Drop forged link chains

Drop forged link chains are especially suitable for dusty, rough and abrasive operating conditions. Drop forged link chains are commonly used in bottom ash, coal and cement conveyors, but are also suitable for conveying grain or wood chips.

Like normal conveyor chains, drop forged link chains can be equipped with various scrapers or attachments and can also be used as double chains with flights.

By using heat resistant raw materials, drop forged link chains can be used in environments over 800 degrees of Celsius.
