There are various types of drive units that are available to move the conveyor chain.

End drive units pull the chain from one end of the conveyor. The chain returns on the bottom of the conveyor beam, passing through an idler end at the other end.

Combined drive units are those that have a drive unit and an idler end together in one unit.

This is used in areas where transfer from drive unit of one conveyor to another of the same size is required. The transfer area is provided with either steel plate, gravity transfer rollers or powered transfer rollers depending on product type and length.
