Lifting chain: often a metal ring or donut chain lifting chain summary: high strength lifting chain, imports lifting chain, lifting chain shackle regulator. The company lifting chain, chain rigging complete specifications, lifting chain quality guaranteed. Lifting chain is made of alloy steel and heat treated for disorders traffic channel chain-shaped objects (such as in the streets, river or harbor entrance) chain can be divided into short pitch precision roller chains, short pitch precision roller chains, heavy-duty transmission with a bending roller chain, cement machinery with a chain, plate chain of high-strength chain of high-strength chain rigging series, professional support for engineering, manufacturing facilities, production lines supporting the use of complementary and special environment. A connecting member to define the subject matter crane or hoist sling and was hanging between objects are also covered by the sling and spreader collectively Second, the classification sling: sling mainly metal and synthetic sling fiber sling two categories. 1. Metal sling are: wire rope slings class, chain slings class, shackle type, hook type, hanging (folder) pliers, magnetic spreader etc. 2. synthetic slings are: to nylon, polypropylene, polyester, high strength and high modulus polyethylene fiber rope for material production and belts sling Third, choose a sling: when selecting a sling specifications, must be the size of the load lifting, weight, shape and hoisting methods to be adopted common usage coefficient calculation takes into account the impact of the inclusion, the work force is required to give the limit, while the working environment, the type of load must be considered. You must select both sufficient capacity, but also to meet the proper length of usage of sling, if more than one is used simultaneously lifting sling load, you must use the same type of sling; flat sling material can not be subject to environmental or loading effects. Whether or soft attachment lugs need to be carefully considered the last paragraph and auxiliary accessories and lifting equipment sling match. Fourth, the sling safe use: Do not overload, unmarked sling confirmed late may not be used. Parts sling combination of components on a combination of components according to the requirements of regular inspections. The method should not be used to correct the hammer has distorted spreader. Sling prohibit throwing. Do not pull or let the heavy rolling in a sling from a heavy object. Chain rigging is made of metal chain link connecting rigging, there are two main types of welding and assembly in accordance with its form, its structure alone, and more than just the like, using high-quality steel, it features a wear-resistant, high temperature the ductility is low, not by the force such as elongation. Its long life, easy to bend, for large-scale, frequent use of the occasion. Flexible multi-limbed, various combinations can improve efficiency and reduce costs.
