How long does the wire rope test take? Regular non-destructive testing of wire ropes

How long does the wire rope test take? Regular non-destructive testing of wire ropes
Which wire ropes need regular non-destructive testing? Long-term use of wire ropes will rust, break, and wear, reducing the strength of wire ropes; if not replaced in time, short rope accidents will occur.
The inspection of wire rope is divided into independent inspection and regular inspection. Independent Inspection: Workers conduct an independent inspection of the wire rope used every day before and after using the wire rope to lift the goods. Regular inspection means that the company finds a third-party inspection unit to conduct regular comprehensive inspections and issue inspection reports. For example: elevator wire rope, crane wire rope, rigging wire rope, mine elevator, mining wire rope, etc.
How long is the wire rope inspection?
The inspection period of wire rope is generally one year, six months or three months. Regularly conduct non-destructive testing on the wire rope, and then record the abnormal situation of the wire rope in time. According to the test results of the wire rope, guidance is provided for the later oiling maintenance of the wire rope. At the same time, if you want to estimate the service life of the steel wire rope, you need to test it once a month, test multiple times and combine multiple data, and then comprehensively judge the service life of the steel wire rope.
The following problems of wire rope need attention, and should be tested and evaluated as soon as possible:
1. The wire rope is broken by more than 10% in one twist;
2. The diameter is reduced by more than 7% of the production regulations;
3. Twist the wire rope;
4. The wire rope is obviously deformed or corroded.
Methods of nondestructive testing of wire ropes.
There are many non-destructive testing methods for wire ropes, including ultrasonic testing methods commonly used in non-destructive testing, radiographic testing methods, eddy current methods, current methods, vibration methods, and acoustic testing methods. At present, the main popular detection method on the market is electromagnetic detection, which is often referred to as the detection method of the principle of strong magnetic flux leakage, which can accurately judge the broken wire wear of the wire rope.
The manufacture of steel wire ropes is made by combining multiple steel wires into strands, which are twisted into ropes to obtain higher strength. Wire ropes are used in a wide range of applications, from anti-fall devices to some components of spring hoisting hoisting equipment, to elevator hoisting traction ropes and slings required for hoisting on construction sites. To sum up, no matter what kind of environment the wire rope is used in, we need to check the current situation of the wire rope at the first time. Of course, the most important thing is whether the wire rope breaks. The breakage of any steel wire will greatly reduce the safety factor of the entire steel wire rope, thus facing a great safety hazard, so this link is very important.
