Cable Bolt Bulbed 15.2mm

• Description
• Parameters

• Cable Bolts for Mining are used for temporary and semi-permanent rock reinforcement in underground Mining. Rock bolting with prestressing steel cable bolts combines low bolt weight with high load-bearing capacity. The system remains flexible even with larger cable bolt lengths.

  Special Mining Cable Bolts featuring a free length or a threaded anchorage instead of the default barrel and wedge system were developed for challenging ground control works. These bolts allow a tensioning of the system without tensioners.

  Key Features

  1.     Manufactured from stress relieved, low relaxation, high strength 15.2mm diameter 7 wire steel strand, the cable bolt is formed by bulbing the strand into small cages, typically 26 to 28mm diameter, and up to 6 bulbs per metre.

  2.     The cable bolt bulbs can be modified, in frequency and diameter, so that geotechnical engineers are able to design specific reinforcement products to suit ground conditions being encountered. In some cases, de-bonding tube can be added to the lower section of the bolt to allow for pre-tensioning.

  3.     The bulbed cable bolt is supplied in either single, double or in combination forms. Single bulbed plus single plain cable. They are supplied in nominated lengths for grouting into holes from 35mm to 105mm diameter.

  4.     Can be used with cementitious grouts as well as resin anchors when early support is required.

  5.     For up hole applications, cable bolts are fitted with a spring wire "fish hook" to hold the cable bolt up the hole.

  6.     Surface confinement is provided by flat or domed plates and barrel and wedge anchors. Please refer to appropriate pages for slotted or multiple hole plates, barrel and wedge anchors, grout and breather tubes.
