Enter the output torque and the distance from the center axis that the winch pulls at into the calculator to determine the winch force.

Winch Line Pull Force Formula

The following equation is used to calculate the .

WF = T/X

  • Where WF is the winch force (N)
  • T is the torque output (N-m)
  • X is the distance from the center axis the winch acts at (m)

To calculate the winch force, divide the output torque by the distance to the center axis.

What is a Winch Force?


Winch force is a term used to describe the amount of force a winch can exert.

A winch machine is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the “tension” of a rope or wire rope (also called “cable” or “wire cable”). It consists of a spool and an attached hand crank in its simplest form.

How to Calculate Winch Line Pull Force?

Example Problem:

The following example outlines the steps and information needed to calculate winch force.

First, determine the torque exerted by the winch. For this problem, the torque is measured to be 450 N-m.

Next, determine the distance from the center axis the winch acts on. In this case, the distance is measured to be 2 m.

Finally, calculate the winch force using the formula above:

WF = T/X

WF = 450/2

WF = 225 N
