Rock Bolt Torsion Testing Machine
Category：Torsion Testing Machine
Introduction
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.
Application
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
Standards
(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
