Technical features of welded chains
A useful invention has not lost its relevance in modern society. Sufficiently versatile, depending on the physical dimensions and material, it can be used both in industry and in everyday life. Quality welded chains https://up-lift.ru/ are strong enough to last a long time resist physical stress. They have proven themselves in operation, well resist a significant temperature difference.
Scope of application of welded chains
The industry produces several types of industrial circuits. Their main feature is tensile stability. They retain their strength, regardless of the applied effort. Most often, cargo and traction welded chains are used in the following areas:
- As slings for various lifting mechanisms.
- For holding goods in a static position in railway and ship transport.
- There are models of winches with chains instead of ropes.
- As insurance on crane slings.
Minimum wear and tear allows the use of chain-based rigging for several years, without the risk of an emergency during unloading and loading operations.
Classification of welded chains
In order for the chain to be as practical as possible, it must be selected from a fairly large assortment from the manufacturer. In addition to short and long links, the classification takes into account other design features:
- minimum breaking force;
- quality class of steel used;
- section diameter of the wire used;
- weld strength;
- step, length of each inner link.
Calibrated chains are more accurate. The raw material used is a bar with a constant cross section. Most often they are used in lifting mechanisms, where the accuracy of each link is critical. Uncalibrated chains are in no way inferior in strength to analogues, but may have deviations within small limits, both in pitch and in cross-sectional diameter.
