Conveyor systems are equipment used to move materials, components or finished goods between locations within a workplace. Businesses in this category may design, manufacture, supply or install systems for factories, warehouses, distribution centres, airports and other settings where items need to be transported along a set route. The equipment can be built for light packages, heavy loads, bulk materials or particular handling requirements. Common types include belt, roller, chain, screw, slat and overhead conveyors, as well as systems that use air to move materials through pipes. Suppliers may provide motors, frames, rollers, belts, controls, sensors, safety guarding and equipment for sorting, merging or diverting items. Systems can be configured for straight or curved routes and may connect with storage, packing, production or automated handling equipment.
