The Rock Bolt Torsion Testing Machine is designed for static torsional testing of metal rock bolts, steel bolts, resin bolts, hollow bolts, and split-set rock bolts. The system measures torque and torsion angle while automatically generating torque-angle and torque-time curves for evaluating the torsional performance of rock bolt products.
The machine is suitable for testing:
(1) Metal and steel rock bolts
(2) Resin rock bolts
(3) Hollow rock bolts
(4) Split-set rock bolts
(5) FRP rock bolts
(6) Mining and underground support components
(1) MT 146.2 — Resin Anchor Bolt: Metal Bar and Accessories
(2) MT/T 1061-2008 — Resin Anchor Bolt: Glass Fiber Reinforced Plastic Bar and Accessories
(3) MT 218 — Cement Anchor Bolt: Bar Body
(4) MT/T 1061-2008 Appendix A — Loading System for Anchor Bolt Torque Testing
