1. Introduction
→Used in tests of pre-tightening force, tightening axial force, yield tightening force, yield clamping force, limit clamping force, proof load, break load, torque, torque coefficient, torsion angle for bolts, nuts, screws, studs and other fasteners and its connection pair, with class12.9, 10.9, 9.8, 8.8, for pre-tightening force, fastening force, yield fastening force, yield clamping force, limit clamping force.
→Used on torque coefficient test for various standard fasteners, stainless fasteners, special fasteners, friction high strength bolt connection pair, tensile high strength bolt connection pair, torshear high strength bolt connection pair, large hexagonal high strength bolt connection sets, double head bolt connection, square-head bolt connection, etc.
→Used in large torque test for high strength large diameter bolt.
→Used in torsion property test for bolt with length of 3d-500mm.
→Used in torque coefficient test for ocean platform, marine heavy equipment, heavy-duty truck trailer, highway bridge, railway transportation equipment, mine equipment, hoisting equipment, engineering machinery, transmission equipment, wind and nuclear power station, industrial and civil construction, steel structure building, etc.
→The machine combine large torque of main system and small torque of vice system can be customized to realize large torque test for high strength bolt with large diameter and small torque test for common bolt with small diameter.
→Camera system can be customized to record test process of bolt torsion in the real time and realize synchronous communication between graphs acquisition system and software operation system.
→The precise torsion angle meter with resolution 0.0001°can be customized.
