Cable Bolts

Natural movement in rock strata can threaten a safe work environment. Our Cable Bolts are designed to perform despite lateral strata movement.

Cable Bolts incorporate much higher strength than traditional bolts with incomparable flexibility to adjust to the movement of the earth’s strata.

Cable Bolts KLW Type

Cable bolts are made from cable of Ø15.5 or 18 mm in diameter and 1+6 structure. Upper end is cut by one side to perforate resin cartridges easier. Upper part cable was modified to achieve better load distribution on resin column around cable. When filled up with grout or resin the cages act like stiff bulbs in relation to the cement face.

Birdcages are designed to mix resin cartridges. In the lower part there is stiffening tube and tensioning sleeve. Both items are solid jointed. Tensioning sleeve with the wedge work as clamp. Bottom is ended with hexagonal adapter to rotate the bolt. Rubber seal on the cable used only when installed with the resin of low viscosity.

The following production options are available:

  • KLW 15.5
  • KLW 18
  • KLW 15.5 z
  • KLW 18 z

Cable Bolts KL 18 and KL 18 K

Cable bolts are made from cable of Ø18 mm and 1+6 structure in accordance with PN-71/M-80236 standard. The following types of bolt can be distinguished:

  • Cable KL 18 (Plain cable)
  • Cable KL 18 K (Bird cage cable bolt)

The cable lay of KL 18 K bolt was modified to form birdcage like bulbs of 100 mm in length and 26 ÷ 28 mm in diameter. This ensures a better force distribution affecting the cement grout around the cable. When filled with grout the cages act like stiff bulbs in relation to the cement face.
