Right angle stack calculations (normal load)
Aisle width; use narrowest aisle in which truck must right angle stack products. See illustration on page 39 and
formula below
Truck specs and
load solve for this
number from
formula A-1 or A-2

Right angle stack formulas (normal load)
Right angle stack Formula A-1
When D is less than C + 2R
Aisle width = Z + A + B + operator clearance
Required aisle width for truck specs + load =
Z_______ + A ________ + B_________ =________

CAUTION
The pivot point of a three wheel truck is found
between the drive wheels and not outside the
turning wheel as it is with a four wheel truck.
Therefore, when calculating right angle stack for a
three wheel truck, use these formulas.
When Z is greater than D Then aisle width = Z + Y

When Z is smaller than D Then aisle width = D + Y

Y = (A + B) 2 + D

Mathematical calculation of right angle stacking aisle
Right angle stack Formula A-2
When D is greater than C + 2R, but less than 2Z – C – 2R
Aisle width = Z + Y + operator clearance, then solve for Y
Y = D - C - R 2 + (A + B) 2

Note:
* Y cannot exceed Z
* If Y is longer than Z, use wide load calculation (page 40)
Required aisle width for truck specs + load =__________
Z_________+ Y _________ = _________
