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.
77) Side loader truck
An industrial truck with lifting capabilities and able to accommodate the narrowest of aisles, depending upon the model and type, all the way down to the 5 foot range. Trucks operating in this range are sometimes called very narrow aisle (VNA) trucks. With the exception of the platform type sideloader, the fork and/or the entire mast on a VNA style truck is capable of rotating or swiveling 90 degrees left or right within the aisle from the down aisle orientation. Some manufacturers have models that can stack in storage racks 10-12 pallets high.
78) 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 .
A stationary (does not mean that nothing moves) movement assist device that is often equipped with end effectors for handling different types of loads. End effectors include all forms of grippers, forks, barrel grabs, etc. Manipulators counteract the weight of the load, rendering it almost weightless by way of hydraulic or pneumatic cylinders, or simply by way of counter weights and the exercising of very limited manual control. Most manipulators require manual actuation and control and are therefore manual assist devices. They are mounted to the floor, wall or ceiling. In some cases, manipulators are mounted to a fixed base plate and the entire unit can be moved via a trolley, cart or frok lift truck.
