Chen summarizes what impact force by using the sling can cause life reduced by 1, lifting objects sharp edges: When lifting objects with sharp edges, these sharp edges will flat sling devastating cuts, To protect the sling against cuts, between sling and hanging objects available with a protective liner placed. 2 UV: exposure to UV light in a continuous breaking strength sling, suggested the following ways to try to avoid being influenced by ultraviolet light or arc of light. When not in Shandong lifting belt, lifting belt will be stored in ventilated, cool, dry place. According to harness the use of the sling checked once a week or more. UV damage degree visual method: lifting belt color fading, sling material sclerosis; in the sling load of parts appear infrequently in contact surface wear. Test & Manufacturer of flexible lifting belt, lifting belt for continuous testing by ultraviolet irradiation test. 3, the acid will affect the characteristics of nylon, or even completely destroy the strength nylon; many acid does not affect the characteristics of polyester, but some acid polyester will generate low to moderate damage. 4 base does not affect the characteristics of nylon, but some nylon base will generate low to moderate damage Guangdong sling, polyester base will affect the characteristics of, or even completely destroy the strength of polyester. There are occasions when the use of acid loading zone, to deal with the following factors to be evaluated: types of acids, bases or other chemicals; the degree of acid exposure; concentrations; temperature. Lifting with a wide range of different lifting with different characteristics, sling soft and not hurt the items to protect your hands. The use of light, a greater load, long service life. Lifting the work force with clear limits and color-coded labels, improve the safety performance of lifting belt does not hurt the surface of the object to be hung, colorful high-strength, corrosion resistance, good abrasion resistance performance lifting smooth and safe. Lifting with diverse species, different in different places to hang items can use different kinds of sling. SLING into flat sling, round sling, they also have their own sub-categories. Such as: round sling internal bearing core using Promise surround a circular shape, the external use of 100% PES woven into the casing to protect against power lifting belt for carrying yi, and the most common occurrence in the lifting action of the constitution is dangerous Damage caused by impact, and round sling under the strong impact only flat, so the risk is zero; flat sling is made using 100% PES suture through the preparation and processing methods with different stitching together , divided into single and double. When lifting operations, providing a wide, smooth bearing surface, especially for soft surface when lifting objects, because there is no contact with the metal parts, for hanging objects by surface spray treatment of damage caused by extremely slight. Flat sling, sling manufacturers (online consultation), lifting belt sling from Hebei chen Manufacturing Limited. Hebei chen sling Manufacturing Co., Ltd. (www.qzhon.com) Hebei Baoding, forestry machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Chen led force in a sling with the staff warmly welcome all inquiries negotiations to create chen sling a better future.
