Hanging rigging safety management has not yet incorporated into the normal channels, extensive management at present, for hanging the safety management of the rigging, the country has not developed a unified and standardized management standards, enterprises lack corresponding safety management system, resulting in hanging rigging of the safety management in a loose state. For the use of units (enterprises) sling put into use after, what is managed by the Department, the long test time, by whom to check to what standard should repair or scrapped, these are impossible to implement. Resulting can not discover and eliminate sling the existence of hidden dangers, so that part of the sling long-term "in spite of operation", until the cause of the accident. Moreover, the production workshop or process is concerned, there is no fixed person management, fixed-point storage. Who take, after littering, which makes the sling fracture greatly increases the chance.
Manufacturing rigging is not standardized. At present, enterprises use sling into professional factory production enterprises and made two parts. Sling a professional manufacturer of product quality is an important cause of the accident. Some of the rigging manufacturers and test products according to the requirements of national standard. For example, a factory in 1999 purchased 8 tons of 10 tons of ring welding chain, which has a sudden break in the use of. After inspection, chain weld department fracture obvious open welding, are neither certificate and test marking and quality grade mark "three noes" products. Some enterprises in the purchase rigging at the same time, also make full use of existing enterprise equipment and human resources, processing their own making some process is simple and the number of single sling. The enterprise homemade sling, random and blindness of larger, in the material, when determining the size and the production method, often by experience and, manufacturing quality and safety performance is difficult to meet the requirements of use. Such as: our factory workshop in 2000 forged a pair of 2 tons of small hook, because the standard DG series steel (using steel ordinary 45# manufacturing, in use hook is straightened, hanging things fall, nearly causing casualties.
Sling with the safety of the personnel and technical quality is low, poor safety awareness sling using personnel security technology quality and safety consciousness is not strong, not only affects the working quality, but it is directly related to the user's personal safety. Its performance mainly has the following several points, one is the use of personnel security awareness. In the production process, some sling heavy production, light security personnel, to grab progress, rush period, simplify the operation process, even illegal adventure homework and stuffed accident. Second, lower some personnel's quality of security technology. They don't know basic properties of rigging and use requirements, but do not know how to calculate hanging focus and determination method of hanging, that in the specific operation, arbitrary, can not guarantee lifting safety, completely rely on the hit "Universiade".
