The Chain Sling Mainly Has Two Kinds Of Welding And Assembling

The tightness of chain slings should be suitable, 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, Chain Sling the error of 1 mm, 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. You cannot replace new chains or new sprockets alone. Otherwise, the meshing is not good to accelerate the new chain or new sprocket wear. Chain slings should be worn to a certain extent after the application (refers to the use of adjustable surface sprocket). To extend the use of time.

High-strength chain sling is a sling made of metal chain link, according to its form, there are two kinds of welding and assembly, Chain Sling according to the structure of the single limb and multiple limbs, and so on, the use of high-quality alloy just, its outstanding features are wear-resistant, Chain Sling high temperature resistance, corrosion resistance, low ductility, the force will not be stretched and so on. Its service life is long, easy to bend, suitable for large-scale, frequent use occasions. Flexible multiple limbs, a variety of combinations can improve work efficiency, reduce costs. Chain and chain sling use methods and precautions;

Chain slings before use, must see the signs on the work load and applicable scope, strictly prohibit overloading use, and the chain sling do visual inspection, in line with the rear can be used. In the normal use situation, the hoisting angle is the key to influence the load, the hoisting angle is no more than 120 °, otherwise it will cause the chain rigging to be partially overloaded. Chain Sling The carrying chain rigging is forbidden to be attached directly to the hook piece of the crane hook or to the chain of the hook, which prohibits the use of irregular connecting parts. When the chain sling is surrounded by the hanging object, the edges need to be padded to prevent the ring chain and the suspended material from being damaged. Temperature has a certain effect on the use of chain rigging.

In lifting chain sling inspection should pay special attention to the frequent use of the hook as far as possible to do a quarterly inspection. The detection content mainly guarantees hook body and dangerous Section two aspects. In the hoisting Sling Hook carries on the inspection first uses the kerosene to wash the hook body, uses 20 times times the magnifying glass to check whether the hook body has the crack, if discovers the crack should stop using replaces the new hook. When the height of the dangerous section is 10% of the original height, Chain Sling it needs to be replaced in time.

1. When choosing a chain sling, it is necessary to purchase a qualified product with safety proof and cannot use unqualified products.

2. If the chain slings are homemade, Chain Sling they should conform to the quality requirements of the state and the industry, and their technical indicators shall not be lower than the national and professional standards.
