Drive unit for a conveyor system comprising a conveyor chain made up of wheeled links connected together end to end and having load carriers depending therefrom. A pair of endless driving chains, each of which extends around a pair of sprockets, are positioned in parallel planes, one on each side of the conveyor element. One sprocket of each pair is driven from a motor, via a self-adjusting pulley and an overload clutch. U-shaped carriers are secured between the driving chains and carry drive dogs arranged to engage from above and drive the conveyor chain when the driving chains are travelling parallel to the conveyor chain.
