the bolt exceeds bolt tensile strength in typical rock conditions.
• The Post Groutable HI-TEN Strand Bolt system is patent pending.
