TYPES OF AGVs

AGV Towing Vehicles

• First type of AGV introduced.
• Towing vehicle is called an automated guided tractor
• Flatbed trailers, pallet trucks, custom trailers can be used.
• Generally, used for large volumes (>1000 lb) and long moving distances (>1000 feet).

AGV Unit load Carriers

• To transport individual unit load onboard the vehicle.
• Equipped with powered or non Equipped with powered or non-powered powered roller, chain or belt deck, or custom deck.
• Loads can be moved by Pallet truck, forklift truck, automatic loading/unloading equipment, etc.

AGV Pallet Trucks

• No special device is needed for loading except the loads should be on pallet
• Limited to floor level loading and unloading with palletized load
• Widely used in distribution functions
• Capacity 1000 Capacity 1000-2000 lb 2000 lb
• Speed > 200ft/min
• Pallet truck can be loaded either manually or automatically

AGV Forklift Trucks

• Ability to pickup and drop palletized load both at floor level and on stands.
• Pickup and drop off heights can be different
• Vehicle can position its fork according to load stands with different heights
• Very expensive
• Selected where complete automation is necessary/required.

AGV Light Load Transporters

• Capacity < 500lb
• To handle light and small loads/parts over moderate distances
• Distribute between storage and number of workstations
• Speed 100ft/min, turning radius 2ft
• For areas with restricted space

AGV Assembly AGVS Assembly-Line Vehicles Line Vehicles

• Variation of an light load transporter
• For serial assembly processes
• As the vehicle moves from one station to another, succeeding assembly operations are performed
• This kind provides flexibility for the manufacturing processes
• Lower expenses and ease of installation
• Complex computer control and extensive planning is required to integrate the system.
