3) Tunnel building, mining industry, slope management, protective for palisades , wall of mine, roadway.

4) Diameter of anchor bolt: D16mm, D18mm, D20mm, D22mm, D24mm.

5) Length of anchor bolt: L=1400mm, 1600mm, 1800mm, 2000mm, 2200mm, 2400mm, 1600mm.

2 Torque Test of Anchor Bolt

1) Put anchor bolt into torque gripper, supportor of bolt is placed in the middle, speed of torsion test machine is between 200r/min and 300r/min, stable loading to specific torque in 8s, cycle rotaing for 40s, there should be no breaking, seriou deformation and other unusual condition.

3 Important Characteristics

1) Horizontal type loading frame with high rigidity and stability.

2) Control mode: loading kept, control of stress and strain, fatigue cycling control, self editing and so on.

3) High precision tranducer with wide linerity an well stability.

4) Muted alternating current servo motor system with high speed low vibration and without maintenance.

5) Inner ethernet web joint.

6) Circuit board adopts photoelectricity designing without interference.

7) With variety of torsion gripper, speed and environmental system is changable.

8) Wide test speed: 0.05 -- 500r/min, 0° -- 720°/min choose freely.

9) Fully digital close loop HRJ -- test soft ware with multiple channel, function and operating easily.

9.1 test procedure is auto contolled, torque, stressed, strain, angle of torque is fully close loop controlled and displayed, fully key board inputting operation and control mode setting system, control mode is set freely without vibration, shifting smoothly, loading and unloading steadily.

9.2 flexible Excel and Word reporting format with basic and self editing format, arrangement and outputting of variety of type.

9.3 reread completed test, simulating reappear and reanalyze data, curves is overlaid and compared with ergodicity.

9.4 test curve choose coordinated axis freely, curves are magnified and shrinked freely, several curves are displayed at the same time, such as curves of torque and time, torque and angle, angle and time and so on, full scale is self adjusted.

9.5 modulization and openning type of programming satisfying individual demands with hinting and guiding.

9.6 auto return after test completed with high efficient and speed.

9.7 torque and angle of torque is auto traced, curves, torque, angle of torque, speed of torsion is able to be displayed.

9.8 multiple protective: over loading, current, voltage and safety protective, stopping protective of urgency.
