Chain Roller Conveyor

In a chain-drive conveyor, each roller is bound to its neighbour by a chain-and-sprocket arrangement, terminating in a pair of "driver rollers", which also connect to the motor by chain. This arrangement ensures that no roller can 'slip' under load, and gives positive drive to all of the rollers on the bed simultaneously.

Unlike most conveyors, the motor on a chain-drive roller conveyor is usually centrally-mounted, as this allows a more even distribution of torque across the roller bed as a whole. It is still possible to create an accumulation system with this technique, merely requiring that the roller bed be divided into separate sections, each with its own drive motor and suitable sensors. At medium weights and package size, it is still possible to have bends and loops, but these become increasingly impractical and expensive as weight/size increases. Instead, a right-angle transfer station or turntable can be used to accomplish the same effect.

Chain Roller Conveyor, including its parts like sprockets, pins, rollers and, sleeves or plates, can be made from carbon steel, stainless steel and plastic. Steel parts are normally heat treated for greater toughness. The choice of the material used in manufacture depends on the type of application. A system meant for the mining industry, for instance, would be different from the one that is installed for a tire factory. For bakery or vulcanizing operations the chain rollers has to withstand high levels of heat. In a freezing plant the conditions are just the opposite.

Belt Conveyor: The traditional belt system for general warehousing, sortation and logistics.

Gravity Roller Conveyor: Simple, economical unpowered roller system, typically used in warehouse environments.

Line-Drive roller conveyor: Lightweight movement of packages, boxes etc. perhaps with accumulation. Popular for bends and curves to complement powered belt conveyors.

Chain Drive Roller Conveyors: The "Big Daddy" of roller conveyor systems; for transporting heavy or bulky items or pallets.

Chain Drive Belt Conveyors: The belt equivalent of the Chain Driven Roller Conveyor; used for very large or heavy-duty conveyors.

Accumulation Conveyor: Popular in packaging, warehousing, food preparation, and a wide range of industries where products must be brought to a halt at the end of the conveyor, without halting the entire conveyor.

Wire Mesh Conveyors: A lightweight variant of the chain-mesh conveyor, useful when the products need to be drained, or to have warm/cool air circulated around them.

Plastic Conveyors: Any environment requiring high levels of hygiene, and ease of cleaning. Most commonly found in the food industry.
