"Predetermined conditions" refers chain conditions of product use and maintenance conditions, environmental conditions and test norms g80 lifting chains, chain product reliability has a direct impact on these conditions, under different conditions, the same product Reliability is not the same. So lifting chain, "predetermined condition" is a prerequisite for a measure of product reliability. "Predetermined function" is often used various performance indicators to indicate the product chain. Chain products meet specified performance indicators (such as life, minimum tensile strength, wear resistance characteristics, etc.), even complete the required function. Otherwise, it said the loss of the chain of products specified functions. Usually the loss of the product required function condition is called product "failure" of repairable products are often also known as "fault." It should be noted that for a required function in the same chain of products, are generally composed of a number of stainless steel lifting chain composed, arranged according to their order of importance. The so-called "capacity" is not only to define the meaning of work in the reliability of the quantitative requirements must also be galvanized lifting chain, in order to illustrate the degree of reliability of the product. This will improve the reliability of the chain and chain reliability compare similar products are an important basis. Since the chain fault should occur during the work with a chance, we can not only look at the case of a product, but rather to observe a large number of similar products or based on a certain number of sample test data, mathematical statistics after processing, in order to determine its reliability level. Therefore, the reliability of the definition of the "ability" to have statistical significance. G80 diameter of 16mm or less above grade Lifting chain 20Mn2,16mm using 25 Vanadium. g80 level lifting chain lifting chain is a high strength, high-intensity lifting chain is made of high-strength manganese steel, and 80 lifting chain just is made of high strength manganese steel, so He said 80 is a high-intensity lifting chain lifting chain. g80 level lifting chain automatic equipment from Germany, IF chain after heat treatment and strict control by the various testing equipment to ensure that G80 lifting chain, g80 level lifting chain with high intensity manganese steel produced, the production process strictly in accordance with ISO3077, EN818, AS2321 production standards, chain ensure safety factor of 4 times, 2.5 times the test load. 80 lifting chain surface can be polished, black, dipping, hanging plastic, electroplating and other processing to accommodate large moisture, acidic or slightly alkaline and other harsh environments.
