Cantilever Racking

General Product Information:

Cantilever Racks are ideal for storing long, rigid materials such as lumber, pipe and bar stock. The racks can be front-loaded by hand or with a fork truck or can be used as side pick racks in space-conscious areas. This guide will help you through the ordering process by providing basic information needed to select cantilever racks.

 

How to Order:

Cantilever rack is configured per bay and consists of three general components: Columns, arms and brace sets.

1. Determine storage needs by taking into account the length, depth, height and weight of the products being stored.

2. Arms: Choose arm style and length, along with the capacity needed to support the load. Two arms (one on each side) create a "level". Divide the weight of the load per level by two (for one bay) to give the individual arm capacity needed. (This assumes that the load is supported sufficiently by two arms to prevent load deflection).

3. Columns: Determine the number of arms needed per column side and vertical space required. Adding up all the individual arm capacities and vertical space required will determine the height and combined weight capacity needed for the two columns.

4. Brace: Determine brace set width. Take into account the length of the pieces planned to be stored. Brace set widths will provide center-to-center measurements of the arms installed on columns. One brace set per bay is required.

 

Tips on Column Spacing:

Column spacing is determined by the amount of load deflection (sag or bowing) between the arms. For fairly rigid stock, use half the length of the load. The overhang of the load at each end should be equal to half the distance of the column spacing. For less rigid loads, use one third the length of the load. Example: a rigid piece of stock that is 12' long, supported on two arms, would have a column spacing of 6' with 3' overhang. A more flexible piece of stock might require three arms for support with a 4' columns spacing and a 2' overhang.

Example:

1. Product to store: Pipes bundled at 8' long, 10" deep, weighing 2000 lbs.

2. Arm choice: 12"L, straight, with lip. Load weight is 2000 lbs. Divide weight by two (one level) to obtain 1000 lbs. per arm requirement.

3. Column choice: Assuming four levels of load are required, then eight arms would be needed with vertical spacing of 18" apart. Eight arms x 1000 lbs. capacity per arm = 8000 lbs. Combined required column capacity (4000 lbs. per column, single sided) at 8' high would be needed.

4. Brace: 8'L load with two-arm (one bay) support would require a 4' wide brace set.
