Inch Pound Equation - Example


 
Step 2: 
Once you have determined the maximum Inch Pound capacity of the truck, you must now determine a new lift capacity for the truck using a Load Center of 36" instead of 24". Again, you need the equation (A + B) x C = Inch Pound, where A = 18", B = 36", C = ? lbs. and Inch Pounds = 210,000

( 18" + 36" ) x ? lbs. = 210,000 I.P.
(54") x ? lbs. = 210,000 I.P.

To determine the new capacity, you must divide 210,000 Inch Pounds by 54".

? lbs. = 210,000 Inch Pounds / 54"

The new lift capacity of the truck is 3,888 lbs.
