First of all, what is the lifting belt? Lifting belt is easy to understand from the literal meaning is lifting loading and unloading of lifting equipment, generally USES industrial wire, wear resistance, high strength, oxidation resistance, resistance to ultraviolet light, material is qualitative soft, non-conductive, no static, many features such as light weight relative metal rigging is widely used in various fields, such as port, container flow station, power plants, chemical plants, ports, shipyards, and so on. The following is a detailed description of the hoisting belt type, process, material and other aspects according to the hoisting belt implementation standards.
I. Implementation standard of lifting belt Webbing Sling Belt manufacturer
At first, there was no execution standard for hoisting belt. Considering the rapid development of Chinese hoisting belt industry, we needed to formulate the standard for hoisting belt in 1997. According to the characteristics of Chinese sling industry and according to the European standard EN1492-1, the hoisting belt execution standard document was mainly drafted by Beijing Hoisting Yuanshu Machinery Research Institute, Academy of Mechanical Sciences and the core backbone of several rigging groups Yang Jianguo, Cui Zhenyuan, Yao Junzhan, Liu Yonghui and Li Yanying. Domestic flat lifting belt implementation standard: JB/T 8521.1-2007 round lifting belt implementation standard: JB/T 8521.2-2007
Second, lifting with common sense
1. Hoisting belt type and material
The hoisting belt can be divided into four types: annular core piercing, annular flat, Webbing Sling Belt manufacturer binocular core piercing, and circular eye flat. From the raw material is divided into polyester (PES polyester), polypropylene (PP polypropylene), cotton fiber (PA polyamide), Dyneema (Dyneema polyethylene) these 4 common materials. In terms of production technology, it can be divided into flat lifting belt and flexible lifting belt.
2. Color discrimination tonnage
The tonnage of lifting belt can be identified according to the color, 1 ton (purple) 2 tons (green) 3 tons (yellow) 4 tons (gray) 5 tons (red) 6 tons (brown) 8 tons (blue) 10 tons (orange)
3. The components
The lifting belt is mainly composed of closed surface, round eye (soft round eye) and end fittings (main chain ring).Webbing Sling Belt manufacturer
4. Common terminology
Flat lifting belt, multi-layer lifting belt, suture, annular eye, main chain ring, nominal length, effective working length, ultimate working load, mode coefficient, failure, inspectors, breaking force, bearing core.
