100 chain rigging made of special materials manufactured under the same intensity 25% higher than the diameter 80, lifting chain process, and 120 chain strength higher than 100 by 25%. 1.100 is super-type chain rigging chain rigging, compared with 80 chain, super-type biggest advantage is in the same diameter, the rated load of up to 25%, that is at the same rated load, 100 Its diameter is smaller chain level. 2.100 chain rigging meet all the requirements of European standard EN818-4. 3.100 chain rigging surface has a higher hardness and better toughness. Chain links and attachments more wear. 4.100 chain rigging system can not be mistaken, because only chains and accessories have the same level in order to connect to each other. 5.100 chain rigging can break elongation least 20%. 6.100 chain rigging temperatures up to 200 degrees = 100% of the rated load of 200 degrees to 300 degrees = 90%, 300 degrees to 400 degrees = 75% of the 7,100 grade chain rigging by the DIN EN ISO 9001:. 2000 Quality performance management system to ensure the quality of the chain. In addition, by a third party inspection agency to conduct regular monitoring of production. 8.100 chain rigging are marked with the words "8E" by industry associations to give the highest level of official mark. Each slip ring hoist chains, usually the best ingredients cooked welding scales oval, wrought iron is the most able to withstand shock, sometimes on short-necked oval slip ring plus welding a short column, Dongguan lifting chain to increase its strength, the slip ring, becoming a cylindrical ring, lifting the supply chain, its strength is relatively short column of no more than opening 20-25% of the ring. This indicates that the chain pulley, even the chains represent even chains formats, lifting chain where cheap goods when the mechanism of iron, not very sophisticated, faster than 180, can not be applied. Large tonnage lifting chain, lifting chain chen (certified), Dongguan lifting chain sling from Hebei chen Manufacturing Limited. Hebei chen sling Manufacturing Co., Ltd.
