|Step 1. Length of Beam|
|Select which type of lift truck you will be using.|
Counter Balanced Truck
Straddle or Outrigger
For Counter Balanced
Maximum width of pallet or load (whichever is larger) __________
Number of loads across (between upright frames)_______________
Allow 3″ between upright frame and loads.
Allow 4″ between loads
Example: Allow 10″ for two across storage.
Total length of beams (Max load width plus allowance)
The clear distance between posts will be beam lengths plus space between plate and columns.
For Outrigger or Straddle
Inside Clearance between outriggers ____________X 2=_____________
Width of outriggers plus 3″__________ x 3=__________________
*Total Beam length ___________
*If load overhangs outriggers, add amount of overhang for each load.
This diagram shows the difference between wing and flush pallets.
|A) Depth of pallet or load
D) Total Height (load and pallet)
E) String Dimension
F) Total Weight (load plus pallet)
Step 2. Beam Capacity
Number of pallets____ X load weight = required capacity per pair____Beam capacity ___ lbs. for ___length = type____________
|The beam capacity chart represents the uniform distributed load to be carried by a pair of beams. For single level racks, decrease beam capacity by 15% to account for the reduced end fixity, and use only heavier beams, which have four hook end connectors.|
Step 3. Frame Depth and Spacers
|Frame depth A). should be 6″ less than pallet stringer dimension________________ (must be in 3″ increments)Row Spacers and Wall Fixes
Suggested row spacer length:Amount of pallet or load overhang___________ x 2 ___________
Add 6″ (suggested clearance)=_____row spacer length
Wall fix: pallet or load overhang:___________ + 6″__________ wall fix length__________
A: Depth (Stringer Length)
B: Width (Board Length)

Step 4. Frame Upright Height
|Starting at floor level:Add height of pallet and load (A)_________ (B) and (C) or use 9″Add clearance between top of load and bottom of beam (B)____________
Add thickness of support beam
Multiply total times the number of shelf levels
_________ to equal frame height
|Rack is required to go only as high as is necessary to support top pallets. Height may also be limited by the extent of fork elevation of lift truck. Provide a minimum of 6″between top load and ceiling obstructions. (Check local fire codes)|
|Step 5. Frame Capacity|
|Add total of loads supported by shelf beams___________Determine maximum vertical shelf spacing (x)__________________Determine number of levels per bay___
and bays per row___________
