Under normal circumstances, for small tonnage lifting belts under 100 tons, in the case of normal lifting operations, it can be repeated more than 500 times. For large lifting belts of 100-500 tons under normal lifting conditions, 300 can be repeatedly lifted. Around time, for a large lifting belt with a capacity of 500 tons or more, it can be repeated about 200 times.
However, it does not mean that the above number will be scrapped. The above is only a reference value. If the lifting belt is damaged or scratched due to different environments, it cannot be reused. The technician should make a detailed inspection to determine whether it can be repaired and continued to use.
The lifting straps of the slings are made of synthetic fibers with high strength and good toughness. They are lighter than steel ropes, chains, etc. They are easy to carry, easy to maintain and have a wide range of applications.
The work is often inspected to avoid sharp edges cut slings, reduce UV radiation, prevent fade, harden, reduce strength and other conditions. Avoid damage caused by acids, alkalis, and other chemical substances. Do not work in a place where high temperature and sparks are easily generated. This is because the material of synthetic fibers has poor resistance to high temperatures.
Slings are generally used in flammable and explosive environments and do not produce Mars themselves. The world's first synthetic fiber flat lifting belt has been widely used in ships, metallurgy, machinery, mining, petroleum, chemicals, ports, power, electronics, transportation, military, etc. since it was successfully applied to industrial lifting in the United States in 1955. field. The lifting belt is portable, easy to maintain and has good chemical resistance, and has excellent characteristics such as light weight, high strength, and less damage to the surface of the lifting object. It is increasingly favored by users and gradually replaces the steel wire rope in many aspects. With.
