The detection basis for the residual breaking strength of wire ropes after misalignment includes GB/T 8358-2014 "Method for Determination of Actual Breaking Force of Wire Ropes" and TB/T 3089-2004.
GB/T 8358-2014 "Method for Determination of Actual Breaking Force of Wire Ropes" provides the method for determining the actual breaking force of wire ropes, which is crucial for evaluating the residual breaking strength of wire ropes after misalignment.
TB/T 3089-2004 clearly specifies the requirements for the anti-misalignment tensile strength and anti-disengagement tensile strength at the crossover points of wire ropes, wherein the residual breaking strength of wire ropes after misalignment should not be less than 90% of the original minimum breaking strength.
These standards ensure that wire ropes maintain a certain level of strength and safety after experiencing misalignment, thereby safeguarding the safety of wire rope applications. Additionally, proper testing methods and standards are significant for preventing accidents and improving safety performance.

Main functions of the residual breaking strength testing machine for wire ropes after misalignment:
This machine can perform mechanical property testing and analysis on various metals, non-metals, and composite materials, widely used in industries such as aerospace, petrochemicals, mechanical manufacturing, plastics and rubber, ceramic building materials, metal materials, and construction engineering.
It can conduct tensile, compression, bending, peeling, shear, tearing, puncture, burst, and various high and low-temperature tests according to standards such as GB, ASTM, JIS, and DIN. It can detect parameters such as yield strength, tensile (bending, compression) strength, elongation, non-proportional strength, and elastic modulus of specimens.
Relevant standards for wire rope breaking strength testing machines and wire rope tensile strength testing machines:
GB/T 228.1-2010 "Metallic Materials—Tensile Testing—Part 1: Method of Test at Room Temperature"
GB/T 8358-2006 "Method for Tensile Testing of Wire Rope Breaking"
GB/T 5754.2-2005 "Determination of Tensile Strength of Wire Ropes and Conveyor Belts"
Maintenance of the residual breaking strength testing machine for wire ropes after misalignment:
All parts of the tensile testing machine should be frequently wiped clean. For un-painted parts, after wiping, use a cotton cloth dipped in a small amount of machine oil to wipe again to prevent rust. Pay extra attention to wiping during the rainy season. When not in use, cover with a dustproof cover to prevent dust intrusion. After each test, lower the test platform without letting the piston reach the bottom of the oil cylinder, leaving a small distance to facilitate the next use. All valves on the dynamometer should not be left open to prevent dust from entering and affecting the sensitivity of the measurement mechanism. When pausing the test, turn off the oil pump.
