Product Introduction

Double-layer slings are manufactured through a double-layer weaving process. This product combines the portability of single-layer slings with the enhanced bearing capacity of the double-layer structure, forming unique mechanical performance advantages. The inner layer provides basic bearing capacity, and the outer layer enhances wear resistance and cut resistance. The overall tensile strength is more than 50% higher than that of the single-layer.

Product Advantages and Features

1. Coexistence of High Strength and Lightweight

Structural Enhancement: The double-layer weaving process controls the elastic elongation of the belt body within 3% during vertical lifting, and the elongation under breaking load does not exceed 10%, ensuring lifting stability.

2. Multi-scene Adaptability

High-temperature resistant models can be used in the range of -40℃ to 300℃, suitable for lifting power equipment and furnaces.

The anti-corrosion coating can resist the erosion of acid, alkali, salt solutions and various organic solvents, extending the service life to 3 times that of traditional products.

3. Safety Early Warning and Easy Operation

The outer cover is designed with a wear-resistant sleeve. When the load-bearing core is partially damaged due to overloading or long-term use, the outer cover breaks first to warn, avoiding accidents. In port cargo lifting, double-layer slings can quickly adapt to the binding needs of goods of different shapes, improving work efficiency by 40%.

4.Economy and Maintenance Cost

The maintenance cost of double-layer slings is only 1/5 of that of steel wire ropes. The state of the belt body can be judged by visually inspecting the wear of the outer cover, and the maintenance time is 80% shorter than that of traditional spreaders.

Industry Applications

1. Heavy Industry Field

Steel Smelting: In the Baowu Aluminum Industry project, double-layer slings successfully lifted 400-ton rolling mill archways.

Mechanical Manufacturing: Used for lifting precision equipment such as engines and gearboxes, avoiding damage to coatings by metal spreaders.

2. Energy and Petrochemical Industry

Oil Pipeline Installation: The oil resistance of double-layer slings ensures long-term stable use in crude oil environments.

Wind Power Equipment Lifting: Double-layer slings shorten the installation cycle of wind turbine towers, reducing the lifting time of a single unit by 6 hours.

3. Port and Ship Field

Container Loading and Unloading: Double-layer slings fix irregular goods through flexible surrounding methods, reducing the risk of goods slipping.

Ship Maintenance: Seawater corrosion-resistant models are used for hull section lifting.

4. Aerospace and Emergency Rescue

Aircraft Mooring: The anti-ultraviolet performance of double-layer slings ensures long-term outdoor use.

Disaster Rescue: Double-layer slings quickly set up temporary lifting systems, and their quick connection characteristics shorten the rescue response time.

5. Special Engineering Field

Bridge Construction: In the Hong Kong-Zhuhai-Macau Bridge project, double-layer slings were used for the precise positioning of steel box girders, and their low elastic modulus characteristics reduced vibration during lifting.

Nuclear Power Equipment Installation: Radiation-resistant coating models meet the special requirements of nuclear power plants for spreaders and have been applied to multiple third-generation nuclear power projects.
