Short link chain 5.0 mm stainless steel A4 DIN 766 is mainly used as a fastener in the installation of various structures. Also, the short-link chain has found wide application in the sphere of the national economy. A chain can be used to fence, fasten or hang something. To prevent the negative impact of the environment and extend the service life, the chains are coated with a layer of zinc.
The material from which this chain is made is high-quality stainless steel, which is resistant to acid environments. The product does not lose its properties in salt and chlorinated water, and is also not afraid of high temperatures.
The chain complies with the modern European standard DIN 766.
This type of rigging consists of round rings or ovals with a length to width ratio of less than 3: 5. Round link chains are characterized by increased strength. With the same link caliber, such a chain will withstand a greater load than a long-link one. In addition, they are less likely to deform parts in a bend, which makes it convenient to wind on a drum. Anchor chains can also be attributed to structures with a short link with additional spacers. Short-link rigging is less tangled when stacked in a container.
Currently, metal chains, consisting of oval (rounded) links connected by a welding machine, have gained wide popularity among a wide variety of fasteners. The reason for the demand is a versatile purpose. They can be used for both domestic and industrial use. Depending on the purpose, the chains are divided into economic and technical. As a rule, round-link chains are used for moving, holding, hanging loads, as well as in load-gripping mechanisms in the form of separate elements.
Steel chains are used at construction sites, warehouses, industrial shops, transport organizations. One way to use chains is to hang the hooks of large lifting machines.
The short link chain is a popular type of rigging used for stretching. According to the requirements of the International Standard DIN 766 (analogous to 5685A), it is available calibrated and uncalibrated. Such a chain is made from bars of alloyed, carbonaceous, high-alloyed steels of various diameters and has a galvanized coating in the form of a layer of zinc.
short-link welded chainThe size of the chain is determined by the caliber of the link (diameter of the section of the rod). Chain links differ from each other in length, width and caliber (diameter).
The short link chain has a shortened link, so it is designed for increased loads and is considered more reliable and durable. But it is not recommended to use it for lifting cargo. Supplied in coils, which are wound on plastic coils from 10 meters to 60 meters long. The length in the coil depends on the diameter of the link.
The chain is short. Applications:
mechanical engineering;
shipbuilding;
automotive industry;
warehouse technologies;
Agriculture;
construction sector.
When choosing a specific steel chain, you need to know the following characteristics:
breaking load - the maximum load that a short-link metal chain can withstand before destruction during tensile tests;
working load - the largest mass that can be hung on the chain in the conditions of its operation;
chain pitch - the inner length of the link at its widest point.
The chain is short. Mounting method
The chain is installed using auxiliary rigging elements: carabiners, turnbuckles, swivels, chain connectors and other connections.
Welded short link chain has a wider range of applications - from light hand-type hoists to heavy lifting cranes. Links using butt resistance welding are made in one joint. After manufacturing, the chain is subjected to a weld inspection and proof load test. It works great for stretching and has a small stretch factor. The design of the chain allows you to freely adjust the length and has a relative degree of freedom limited to just one link, as well as create a loop using the "link to link" method.
First things first, the chain can act as a component of another more complex device. For example, chain slings or chalk slings. With the help of such a spider-like chain connection, it is fixed to the structure being lifted or moved by brackets or hooks.
Steel cable DIN 3055 is often used for stretching. A big advantage of a welded chain over a cable is that it does not fray at the bends. To avoid this problem, staples are provided for the cable. Or they use a short-link chain, the price of which will be the second advantage over the cable. The production of a chain connection is less expensive and technologically simpler, which affects the cost.
766 DIN also has an important characteristic - strength, namely the absence of brittleness. When exposed to a load, the material of the product will, of course, be deformed - stretchingtsya. But thanks to the technological process in the manufacture of the chain, it will not collapse as a fragile product. Each standard size corresponds to its own value of working and breaking load.
The wire from which the links are made is first heat treated. The bend into an elongated ring occurs while the metal is in a soft state, and then the temperature decreases smoothly. For comparison, swords and knives, on the contrary, are hardened by sharply alternating cold and hot environments. If you apply force to the knife at some point, it will break from fragility. The chain begins to gradually stretch and, with excessive exposure, will break.
Both long-link and short-link chains will be mandatory for the assortment in stores. This is relevant for areas located near rural farms: installing devices for moving and raising structures, keeping cattle and other livestock, and creating restrictive structures. The consumption of chains will be different, which means that in a fastener and rigging store you can buy a DIN 766 chain in coils of 100 m, 50 m or 10 m or in linear meters.
Often, a 6 mm short link chain is bought by manufacturers of decorative products. The attractive shine of galvanized metal makes the din 766 chain an excellent option as a decorative element in the design. Chains with link diameters of 4 or 5 mm are also actively used in the decoration of structures.
