In industrial production and construction work, it is often necessary to perform various operations with heavy or non-standard loads. In such cases, they rarely do without the use of special devices - slings. Their most versatile variety are special chains that combine the advantages of textile and rope products. There are various versions of such devices, characterized by certain parameters. The review presents the selection procedure and models of the best manufacturers of lifting equipment.
Content
A chain sling is a type of lifting device for working with heavy loads.
The main element is a piece of steel chain with links with a diameter of 0.7 to 3.2 cm, connected by welding. Transitional or end rings (detachable or non-detachable) are equipped at the ends to be equipped with hooks, brackets, lanyards.
When assembled, it has good flexibility and a large load capacity - over 60 tons. To improve anti-corrosion properties, zinc plating, thermal coating or enamels are applied.
The main purpose is the processing of heavy objects, including those with small surface curvature radii with sharp edges, etc., determined by increased wear resistance, flexibility and strength.
The design and characteristics allow the use of such devices with virtually no restrictions. They can be used in aggressive environments and high temperatures over 400⁰С.
Made of high quality steel with good anti-corrosion properties, chain slings are used in various fields:
For each equipment, a tag is issued indicating the operational parameters, date of testing, serial number, name of the manufacturer.In its absence, the use of the equipment is prohibited for safety reasons.
Prior to the start of work, an inspection of the equipment is carried out with the measurement of the diameter and pitch of the links.
