Horsepower (HP)
Common unit of mechanical power, one HP is the rate of work required to raise 33,000 pounds one foot in one minute.



Formula to calculate how much capacity/ pull you need per rail car !

One Imperial Horsepower Equals
• 33,000 foot pounds per minute.
• 36 inch pounds torque at 1750 RPM.
• .746 Kilowatts.
• 1.014 Metric Horsepower. (PS)
• 42.4 BTU per Minute.

Torque (T)
Torque is a twisting force. Torque causes rotation of a shaft, or it will set up a twist in a stationary shaft. It is generally expressed in foot pounds or in inch pounds. Torque is measured by the load or pull and by the distance of the pull from the center of a shaft.

Calculation Examples
A cable wrapped around a 6″ dia. drum must lift a 2500 pound weight. The drum rotates at 30 RPM.
