Chain manufacturing company

Our main manufacturing of chains are anchor studless chains, chains for lifting mechanisms, hardened chains, trawl chains and fork-shaped chains.

Round link chains Manufacturing

As a rule, steel (alloyed, high-alloyed, carbonaceous, etc., depending on the function of a chain), iron, metal alloys are used as a material.

There are two manufacturing processes:

  • Welding. A steel rod is cut into pieces (the length of such piece is the pitch of a chain), heated, bent, welded, and heat treated. In this way general-purpose chains and round link chains (GOST 7070-75) are produced.
  • Casting. This process is used to produce anchor chains, chains for material handling equipment (it is required to prepare an EPS mould).

The simplicity in design, high operational reliability and reasonable price of the round link chain explain why it is so popular.
Another advantage is a diverse assortment that includes the following types of chains.

Depending on the strength:

  • normal strength (lifting and hauling chains);
  • high strength (high-strength round link chains for conveyors, combines, mining equipment).

By the pitch against the thickness of a rod:

  • long link chains (they are lighter due to a long link);
  • short link chains (they can bear high loads due to the optimal ratio of the ring’s thickness to its size).

Depending on the accuracy of manufacturing:

  • calibrated chains with an acceptable pitch deviation of 1-2,5%;
  • non-calibrated chains with an acceptable pitch deviation of up to 4%.

Round link chains have a wide scope of applications:

  • To fix a heavy load during its transportation, anchorage, etc. ;
  • In various industries these chains are used at high operational loads as lifting and hauling chains in order to move loads.
  • Industrial round link chains are characterized by increased strength due to the use of alloy steel. For example, a 18х64 welded round link chain of strength class «C» is used in mining.
  • In conveyor and elevator production;
  • These chains are used to produce safety chains, car snow chains, well chains, chains for livestock, suspension equipment, tension bracing, and other products for everyday life, industry, and agriculture (TU 3148-002-55854806-2008 general-purpose round link chains).

Anchor studless chains.

An anchor studless chain is a constituent part of an anchor gear and serves to connect the anchor to the hull. However, today anchor studless chains are used not only in the fleet, but also for the needs of ocean oil platforms, floating docks, landing stages, barges, and other similar areas. Anchor studless chains are applied in many other economic sectors: mining and metallurgy, forestry and fishing, in agriculture, if the chains are subjected to heavy loads during operational use.

The anchor studless chain consists of a whole range of components, usually they are the first shot, several intermediate shots (the number depends on the length of a chain cable), the final (bending) shot and an end shackle, all of the components are joined together by Kenter links.

The anchor studless chain consists of high-strength forged or welded links and studs located in the middle. This construction eliminates even the slightest deformation of the chain under tensile loading.

The production of long chains (up to 350 m) is carried out by connecting 25-meter pieces of shots with the help of special detachable links. Small caliber chains (11-13 mm) are usually not divided into shots and produced solid.

The components of an anchor chain: common stud link, enlarged stud link, Kenter link, swivel, end shackles.

Welded round link chains

The chains of this type are applied in metallurgy, machine building, cement making, timber industry, agriculture, rigging, and also in individual farming. Welded round link chains are made of iron, steel (low-carbon, alloyed and high-alloyed), brass and other alloys. Finished chains can be tumbled, painted (with lacquer or enamels) or galvanized.

    • Variations in manufacturing and applications:
  • a long link chain of normal strength. It has good mobility, it is easy to shorten and lengthen, it is possible to make loops (“link into link”). As the size of a link increases, the weight decreases;
  • a welded short link chain of normal strength. Reducing the length of a link makes a chain more durable, adapting it to greater loads. Such chains can be used to suspend loads, for suspension equipment, for tension bracing, etc.;
  • round link chains for load lifting mechanisms – high-quality wear-resistant chains for sprockets (DIN 5684);
  • welded non-calibrated chains for general use (DIN 5687) – used for the manufacture of chain slings (quality classes 5 and 8).

Cargo and traction chains

Lifting and hauling chains are an indispensable tool for moving large loads, rigging, and other similar operations. The strength of such chains is almost triple the one of metal cables with the same diameter. Lifting and hauling chains are traditionally used in conveyors, escalators, bucket elevators, coal-mining machines, machinery with motor and hand drive, various branches of animal husbandry, timber, oil, and fishing industries.

    • Advantages of lifting and hauling chains::
  • high wear resistance and strength,
  • it is possible to sling load with sharp edges,
  • flexibility and mobility, simple repair;
  • resistant to a hostile environment,
  • service life is not less than 10 years.

Testing and calibration

All products that are manufactured for conveyors and transporters undergo durability tests by modeling an applied dynamic load. The enterprise undergoes regular verifications and attestations by technological supervision agencies and has certificates of product conformity with the safety requirements. The manufacturer produces chains and components for rotary kilns by using flash welding in compliance with the requirements of European norms and standards, according to the technology developed in conjunction with our partners.
