The main damage phenomena of wholesale 6*7+1*19-4.8mm wire ropes are as follows: wear, fatigue, corrosion, deformation, rope biting, and overload.
In the production process of cheap 6*7+1*19-4.8mm wire rope, the quality of twisting is the key, if the control is not good, it is easy to have quality objections.
There are generally the following methods for lubricating or refueling China 6*7+1*19-4.8mm wire ropes: Brushing - manual method, low efficiency. Dumping - manual method, low efficiency and wasteful. Oil Bath - Dip in heated oil for good penetration.
1. Check before use Scope of inspection: check the degree of wear, corrosion, stretching, bending, deformation, fatigue, broken wire, and rope core exposure of the galfan wire rope, and determine its safe lifting capacity (including scrapping).
1. Since the customized 6*7+1*19-4.8mm wire rope is composed of multiple steel wires, in the working state, the relative slip of the steel wires caused by the bending of the steel wire rope will produce a large friction force. The special grease for the steel wire rope can ensure the friction between the steel wire rope and the traction force Under the premise of reducing the friction between the wires, effectively prolonging the service life of the wire rope.
6*7+1*19-4.8mm wire rope has the characteristics of the same section, high strength, high elasticity, good toughness, wear resistance, stable high-speed operation and can withstand impact loads. Widely used in lifting operations, it is the main rope in hoisting, and can be used for lifting, traction, binding, etc.

Information

Many people have encountered all kinds of troubles in the operation of customized galvanized steel wire rope. The following briefly describes some problems and solutions.
1. Wear: It is a common phenomenon. Choosing the correct construction of galvanized wire rope ensures that wear is only a secondary factor in damage, and lubrication to help reduce wear.
2. Broken wire: It is a common phenomenon at the end of the service life of customized galvanized steel wire rope, which is caused by bending fatigue and wear. Locally broken wires may indicate mechanical defects in the equipment, and proper lubrication will improve the fatigue performance of the wire rope.
3. Deformation: It is often the result of mechanical damage. If serious, it will greatly affect the length of the customized galvanized steel wire rope. Rusting indicates lack of proper lubrication causing rust. In some cases, visible rust marks appear on the outer surface of the wire, which eventually leads to wire breakage.

4. Internal rust: occurs when the lubrication is insufficient or the method is incorrect.
5. Multi-layer winding: Multi-layer winding on the reel will cause serious deformation of the lower wire rope.
6. Poor winding: It is mostly caused by too large inclination angle or too loose winding, which will cause mechanical damage, which is manifested as severe extrusion, and may cause sudden load during operation.
7. The diameter of the sheave is too small: it will cause permanent deformation of the customized galvanized steel wire rope, and will inevitably cause premature wire breakage.
8. The rope groove is too large: the sheave rope groove exceeds the nominal diameter by more than 15%, which will cause the wire rope to lack sufficient support, resulting in flattening and premature wire breakage.
9. The rope groove is too small: the customized galvanized steel wire rope will be squeezed and deformed, and two obvious wear marks and corresponding broken wires often appear.
