A chain-driven roller conveyor, also called a pallet conveyor, is the most robust type of chain conveyor. Every section of the conveyor features an electric motor, which powers a roller. The transmission between the rollers is achieved by means of a roller on roller transmission. This is enabled by a dual sprocket head on each roller. The rollers are connected to the adjacent rollers by a chain. Chain-driven roller conveyors are excellently suited to transporting heavy loads. Using the chains, relatively strong torques can be transmitted along the rollers.
