The Four Wheel Drive Of Conveyors – Chain Roller Conveyor

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-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 is what we call as the stick-slip resistance technology which is used in the system which not only prevents the load from slipping but also gives all the rollers on the bed a forward push.

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.

Although the method is expensive but for light loads and food packages this can be achieve easily by merely bending the bed into curves or loops. The conveyor can have a right angle transfer station or can be truncated 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 used should have high tenacity and normally they go through the process of controlled rolling for high toughness and strength. The choice of the material used in manufacture depends on the type of application.

A conveyor application used in the construction industry would be completely different than the one used in a chemical industry or a furnace. 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.

Other roller conveyors such as chain roller conveyors are one of the most popular and sturdy systems. Its application is in every industry right from transporting heavy loads to food packaging. Replace the chain with a belt and we have a chain belt conveyor which is used for very heavy and large loads. 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. For Indoor purpose, Plastic Conveyors are the best choice. They can be used for food packaging and suite all weather conditions. They provide a high level of cleanliness and are easy to maintain.

Check with the Chain Roller Conveyor manufacturers and your consultant before making the investment decision. And remember that all conveyors and related products have to conform to the standards set by the Government and the National Association of Conveyor Manufacturers.
