Conventional lifting belts (synthetic fiber lifting belts) are generally made of high-strength polyester filaments, which have multiple advantages such as high strength, wear resistance, oxidation resistance, UV resistance, etc. At the same time, they are soft, non-conductive, non corrosive (no harm to human body), and are widely used in various fields. There are many types of lifting belts. Conventional lifting belts (according to the appearance of the sling) can be divided into four categories: annular core piercing, annular flat, double eyes core piercing, and double eyes flat.
The sling is generally used in flammable and explosive environment, and does not produce sparks. Since the first synthetic fiber flat sling in the world was successfully applied in the field of industrial hoisting in the United States in 1955, it has been widely used in shipping, metallurgy, machinery, mining, petroleum, chemical industry, ports, power, electronics, transportation, military and other fields. The lifting belt has the advantages of portability, convenient maintenance and good chemical resistance, as well as the advantages of light weight, high strength and not easy to damage the surface of the lifting object. It is more and more popular among users and gradually replaces the wire rope sling in many aspects.
The disadvantages of lifting belts are mainly different from wire rope slings, which are mainly shown as follows: when the lifting objects have sharp edges, these sharp edges will cause destructive cuts to the lifting belts. To protect the lifting belts from cuts, a protective lining can be placed between the lifting belts and the objects to be lifted.
Light and soft: the weight is 25% of the same metal sling. The sling is very easy to handle, carry and store. If there is a large cut on the circular sling casing, it must be inspected and cannot be repaired or used again.
Analysis on the Characteristics and Uses of Lifting Belts
Lifting belts are increasingly used in modern, scientific and international lifting construction sites. The products are widely used in steel mills, oil fields, ports, electromechanical, transportation and other industries.
(1) Light weight, good flexibility, easy to bend, easy to use
(2) It does not damage the appearance of the hoisted object and has strong maintainability;
(3) Safe and stable lifting, high safety coefficient;
(4) High tensile strength, beautiful color, easy to distinguish;
(5) It is an insulator;
(6) Long service life, good corrosion resistance and wear resistance;
(7) Progress, rest, obedience and cost saving;
(8) It is widely used in aviation, aerospace, nuclear power construction, military manufacturing, port loading and unloading, electric power devices, machine processing, chemical steel, shipbuilding, transportation and other fields.
Performance:
Strength: flat sling 1T-30T round sling 1T-300T
Bandwidth: 25mm-250mm
Elastic elongation:<10% under rated load 2% - 3% under ultimate working force
Load identification: in the process of use, the bearing tonnage can be identified by the color of the sling jacket after the tag on the sling is worn.
Working temperature: - 40~100 ℃ Safety factor: 5:1 6:1 7:1
advantage:
1. Light weight, easy to use;
2. Do not damage the surface of the object to be lifted;
3. The lifting is stable and safe;
4. High strength, tonnage can be judged according to color;
5. Improve labor efficiency and save costs;
6. Good corrosion resistance and wear resistance;
7. It is widely used in ports, docks, chemicals, steel, machinery, installation and other lifting places.
