Racking Shelving

Cantleg Frame

Cantleg frames have posts set back 6” to 9”, sloped up to the first beam level.  This allows operators to have more maneuverable clearance at the floor pallet position.  The Cantleg is more durable and less impact damage prone than straight leg racking. Posts are usually reinforced for incremental load capacity.

Cart–Trak

Mini Plastic Rollers inside a steel track, usually 2 to 3 tracks per carton width x the number of cartons per bed (per shelf level). Ideal for small parts with light loads.

Carton Flow Rack

Case handling system designed to increase the number of picking faces in a fast moving handling zone.  Lanes are SKU dedicated. Carton Flow systems are also used for broken case handling of high demand SKU’s, with or without pick-to-light sourcing.  Typically used in a FIFO environment by placing inclined rollers in lanes 4’ to 8’ deep.  Also referred to as gravity flow or dynamic flow handling systems.   May be used as a standalone system, or incorporated into an existing pallet rack system.

Carton Roller Flow

Mini Conveyor Rollers in a steel track. Carton Flow roller width is equal to carton width x cartons per shelf bed. Ideal for large parts with heavy loads.

Carton Versa Flow

Staggered wheel tracks for varied carton sizes per bed with medium to heavy loads.

Clear Overhead/ Stacking Height (working head room) Sprinkler Clearance

The distance from the floor to a point usually at least 18” below the lowest overhead obstruction. The clearance required between the top of the highest load and the lowest overhead obstruction – varies by local fire codes.

Cross-Aisle Ties

The Cross Aisle Ties connect a single bay to a back-to-back bay, to prevent overturning of the single bay. Single rows that are 6 times higher than the depth of the frame, require special anchoring or extended frames to allow for cross aisle ties. Cross aisle ties are usually installed just below the ceiling trusses, to prevent impact from the pallet when loading the top bay position.

Dexion

A company / brand associated with the “Dexion” Slotted Angle steel strip construction system, widely used since the 1950’s for shelving and storage racking.

Double Posting

Doubling of the front and/or rear frame columns to a specific height, usually by welding one column behind the other to create a composite section.  The double posted frames double the load capacity up to the double posting height (usually the first beam level) and add extra durability against impact.

Double-Deep Racks

A racking layout with back-to-back rows of 2 deep selective racks.  Usually two rows of selective racks, one placed behind the other, on which pallets may be placed 2 deep by a double-deep reach truck. 50% of all loads are immediately accessible; accessing a back row pallet requires removal of the front pallet. Ideal for managing many pallets of few SKUs with pallets being stored and retrieved by an Automated Storage/Retrieval Machine (ASRS).

Double-Stacking

Pallet loads stacked one on top of another.

Drive-In Rack

A rack structure comprised primarily of vertical upright frames, horizontal support arms, and horizontal load rails, typically used for single width with multiple-depth storage. This structure includes an ‘anchor section’ with horizontal beams supporting the load rails. Loading and unloading within a bay must be done from the same aisle. 2-way Drive-In Racks combine back-to-back rows of drive-in racks into a single entity, with a common rear post.  This allows forklifts to enter the individual bays of the racking and delivers higher density storage with 80% less storage space.
