Carousel conveyors are also configured as loops, either in an oval or L – shape. Typically, parts are held on pallets, which are free floating on the system as these conveyor runs in a continuous loop. This type of system offers a variety of cost savings advantages. First, only about half the length of the chain is used when compared to a conventional conveyor system. This reduces the amount of replacement chain kept on hand for emergency purposes and cuts down on the initial cost of the conveyor. Fewer drives, motors, and controls are used when compared to a traditional conveyor system. This all reduces the amount of equipment and controls needed, thus providing economical solutions and lesser space for operations.
