Dec 31, 2012 Rules and Formulas. Door Weight: (1) Divide the total spring(s) IPPT by the cable drum multiplier. (2) Multiply the spring IPPT by the number of turns, and then divide by the Hi Moment Arm. High Lift: Measure the distance from the top of the closed door to the bottom of the horizontal track. IPPT: Inch Pounds Per Turn.
The IPPT tells you the torque that the spring exerts for each turn that is put on the spring. A spring on a 7' garage door, for example, typically has 7.5 turns. The torque, then, is the force exerted by the garage door at a given distance from the center of the shaft, as this is the location on which the spring acts.
For example, on a seven foot high garage door a 34" spring comprised of.250 wire would grow eight coils when it is wound and stretched.
