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.

The solution to the corrosion of China 7*19-4.8mm wire rope
1. When China 7*19-4.8mm wire rope is corroded, the mechanical properties will be reduced, the diameter of the steel wire will be thinner, the inter-strands will be loose, and even brittle fracture will occur.
2. Whether in inspection or maintenance, when encountering steel wire rope corrosion, special attention should be paid, and careful observation should be made. If it is found that the corrosion is serious and has formed pits or the outer steel wire of the rope strands is loose, no matter how much the wire rope is broken or the diameter of the rope becomes thinner should be replaced.
3. If "red oil" is found on the China 7*19-4.8mm wire rope, it means that the rope core is oil-free and the inside is rusted. Attention should be paid to it. If necessary, the end of the rope can be cut to check the internal corrosion of the wire rope.

4. To prevent China 7*19-4.8mm wire rope from rusting, in addition to inspection and replacement, lubricating oil can also be applied to the steel wire rope for protection, so as to prevent rust.
5. The lubrication of China 7*19-4.8mm wire rope is to use a bristle brush to evenly and thinly apply a special lubricating grease on the surface of the steel wire against the running direction of the steel wire rope. The advantage of this method is that it is simple, does not need heating, and is easy to apply. The surface of the rope can be slightly penetrated and lubricated.
6. Or use a steel wire brush to remove the dirt and residues on the rope, wipe it with kerosene, and heat the lubricating oil to above 80°C to apply. China 7*19-4.8mm wire rope should be lubricated moderately, and the surface should not be oiled too much.
