What are the main classifications of lifting belts
1. Flat lifting belt
Industrial strong yarns are woven into dyed industrial webbing, widths of 15mm, 30mm, 50mm, 60mm, 75mm, 90mm, 100mm, 120mm, 150mm, 180mm, 240mm, 300mm, hanging The ear widths are 30mm, 50mm, 60mm, 70mm, 80mm, 100mm. Industrial webbing is industrially sewn into a flat lifting belt. There is a hoisting ring on each side of the flat eye hoisting belt, and an anti-wear sheath is sewn on the hoisting ring. Several layers of webbing are stitched together in the middle part of the flat eye sling. The flat ring sling is just a ring.
2. Round sling
A closed load-bearing core is composed of filament bundles that are arranged in an endless circle and equally arranged. Single-strand filaments are used for twisting. The number of filaments in a row is more than 100,000 cycles, which plays a bearing role. The round slings are round and have no eye shape.
The outer layer of the circular hoisting belt is a special double-layer wear-resistant sleeve butt-connected into a ring shape. The outer sleeve is not load-bearing and only protects the parallel tows. When severe overloading or long-term use causes partial damage to the load-bearing core, the jacket will first break and warn to avoid accidents. If there is a big cut on the round hoisting belt sleeve, it must be checked to see if it can be repaired or continue to be used. In any case, if the user is not sure of the degree of damage, it is best to send the round sling back to the manufacturer for further inspection.
3. Synthetic fiber sling
It is a soft sling with excellent performance. It is made of high-quality high-strength and low-elongation polyester filament. It is a replacement product of steel wire. It has been widely used in developed countries in the world for more than 50 years. Its superior performance is well received by users. Its main characteristics are: light and soft: the weight is 25% of the same metal sling, the sling is very easy to operate, transport and store. Does not damage the surface of the hanging parts (including the paint layer), and does not cause any negative harm to the human body. Safe and reliable: in the process of use, it has the characteristics of shock absorption, corrosion resistance, aging resistance, non-conductivity, and no sparks in flammable and explosive environments. The elongation under the rated load is 1.6%, and the tensile properties are close to that of a steel wire rope. The use status of the sling is clear at a glance, and the daily safety inspection is intuitive and simple. It can be considered that the sling that looks intact is intact. The synthetic fiber sling is soft and easy to handle. Anti-corrosion and non-conductive.
