31) Full cantilevered jib crane

A form of wall mounted or column mounted jib crane that utilizes a vertical pivoted member and a bridge or mast that extends at right angles to the pivoting member.  This design adds the advantage of having the jib boom at the highest hook lift , thus taking advantage of an entire building height.

32) Work station crane

An overhead crane generally used for ergonomic purposes and consisting of bridge(s) and runways made from enclosed metal track.  End trucks attached to the bridge girder allow for ease of movement. The entire system is designed to allow workers to move loads by hand pushing the load with the assistance of a vertical lifting device such as a hoist or vacuum lifter.

33) 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.

34) 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 .

35) 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 .

36) AEM

A conveying system which consists of monorail track, track mounted electrification, individually powered vehicles, a supporting structure, a control system, lifts, switches and turntables.

37) Pallet

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.

38) 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.

39) 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.

40) 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.

41) 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.

42) 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.

43) Spreader beam

A below-the-hook lifting device that utilizes two or more hooks (attaching devices) located along a beam and the spreader beam attaches to the hoist by means of a bail.  The spreader beam is used to handle long or wide load and serves to "spread" the load over more than one lifting point. Often used in conjunction with slings.

44) Bottom block

The device at the bottom of a hoist's lifting medium (chain/wire rope) through which the medium is reeved and supports the hook and/or an attachment.  May be stationary or rotating depending upon the requirements for the piece of lifting equipment.

45) Pallet lifter

A below-the-hook lifting device that utilizes forks in its design and serves to take the role of forklift forks while utilizing the capabilities of a crane and/or hoist.  Generally, counterweighted at its top and attached via a bail and hook arrangement.
