1) Selective rack
Steel storage racks arranged in either single or back-to-back (double) rows. Each of the rows offers a bay or number of bays in the down aisle direction. Pallets are generally positioned side-by-side in the down-aisle direction at each level of the bay. The advantage to this configuration of rack is that all pallets are accessible from the facing aisle.
A storage surface located above the floor level and usually contained in shelving system or rack system.
The formed steel sheet which attaches horizontally to the posts and supports the load. Shelves are available in many sizes and a number of capacities.
Shelves should be specified based on the customer's requirements and uniform load capacity that the shelf must support. Steel gauge, shelf formation and reinforcing varies from manufacturer to manufacturer and thus determines shelf capacity.
3) Shelf depth
The horizontal distance measured between the outside faces of beams.
4) Shelf divider
A formed steel partition placed within the shelf opening to subdivide it into smaller compartments. Some types of dividers include: full height, angle, tapered, sliding, floating.
5) Shelf opening
The basic shelving compartment formed between two shelves within a unit of shelving.
6) Shelf reinforcement
A variety of flat bars, angles, channels or other formed sections which are placed within or under the shelf to reinforce the shelf and prevent damage due to shock loading.
7) Shelving post system
The vertical upright member that supports the horizontal shelf. Posts are manufactured in a variety of configurations.
8) 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.
9) Single deep rack
The simplest of all racking systems. This rack is selective and accommodates only a single pallet.
10) Single deep selective rack
Rack structure which allows loads to be stored one unit deep on either side of an aisle.
11) Slave pallet
A pallet used in an automated rack system.
12) Small parts storage
The system of storing small parts/items usually utilizing bin shelving and rack and storing the parts in plastic or metal bins and containers. Carousels can be used for storing and retrieving these smaller parts.
13) Stack only container
A container that possesses self-supporting and straight walls. This feature means that the container walls are straight and can support the total weight of several stacked containers. Stackability reduces the required floor or rack storage space for empty containers.
14) Step beam
A beam that provides two horizontal surfaces on which the rack decking can be placed. Usually the top surface supports the deck and the lower surface supports the reinforcing members.
15) Storage aisle
An access route to storage areas such as rack bays, slots for pallets, bins or containers.
