The difference between galvanized steel wire rope and ordinary oil rope

Correctly selecting the right crane wire rope material is the key to ensuring the safe operation of the crane and extending the service life of the wire rope. The following are some factors and steps to consider when selecting the material of the crane wire rope:

1. Understand the basic material of the wire rope

The material of the crane wire rope mainly includes two parts: steel wire and rope core. Steel wire is the main body of the wire rope, and its material and performance directly affect the load-bearing capacity and service life of the wire rope. The rope core plays a supporting and lubricating role. Common rope core materials include steel core, hemp core, etc.

2. Consider the use environment and conditions

Working environment:

If the working environment is humid and corrosive, a wire rope with good corrosion resistance should be selected, such as stainless steel wire rope.

When working in a high temperature environment, a high temperature resistant wire rope should be selected, such as an asbestos core wire rope.

Load conditions:

Crane carrying heavy objects should choose a wire rope with high breaking force and wear resistance, such as a steel core wire rope.

For occasions that require frequent bending, a wire rope with good fatigue resistance should be selected.

Service life: Considering the service life of the wire rope, you can choose a specially treated wire rope, such as a phosphating coated wire rope, which has a significantly higher fatigue life than a smooth wire rope.

3. Consider economy and maintainability

Economy: The price of the wire rope varies depending on the material, process and specifications. You should choose a product with high cost performance while ensuring performance.

Maintainability: A wire rope that is easy to inspect and replace can reduce maintenance costs and improve work efficiency.

4. Specific material selection suggestions

Steel core wire rope: Suitable for cranes that carry heavy objects, with large breaking force and good wear resistance.

Hemp core wire rope (including sisal rope core and jute rope core): It has good lubricity and flexibility, and is suitable for occasions that require frequent bending, but its load-bearing capacity is relatively weak.

Stainless steel wire rope: It has good corrosion resistance and is suitable for highly corrosive environments such as marine engineering and coal mines.

Phosphating coated wire rope: The surface wear resistance and corrosion resistance of the wire rope after phosphating treatment are significantly improved, and the fatigue life is long, which is suitable for various harsh environments.

Cold-headed, hot-headed and prestressed wire ropes: These wire ropes have the advantages of high strength, good fatigue resistance and long life, and are suitable for use under harsh conditions such as high strength and repeated bending. However, it should be noted that their production and testing are difficult and the cost is relatively high.
