Guaranteed for heavy-duty operation

One reason for the superior performance of Kopar forged conveyor chains is the used special steel alloy with boron addition and the heat-treatment process that results in hardening throughout the entire link. Therefore Kopar conveyor chain maintains its properties even under demanding operating conditions and withstands wearing better than traditional forged conveyor chains made of case-hardened steels.

Selection and justification of appropriate chain material

Tailor-made industrial chains not only guarantee that the chain meets the demands set by your process and conditions, but they also guarantee the lowest operational costs (OPEX) and the lowest total costs of ownership.

The most widely used chain link material in industrial applications worldwide is case-hardened manganese steel (20MnCr5 / EN 1.7147). The main reason being its price. However when calculating the total cost of ownership in stead of focusing merely on the cost of purchase you will agree that replacing manganese chain links with Kopar’s boron steel ones makes all the sense.

Although boron steel chains are slightly more expensive to purchase, approximately 50% more than the traditional manganese chains, the lifetime is significantly longer! Double, triple and even quadruple lifetimes mean huge savings in both money and time resources.

We strongly favour the tempering steel with boron addition (27MnCrB5 / EN 1.7182) due to its multiple lifetimes and, thus, the clear benefits it brings to users of conveyor chains.

For extremely special cases we supply chains made of stainless steel (AISI 420 / EN 1.4034) for harsh chemical conditions and heat resistance steel (1.4713) for those applications which continuously operate at temperatures up to 700 °C.

Continuous maintenance

Anticipation is the key to keep your drag chain conveyors up and running without unplanned stops.

We have developed a practical tool to measure elongation easily and as often as you want. This straightforward procedure guarantees the maximum lifetime of the chain and minimizes the risk of breakage and unplanned corrective maintenance.

We recommend changing the chains when the elongation has reached 2,8%. The sprockets are to be replaced at the same time the chain is renewed to ensure optimal operation of your process.

Looking for a replacement?

Each material handling application is unique and requires specific conveyor chain to perform its conveying task in an optimal way.

All Kopar conveyor chains are assembled to order. The type of the link as well as the amount and location of flights is decided based on the characteristics of transported material.

In order to provide a quotation, we require the following information:

  • chain type in use
  • width of the chain or width of the conveyor
  • type and shape of flights
  • pitch of flights

Of highest quality

We have been awarded the Key Flag symbol that proves Finnish quality, competence, and know-how. Companies worldwide use our key ticketing product, a conveying chain.

Before shipping the chains to run our clients’ facilities worldwide, the chains undergo a rigorous QA process. We continuously improve our designs to ensure the most durable solutions that keep things running smoothly and your expenses low.
