1) AGVS

An Automatic Guided Vehicle System, or AGVS consists of one or more computer controlled wheel based load carriers (normally battery powered) that runs on the plant floor (or if outdoors on a paved area) without the need for an onboard operator or driver. AGVs have defined paths or areas within which or over which they can navigate. Navigation is achieved by any one of several means, including following a path defined by buried inductive wires, surface mounted magnetic or optical strips; or alternatively by way of inertial or laser guidance. See also SGV , Self Guided Vehicle , Unit Load AGV , and/or Tugger AGV .

2) Air chain hoist

A pneumatically driven machinery unit, utilizing chain as its lifting medium, and used for the lifting and lowering of a freely suspended (unguided)load.  Often used in environments that require electric spark avoidance due to a potentially explosive atmosphere.

3) Air hoist

A suspended machinery unit that is powered by pneumatically driven motors and is used to lift or lower a freely suspended (unguided) load.  Generally uses chain or wire rope as its lifting medium.

4) Air wire rope hoist

A pneumatically driven machinery unit, utilizing wire rope as its lifting medium, and used for the lifting and lowering of a freely suspended (unguided) load.  Often used in environments that require electric spark avoidance due to a potentially explosive atmosphere.

5) Automated dispenser

A series of vertical product dispensers which kick individual units of products out the bottom onto a conveyor.

7) Carrier

Also known as a trolley.  A unit that travels on the bottom flange of a monorail or patented track beam, jib crane or bridge girder to transport a load. Also refers to a trucking line used to transport materials to and from a distribution center.

8) Chain conveyor

A form of powered conveyor used to transport heavy unit loads such as pallets and industrial containers. These conveyors can be single or double chain strand in configuration. This chain is not only the driving force but it is also the part which comes in direct contact with the load and provides friction which pulls the load forward. In some cases, free rollers on either side of or between the chain provide additional support to the load. Short sections of double strand chain conveyors are a common means of transferring loads at right angle to/from another straight section of roller conveyor.

9) Chute conveyor

The chute conveyor is the simplest example of gravity operated conveyor. Not unlike a child's sliding board, unit simply slides down a straight or spiraling metal or plastic chute to it ultimate destination.

10) Closed shelving

Shelving with the sides and back of the unit enclosed with sheet steel side and back panels.

11) Double row, double face shelving

One generally continuous row of units joined together, back to back and side to side to be serviced from two service aisles.

12) Drive in rack

This type of rack utilizes upright frames, rails, and ties to allow a vehicle to enter a storage rack structure from one side only and pick up or deliver pallets on continuous rails.  Drive-in rack is used to address repetitive products and serves to take advantage of cubic space available for storage, when such unit loads do not lend themselves to block stacking.

13) Electric Hoist

A suspended machinery unit that is powered by electrically driven motors and is used to lift or lower a freely suspended (unguided) load.  Generally uses chain or wire rope as its lifting medium.

14) Exchange pallet

Refers to a pallet that is used by several shippers whose ownership is transferred when the ownership of the unit load is transferred.

15) Fixed Aisle Storage & Retrieval

Fixed Aisle (F/A) Storage & Retrieval Systems consist of one or more long, narrow aisles framed on both sides by a steel (and sometime extruded aluminum) storage rack structure into and from which loads are automatically stored and retrieved under computer control. The storage/retrieval function in each aisle can be performed a variety of ways.  However, the most  common was is by a machine that consists of a floor running, traveling structural frame or vertical mast that guides and supports a hoisting carriage on which loads are carried. One or more shuttles or insertion/extraction devices on the hosted carriage manipulates loads into and out of adjacent or opposing storage rack positions. All three machine motions; horizontal (down aisle), vertical and shuttle action are independently and automatically controlled.
