Jennmar design and make all sizes FRICTION LOK STABLIZER for mining industry.

  → Friction-Loc stabilizer can be used in a variety of ground conditions for immediate ground support, but is not suitable for very soft strata and permanent support.
  → Friction-Loc stabilizer is a kind of yieldable bolt. It can be used in fractured/squeezing strata conditions of dynamic stress.
  → It is recommended to use the Friction-Loc stabilizer in entry rib support but not in roof support.
  → The bolts provides immediate strata supporting trough the friction between split tube and drillhole wall.
  → Once the maximum frictional resistance is overcome , the bolt starts to slide and keeps a constant supporting load at a rate of 0.75-1.0 ton per foot anchorage (depending on the diameter and strata).
  → Typical Lab pull test shown in Figures.
