Different Types of Systems: Automatic Delivery

An alternative to manual distribution, automatic delivery dystems handle small loads 100 lbs. or less and are cost effective because there is no loading, unloading or waiting. They are used to handle pharmaceuticals and patient files in hospitals, mail and file distribution in offices, and inventory and file distribution in manufacturing facilities. Automatic systems employ either dumbwaiter or conveyor technology depending upon travel and speed requirements. The automatic dumbwaiter is regulated by elevator code (ANSI 17.1). Exempt from elevator code, the automatic conveyor is regulated by conveyor code (ASME B20.1)
