Pallet Racking Glossary

Pallet Rackl

Aisle Guide: A barrier used to direct or limit movement in an aisle.

Anchoring: Lagging or fastening methods, used to secure columns, beams and ties.

Base Plate: Pad used to support a column and transfer column load to floor or ground.

Beam Connection: Device used to fasten shelf beam to column, wall etc.

Bracing: Restrictive supports used to limit movement in racks, uprights, shelves etc.

Buckling: The failure or collapse of a column generally caused by an added force.

Decking: Solid or perforated material used on shelves, load beams, or walkways to support loads of variable sizes.

Deflection: Distortion of column beam, tie, ect.. caused by a load or force.

Impact: The striking of one object against another. A load striking a beam or rack member.

Industrial Steel Storage Rack: A series of steel supports or beams connected together to form an assembly used to store industrial goods or material.

Live Load: Load being moved in or out of a rack system. Pallet load as opposed to dead load or weight of actual rack members.

Pallet Clearance: Clearance or unused space at sides, rear, and above loaded pallet.

Plumbness: The closeness of an upright or column to being vertical.

Rack Beam: A horizontal load support member in a rack system.

Rack Column: A vertical load support member in a rack system. A post.

Retrieval Device: Any device or mechanism used to select and pick up stored material from a rack. May be a manually operated fork truck or a completely computer controlled mechanism.

Safety Factor: Extra capacity designed into a system to cover unusual or extra demands on the system.

Skid: Steel or wood, movable unit load.

Uniformly Distributed Load: A load, as on a shelf, or pair of load beams, supported by all, or nearly all of the shelf or beam supporting surfaces.

Upright Frame: The vertically supporting assembly in a rack system. Generally consisting of 2 or more columns tied together with bracing members.

Maintaining Racks for Safety

Rack System

Inspection Program: Inspection programs depend on the size and use of each rack system. Where racks are heavily used visual inspections should be made on a daily basis. Once a week or bi-weekly is acceptble for racks that are used less frequently. Any damage should be reported immediately.

Repair: In most cases buckled or severely bent rack components should be replaced. Moderate damage such as denting or slight skewing can be corrected by adding bracing or splices. 90% of rack damage occurs between the floor and first horizontal beam, most damage can be seen from floor level.

Rust Prevention and Painting: Rust prevention or touch up painting requirements depend on the application.  Any high moisture or cooler application calls for careful attention to paint conditions.

Tightening Lags and Connecting Bolts: Racks that are lagged at a time of installation should be tightened in accordance with torque data supplied by most manufacturers, and the same criteria must be used when tightening connecting bolts as the security of the entire system is dependent upon proper fastening methods. Random checking should be used to ensure there has been no loosening of lags or connections.

Cleanliness and Good Lighting: Cleanliness and proper lighting are keys to a well run warehousing operation. A well maintained and clean storage are are musts in any phase of the food industry and good housekeeping should be prevalent in all storage operations. Proper lighting facilitates rack entry and pallet placement and aids in reducing rack damage.

Pallet Rack History

Rack Systems

As recent as 1900 items and products were stored haphazardly on the floor or on top of other material. This was acceptable until space and time became more of an issue. Racks were developed to answer the need for more storage space. Engineers figured out that racks could store four times the amount of material in far less space.  Rack has come a long way since then and the height of rack structure is now only limited by the equipment used to store and retrieve the material.

While the terms shelving and rack are often used interchangeably there is a difference between the two. Racks are designed to store palletized, containerized or large unit loads typically placed by handling equipment such as fork trucks, stackers etc…

Industrial storage racks are classified into two basic types.

1. Stationary Racks
Selective Pallet Racks
Drive In and Drive Thru Racks
Stacker Racks
Cantilever Racks
Pallet Flow Racks
Package Flow Racks

2. Portable Racks
– Pallet Stacking Frames
– Unitized Portable Racks
– Special Purpose Racks

Cantilever Rack: A Quick Overview

Cantilever racks are great for storing steel bars, lumber, and pipe. Long, heavy items are stored with ease. The main benefit of a cantilever rack is increased accessibility to loads. Forklifts can easily load and unload from rack arms and base. Another benefit of cantilever rack is that it is easy to add additional arms, uprights or braces as storage needs change. For more information on a cantilever rack system call Material Flow at 1-800-338-1382 for expert assistance. There are three main parts to a cantilever rack system.
