Chain conveyors are continuous conveyors for the transport of piece goods (e.g. pallets or lattice boxes ) or bulk goods (e.g. sand , coal or flour ). They belong to the load handling devices in conveyor technology . A chain conveyor consists of one or more circulating chain strands on which the goods to be transported lie. The drive sprockets are connected to one another via a shaft. The chain drive is driven by an electric motor, which is usually controlled in two stages (creep and main speed).

Chain conveyors survey will be required when the loading equipment can be transported on conveyor belts because of its requirements in the conveying direction anymore. A Euro pallet z. B. can easily be transported lengthways on a roller conveyor, as there are always three boards on all rollers; In the transverse direction, transport via chain conveyors is necessary because the support on the rollers is too small due to the openings for the fork prongs .

Chain conveyors for bulk goods have the advantage over conveyor belts that they can be made dust-tight, but such long conveyor routes cannot be bridged and the power requirement is greater because of the higher friction.

There are basically two types of work for the chain conveyor:

scratch
Here the chains run outside of the conveyed goods
Trough conveyor
Here is the chain in the goods
