Modular belt conveyor are a middle ground between belt conveyors and chain conveyors. A modular belt consists of individual plastic modules usually linked together with joint rods. This modular belt is driven by chain spockets; the base frame of the conveyor is constructed on standard profile supports.

The modular belt makes it possible to accept hot workpieces or workpieces with sharp edges. Furthermore, large conveyor widths can be implemented without high pre-tensioning of the belts. However, in contrast to chain conveyors, this design is less maintenance-intensive and is a technically simpler solution. These systems are frequently used as cooling lines, since the chain modules can be designed to be permeable to air.
