1. Determine the number and spacing of support arms.
1a. Use enough arms under a load to prevent
deflection of the load. Deflection causes
undesirable side pressure on the arms.
Using wood blocks on the floor under the load,
test your load for deflection on a two-support system.
1b.If you do not detect any deflection,you may use two support arms.The arm capacity required will be half the load weight, and the upright centerline will be 1/2 of the load length.
1c.If you notice deflection with two supports,
try three supports.If this system works,arm
capacity will be 1/3 of the load weight,and the
upright centerlines will be 1/3 of load length.
If three supports are stil not enough,add
supports as necessary until deflection
is eliminated.
2. Determine arm length.Arm length should equal load depth.
3.Determine upright height.
Start with base height:
+ number of storage levels x load height
+handling clearance [4″to 6″]xnumber of levels
+number of arm levels x arm thickness
=upright height.
Note: Contact Stee/ King forcurrent arm and base dimensions.
Note:Check limitations at your plant such as ceiling clearance or fork lift height.
Note:Top arm leve/ must be below the top of the column.
4. Determine capacities required.
- Arms:Load weight÷number of arms per level=arm capacity.(Assuming each arm supports an equal amount of the load)
- Uprights:Number of arms per side x load per arm.
5.“Bracing lengths”refer to the horizontal centerline distance from column to column,as in the diagram. See Step 1 for the proper number of braces per type of load.
