Chain rigging is made of metal chain link connection rigging, there are two main welding and assembly in accordance with its form, its structure alone and more than two, etc., using high-quality steel, it features a wear-resistant, high temperature ductility low, after the force will not stretch like. This high-strength chain rigging can be divided into those levels: the chain is divided into 120 chain rigging, chain rigging 100 and 80 rigging. 100 chain rigging made of special materials manufactured under the same intensity 25% higher than the diameter 80, and 120 chain strength higher than 100 by 25%. China's lifting equipment plant mainly produces or 80 lifting chain rigging, lifting chain, like 100 and 120 rigging lifting chain rigging manufacturers is still very small, this advanced lifting chain rigging main some large foreign manufacturers will be able to produce this special high-strength material lifting chain. 1,100 level is super-type chain rigging chain rigging, compared with 80 chain, super-type biggest advantage is in the same diameter, up to 25% of its rated load, galvanized lifting chain, that is, said at the same rated load, 100 chain its smaller diameter. 2,100 grade chain rigging surface has a higher hardness and better toughness. Chain links and attachments more wear. 3,100 grade chain rigging temperatures up to 200 degrees = 100% of rated load, lifting lifting chain, 200 degrees to 300 degrees = 90%, 300 degrees to 400 degrees = 75% 4,100 grade chain rigging elongation at break least be 20%. 5,100 grade chain rigging system can not be mistaken, because only chains and accessories have the same level in order to connect to each other. Lifting equipment is used in most of the sling lifting chain, but a chain of drawbacks is susceptible to rust and rusty chain-related equipment after very bad for our normal operations are unfavorable, so we need to learn antirust . In fact, the chain of corrosion protection is very simple, as long as we avoid wet working environment can, if forced to operate under special circumstances, that we would just wipe the chain after use a clean and dry, then apply a layer lubricants, lifting chain prices, the thickness of the lubricant should be appropriate, no protection is too small, too much can also play a counterproductive. Lifting chain rust is a very deep knowledge, that it is relatively simple, in fact, inside there are a lot of details need to pay attention, if not pay attention to detail, our work is wasted, Quzhou lifting chain, pay attention: the chain We must pay attention to the gap at the special treatment, which we most easily overlooked, and is the most dangerous place. Lifting chain rigging, lifting chain samples (certified), Quzhou Hebei Chen force by the lifting chain sling Manufacturing Limited. Hebei chen sling Manufacturing Co., Ltd. (www.qzhon.com) Hebei Baoding, chains, sprockets 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.
