Conveyors are used because they are fairly easy to design and maintain, and the variety of conveyor systems available allows for them to fulfill different
roles. In production plants with assembly lines, a standard belt conveyor can
often be a simple method of transporting goods along the production line, a
much more efficient solution than manually transporting equipment or
materials to each production station one-by-one. Conveyor systems are
even chosen above other mechanized or automated methods of conveyance.
