Chain Drive Roller systems are ideal for moving bulky and heavy packages, such as palletised goods. The chain-driven roller conveyor is the “four wheel drive” of the roller conveyor world! The chain-driven roller is all about power and traction. They use a stick-slip resistance technology which eliminates the slipping because of the low coefficient of friction. Hence, they are used to move very bulky and heavy packages like moving construction loads.

In a chain roller conveyor, the motor is connected by a chain which connects through a pair of drive rollers. Each Roller is connected to the other by a chain and sprocket layout. 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. As the distribution of the force can be controlled, the system can be used as an Accumulation conveyor by merely dividing the roller bed with two different motors with different torque. This is an expensive method and not widely used.

Unlike Gravity Roller Conveyors, they can be bended to form loops or curves but as the load weight and size increases the process becomes more expensive and harder to achieve. 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 is the traditional belt system for general warehousing, sortation and logistics. Gravity Roller Conveyor is Simple, economical unpowered roller system, typically used in warehouse environments. Line-Drive roller conveyor is used for lightweight movement of packages, boxes etc. perhaps with accumulation. It is Popular for bends and curves to complement powered belt conveyors.

Chain Drive Roller Conveyors is called as the “Big Daddy” of roller conveyor systems. It is used for transporting heavy or bulky items or pallets. Chain Drive Belt Conveyors are the belt equivalent of the Chain Driven Roller Conveyor. It is used for very large or heavy-duty conveyors. Accumulation Conveyor are very 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 are 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 suites any environment requiring high levels of hygiene, and ease of cleaning. They are most commonly found in the food industry.

Check with the Chain Roller Conveyor manufacturers and your consultant before making the investment decision. Make sure that the conveyors you are purchasing satisfy the standards set by the Government and the National Association of Conveyor Manufacturers.
