Before
component selection is made, the following information must
be known. The following is a step-by-step process of assessing
your storage rack needs.
1.
ASSESS YOUR
STORAGE AREA.
| |
A.
|
Determine
open floor area available.
|
| |
B. |
Make
sure you include location of columns, doors and other
obstructions. |
| |
C. |
Check
overhead clearances for ceiling lights, girders, ductwork,
sprinklers, etc. |
| |
D. |
Check
condition and levelness of floor. |
| |
E. |
You
may want to supply a blueprint of ancipated travel patterns
and material flow requirements. |
| |
|
|
2.
DETERMINE LOAD
CRITERIA.
| |
A.
|
Pallet
type (4-way, Skid, Wing); Pallet size (Width, Depth,
Height); Load weight.
|
| |
B. |
Load
type, size and weight. |
| |
C. |
Will
there be single or multiple stacking of pallets? |
| |
D. |
Stability
of load on the pallet. |
| |
|
|
|

3.
LOADING AND UNLOADING
OPERATION.
A.
Lift truck characteristics.
- Turn
radius and depth of the pallet; add 12" for manuveuring
clearance.
- Reach length
- Lift height.
- Operator training.
- Lift capacity.
BEAM
SELECTION
DETERMINE
LENGTH.
Take
the width of the pallet or the width of the load (whichever
is greater) and multiply by number of loads per beam level.
Add 4" clearance between upright frame and load, and
between each load. For a straddle-type forklift, check clearance
requirements.
DETERMINE
CAPACITY.
Take
the number of loads per shelf and multiply by the load weight.
This total allows you to select the required beam from beam
capacity tables.
