Anchors & Related Strata Control Products

Fabchem manufactures mechanical, spin, multi- strand, de-bonded and double corrosion protected type anchors, which are manufactured to the client’s required specifications (anchors can be made to suit any hole size). All safety critical ranges are tested at the CSIR, to ensure compliance to the required safety standards. Fabchem produces a variety of lock- off barrels, to suit various applications. The PLV Series of barrels is Fabchem’s newest innovation in barrel technology, which features anti-preactivation, specified load tension indi- cation and over-load tension indication. 

Spin Anchor

Spin Anchors are primarily used as secondary support in soft rock mines, especially coal mines. The anchor are usually point anchored with quick set resin and, dependent on the Rock Engineer’s requirements they may also be grouted.

Spin anchors are manufactured to the customer’s
requirements and are supplied complete with dome plate, barrel & wedge. In the event that the anchor is to be grouted a grout tube, breather tube & gasket will be provided separately
Fabchem also manufactures multi-bulb passive anchors with fishhooks. The bulb spacing is carried out to the client’s specification.

 

Spin Trusses

Spin Trusses are generally used for supporting slips, faults, bullnoses, large roof spans, friable roof conditions (used in conjunction with mesh and straps), pillar wrapping (support).Trusses are made to the client’s required length.

Mechanical Anchors

Mechanical Anchors are primarily used as secondary support in hard rock mines. They are used both in development ends and in the stopes. Mechanical Anchors are usually full column grouted and anchors are supplied complete with dome plate, barrel, wedge and grout fittings (breather tube, grout tube and Gaske ).

Dynamic & Destructive Testing Of Anchors

Dynamic testing of anchors being carried out on our 50 tonne test rig. Pre-load indicators are tested to ensure that they activate at the specified loads. Shock testing is carried out on the anchor to simulate a blast in situ. Anchor barrels are struck 3-4 times with a 4– pound hammer to check that the anchors do not lose excessive load. Anchors are also tested to destruction to validate ultimate breaking strength. CABLE ANCHORS (PATENTED PLV SYSTEM) Mechanical, Spin & Passive Multiport, Multi-Strand Civil Anchors Trusses (Spin & Mechanical)STRESSING & GROUTING EQUIPMENTWire Mesh & Welded Mesh GroutThixotropic, pumpable anchor groutRock Magic+ Rock Magic LAGProduct Application / Installation Training Thin Sprayed Liner (TSL)TSL Poly & TSL-WOsro Straps Hydraulic Stressing Pumps (Manual & Air Intensified), Tensioning Jacks, Strand Croppers, Pull Testers, Hand Grout Pump / Mixer Combos, Air Grout Pumps /Mixer Combos, Equipment Training.
