There is a rule that more sutures are not better for colored polyester lifting straps. The suture of conventional color lifting belt is divided into single layer, double layer, three layers or four layers, so in order to improve the wear resistance, can we sew more layers? The answer is no.
According to the Lifting Sling safety load breaking record given by the Lifting Sling Belt manufacturer, it is found that the synthetic fibre semi-product Belt is the dominant force of tension, while the Lifting Sling Belt supplier finds that it is the suture of the Lifting Sling Belt that affects the breaking force the most. The more sutures there are, the less force it will eventually break. Normally safe breaks are always the most sewn sections. Because every stitch of the sewing machine is the loss of the lifting belt tension. According to years of production experience and specific data, the stitches of Lifting Belt stitched by conventional color Lifting Sling Belt should be no more than 10-15 stitches within 10cm. The stitches of supplier of Lifting Sling Belt should be horizontal and vertical.
The white lifting belt is made of polypropylene, which is pickling resistant and UV resistant, also known as pickling lifting belt.Lifting Sling Belt supplier
Lifting Sling Belt can be divided into single layer, double layer and four layers, and the supplier size of the Lifting Sling Belt can be customized according to the customer’s requirement (1-10 tons load, 1-100 meters in length). The Lifting Sling Belt has a wide surface, which can reduce the pressure of the surface load. When pickling sling is used to lift objects with smooth external surface, it will not hurt the objects to be lifted. Anti-wear protective sleeve and anti-cut protective sleeve can be attached, and the safety factor ratio is 4:1 3:1 5:1.Lifting Sling Belt supplier
Lifting belt material is different, performance is not the same, the use of the environment is not the same, so the lifting belt from the material is divided into: polyester (PES polyester), polypropylene (PP), nylon (PA: polyamide. Nylon), Dinima (Dupont), etc. At present, the common ones in the market are polyester and Polypropylene fiber. The colorful flat lifting belt and circular lifting belt (polypropylene fiber) that we see in our daily life are both of polyester.
Different processing technology will be made into different types of hoisting belt, such as: flat ring, double lifting belt is made from loom to industrial filament one-time compiling, and circular lifting belt is formed with infinite around using industrial wire loop shape bearing core, external again with industrial woven not stress of casing was carried out on the bearing core protection. The completely different production process makes the hoisting belt more widely used.
Although polyester can resist most inorganic acids but not alkali resistance, but polypropylene hoisting belt can just meet this point, polypropylene almost immune to acid and alkali erosion. Because of poor dyeing, incomplete chromatography and later color cannot pass through the high temperature dyeing machine, the white hoisting belt we can generally see is made of polypropylene fiber. Nylon is the first synthetic fiber material developed by DuPont, but because the price of nylon industrial filament is about twice higher than that of polyester industrial filament, the price is low, so the lifting belt of this material is not common in the market.
The last kind of special lifting belt is the Dinema lifting belt because we hear about it all the time. Denima (Dupont wire) it is made of the same kind of industrial wire called high molecular weight polyethylene, both just because different companies manufacture, so the name is different. The LIFTING BELT made OF this industrial silk IS one fourth of the weight of the ordinary lifting belt, and the diameter is one half of the ordinary lifting belt. Although the raw material performance is good, its price is more than 10 times that of the ordinary raw material.
