46) Truss girder crane
An overhead traveling crane designed with structurally reinforced bridge girders to allow greater span and loading capabilities. The reinforcement consists of utilization of trusses extended vertically and horizontally from the load bearing beam(s) of the crane bridge.
47) Push type crane
An overhead traveling crane whose horizontal travel is powered manually or by the operator. Often work station cranes are push type cranes. This crane may or may not utilize powered hoist or lifting mechanisms.
48) Horizontal Carousels
As a storage device, a horizontal carousel consists of a fixed number of adjacent storage columns or bays that are mechanically linked to either an overhead or floor mounted drive mechanism to form a complete loop. Each column is divided into a fixed number of storage location or bins which in most applications are constructed of a welded wire frame. Loads consisting of containers or totes may be inserted and retrieved either manually or by an automatic inserter/extractor mechanism. However, rotation of the carousel, whereby a specific storage location is brought to the picking location, is almost always controlled automatically. See also Vertical Carousel , Vertical Lift Module , Rotary Rack , and/or AS/RS .
49) Rotary rack
A rotary rack is a special variation of a horizontal carousel. In this case each vertical level or storage location is mechanically independent of the location above or beneath it. Each level in turn is driven by a separate and independent drive. Therefore, simultaneous, independent rotation of each level is possible (in any direction). Although replenishment and picking can be accomplished manually, most rotary racks incorporate automatic load inserters and extractors. See also Horizontal Carousels and/or AS/RS .
50) 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. See also Carousels , Unit Load AS/RS , Mini-Load AS/RS and/or Micro Load AS/RS .
51) Vertical Carousels
As a storage device, a vertical carousel provides for closed loop automatically controlled rotation of the basic storage unit, which in this case may be a shelf that can be subdivided into multiple bin locations. However, a shelf or a given vertical position need not be divided in order to handle large items such as a bolt of fabric or a roll of carpet. Because storage is vertical, such systems are popular when conserving floor space. Although automatic insertion and extraction of individual items or loads is possible, it is not as common as it is with horizontal carousel applications. See also Horizontal Carousels and/or AS/RS .
52) Vertical lift module
A Vertical Lift Module, or VLM is a storage system that consists of two parallel columns each of which is divided into fixed shelf locations that can hold a single storage module such as a tray or tote. The shelving locations are single deep. A tray or tote is inserted, extracted and transported between storage levels and picking locations via an elevator-like device with an automatic shuttle that travels up and down within the space between the storage columns. See also Carousels and/or AS/RS .
53) Shelving post system
The vertical upright member that supports the horizontal shelf. Posts are manufactured in a variety of configurations.
A conveying system which consists of monorail track, track mounted electrification, individually powered vehicles, a supporting structure, a control system, lifts, switches and turntables.
Generally constructed of plastic, metal or wood, a pallet is a piece of transportation/movement equipment utilized in the movement of unit loads. Usually "fork-liftable" in that it is designed to accept forks between the top and bottom platforms of the unit.
A portable, horizontal, rigid platform used as a base for assembling, storing, stacking, handling and transporting goods as a unit load, often equipped with a superstructure.
56) Dock lift
A lift whose travel is generally 5 feet (1524 mm) or less and which is primarily used to load/unload material from trucks and transfer it to dock or ground elevation.
57) End effector
An attachment, such as grippers, spraying nozzles, welding tooling, and measuring devices, connected to the mechanical portion of a manipulator, balancers, positioner, or robot. Generally designed to fit a certain need and or lifting situation but is not restricted to single task.
58) Coil grab
Lifting devices, generally attached to a hoist or lift truck, which attach to a coil's OD via tongs or gripping mechanisms and enable the coil to be lifted without damage to the material. May also be configured to "turn" the coil over or move it in directions other than vertical.
59) Tong grab
A lifting attachment usually used in conjunction with a hoist or forklift that utilizes a "scissors" action to grip a load for vertical lifting or transport.
60) Drum turner
An attachment to a fork truck, lift table or below-the-hook on a hoist that enables that piece of equipment to turn over drums for filling and emptying.
