Chain conveyors use an endless chain both to transmit power and to propel material through a trough, either pushed directly by the chain or by attachments to the chain. The chain runs over sprockets at either end of the trough. Chain conveyors are used to move material up to 90 metres (300 ft), and typically under 30 metres (98 ft). [1]: 271
Multi-strand chain conveyors are used for double-pitch roller chains. Products that cannot be moved on traditional roller conveyors can be moved by a multi-strand chain conveyor. Chain and roller conveyors are short runs of two or more strands of double-pitch chain conveyors built into a chain-driven line roller conveyor.
An example of a standard type chain with cables running through it. Cable carriers, also known as drag chains, energy chains, or cable chains depending on the manufacturer, are guides designed to surround and guide flexible electrical cables and hydraulic or pneumatic hoses connected to moving automated machinery.

The gear is turned, and this pulls the chain putting mechanical force into the system. Another type of drive chain is the Morse chain, invented by the Morse Chain Company of Ithaca, New York, United States. This has inverted teeth. [2] Sometimes the power is output by simply rotating the chain, which can be used to lift or drag objects.
The ratio of the output force to the input force is known as the mechanical advantage of the linkage, while the ratio of the input speed to the output speed is known as the speed ratio. The speed ratio and mechanical advantage are defined so they yield the same number in an ideal linkage.
2. Solid bearing pin chain. Solid bearing pin chain has the same dimensions as hollow bearing pin chain but is more robust and thus suitable for more arduous conveyor applications. 3. Deep link chain. Deep link chain has deeper side plates than the normal chain plates and so provides a continuous carrying edge above the roller periphery.
The cam mechanism was further improved in 1925 by eliminating the drag chains for the shoes and changing to a cam wheel running in an oval track. This gave the shoe a proper elliptical motion. [ 6 ] [ 7 ] The first dragline using the new mechanism was the 3-W available in 1926.
