Chain Sling is a metal chain linked to the sling, in accordance with its form is mainly welded and assembled two kinds, according to its structure single and many, and so on, the use of high-quality alloy steel, its outstanding features are wear-resistant, high temperature, low ductility, Chain Sling force will not be stretched, etc. Its service life is long, easy to bend, suitable for large-scale, frequent use occasions. Flexible multiple limbs, a variety of combination forms can improve work efficiency, reduce costs.
Chain slings and cables are widely used in ports, electric power, steel, shipbuilding, petrochemical, mining, railway, construction, metallurgy and chemical industry, automobile manufacturing, engineering machinery, papermaking machinery, industrial control, logistics, large transportation, pipeline auxiliary, Chain Sling airport construction, bridge, aviation and spaceflight, etc.
Chain slings are super-type chain rigging, compared with the 80-level chain, the super strength of the largest advantage is in the same diameter, its nominal load is 25% higher, that is, under the same nominal load, the 100-level chain is smaller in diameter.
Chain slings meet all requirements of the European standard en818-4.
The surface of the chain sling has higher hardness and better toughness. Chain links and accessories are more anti-wear.
The tightness of chain slings should be suitable, Chain Sling too tight to increase power consumption, bearing easy to wear, too loose chain easy to beat and off the chain. The degree of tightness of the chain is: from the middle of the chain lift or pressure, the two sprocket base distance of about 2%-3%. The sprocket should not be tilted and swung on the shaft. In the same transmission assembly, the end face of the two sprocket should be located in the same plane, the sprocket base is 0.5 meters from the following, the error of 1 mm, Chain Sling the sprocket base from 0.5 meters, the promise error 2 mm. But do not promise to have friction chain sprocket wear after severe, should simultaneously replace new sprocket and new chain to ensure outstanding meshing. Chain Sling You cannot replace new chains or new sprockets alone. Otherwise, the meshing is not good to accelerate the new chain or new sprocket wear. Sprocket tooth surface wear to a certain degree should be in time to turn the surface use (refers to the use of adjustable surface sprocket). To extend the use of time.
