Knowledge of the basic knowledge of wire rope

Appearance size inspection: the wire rope diameter (including roundness) surface, structure, twist and twist quality and other items of inspection.

Wire rope stranding test: wire rope part or all of the broken or monofilament test to calculate the wire rope within the sum of the tensile strength and assessment of the performance of steel wire rope.

Wire Rope Breaking Tensile Test: The test of the tensile strength of the wire rope under uniaxial tension.

Relaxation test: wire rope in the initial tension, after a certain period of time, the determination of its stress loss test.

Flattening test: the test of the degree of deformation of the wire rope under the action of pressure.

Fatigue test: the determination of the provisions of the wire rope under the alternating pressure, to withstand the repeated bending capacity of the test.
