A range of heavy-duty conveyor chain specially designed for harsh environments is now available in the UK from Letchworth-based FB Chain Ltd. Made in Finland, where it has been used to power conveyors working in the demanding timber and wood industries, the chain's pins and bushes are welded to the side plate, unlike a standard chain where the pins and bushes are usually simply riveted in place. According to FB Chain, the welded construction method results in a chain with a breaking load some 30% higher than the riveted alternative.
