A conveyor system is a common piece of mechanical handling equipment that moves materials from one location to another. Conveyors are especially useful in applications involving the transport of heavy or bulky materials. Conveyor systems allow quick and efficient transport for a wide variety of materials, which make them very popular in the material handling and packaging industries.

Conveyor Safety Standards. Conveyor safety standards address safety considerations in design, testing, and use, doing so with a focus beyond other standards that primarily address proper functioning with safety as an indirect result as proper functioning is of course safe functioning. These conveyor standards focus specifically on safety.
