– Friction bolts can be subjected to the full load directly after they have been positioned and are immediately able to absorb rock movements – Bearing force is applied along the complete length of the inserted bolt. EEXBOLT friction bolts supplied in steel grade S355 MC.
A friction bolt assembly has a tubular friction bolt body defining a cavity and having a split. A rod extends through the cavity. An expansion element is mounted on the rod at or toward the rod leading end and protrudes through the friction bolt body leading end. The expansion element has an engagement surface tapering toward the rod trailing end.
Nuts and bolts compress the rod and transfer forces into the rock composition, stabilizing it. Friction Rockbolts: Friction bolts work by being driven into predrilled holes that are slightly smaller in diameter than the metal rod or dowel. This creates a strong friction force .
The 47mm Mechanically Point Anchored Bolt in addition to standard frictional forceprovides a tensionable point anchor by way of an internal solid bolt. The KINLOC Bolt uses standard installation procedures with the addition of tensioning the base nut, via rotation of the installation socket spanner in a single pass.
underground mining rock anchor bolt 46mm split set rock bolt Friction bolt (Split sets) is roll formed into a C shape bolt with slot by high tensile steel band,which o ne end is tapered for eas ily insert ing bolt into drill ing hole. Functions Friction bolt (Split sets) is a frictional ground support system.
Friction Bolt is temporary rock reinforcement in Mining and Tunneling. Bonding forces between the friction bolt and the rock mass are caused by form closure and friction transfer between the borehole wall and the rock bolt which is expanded by hydraulic pressure.

Several factors can affect the torquetension relationship. These include friction in the threads (affected by thread tolerances, rust, dirt, etc.), friction between the wedge and leaves in the expansion shell (affected by dirt, casting roughness, etc.) and friction between the bolt head (nut) and plate washer (influenced by angularity, rust, rough edges on nuts/plates).
Cable bolt. Cable bolt is made of grade 1860Mpa steel wires,which can be made into plain cable bolt and bulbed cable bolt. Functions.
