The technological process of conventional lifting belt (synthetic fiber lifting belt) is divided into several steps. The fiber sling is mainly Lift webbing sling made of high-strength polyester industrial wire, and the weight is 25% of the equal metal sling. The characteristics of light weight, good flexibility and easy bending make it widely used in various fields. The technological process of lifting belt is as follows: yarn frame — textile — spot check — dyeing — cutting — sewing — spot check — thread cutting — packaging — spot check the finished product will be delivered to the factory after it is qualified. We need to pay attention to the industrial silk must be the same batch, batch of different raw materials elongation will be different. The finished product will also be greatly affected.Lift webbing sling
When weaving, the operation must be carried out in strict accordance with the standard width of the hoisting belt (the width changes before and after the weaving belt dyeing need to be paid attention to). When dyeing, we should pay attention to that only when the temperature and speed of the high temperature printing and dyeing machine reach a certain balance value, the dyed ribbon can achieve the best effect. There are no technical problems in the cutting, sewing, thread cutting and packaging of the lifting belt, only in strict accordance with the technical standards.Lift webbing sling
Lifting belt rigging is a kind of sling, which is mainly composed of synthetic fiber lifting belt and metal end fittings. When using, we need to pay attention to 1. When using the lasso, it is forbidden to use it over tonnage or overload. 2. During use, do not cross or twist the fiber sling, knot or twist it. 3. Pay attention to the Angle when lifting. The lifting Angle of the set of spreader should not exceed 60° when lifting. 4. During the use of the lasso (two, three, four legs), it is forbidden to use a single sling cable to force, and the load should be evenly distributed on each leg. When using sling lifting, it should be stopped in the following cases: 1. The sling body should be scrapped when it is cut, seriously scraped, loosely banded or partially broken. 2. Severe surface wear, abnormal deformation of synthetic fiber sling, wear reaches 1/10 of the original size width, should be scrapped. 3. Before use, check the fiber parts such as softening or aging (yellowing), rough surface, fiber peeling, elasticity becomes small, should be scrapped. 4. Lifting with mildew deterioration, acid and alkali burn, hot melting or scorching, loose surface, corrosion should be scrapped. 5. Lifting metal parts with rigging are seriously damaged and will be scrapped if deformation affects use.
