How to Use This Calculator
- Enter the winch radius in meters (m). This is the distance from the winch's axis of rotation to its outer edge.
- Enter the load weight in kilograms (kg). This is the weight you plan to lift or move.
- Enter the pull angle in degrees. This is the angle between the load cable and the horizontal plane when the winch is operating.
- Click the "Calculate" button to compute the torque.
Understanding the Results
The calculator provides two key results:
- Calculated Torque: The rotational force the winch must generate to lift the specified load at the given angle.
- Torque per kg: The torque required per kilogram of load, helping to compare different scenarios.
Important Considerations
When using this calculator:
- The calculated torque represents the theoretical requirement. Always select a winch with a higher torque capacity than calculated to account for friction, efficiency losses, and safety factors.
- The pull angle significantly affects the required torque. A lower angle increases the torque needed.
- This calculator assumes ideal conditions. Real-world applications may require additional safety factors.
- For dynamic loads or complex operations, consult winch manufacturer specifications or engineering guidelines.
Principle Explanation
The torque required to lift a load with a winch can be calculated using the formula:
Torque (T) = Load Weight (W) × Winch Radius (r) × sin(θ)
Where:
T = Torque (Newtons·meters)
W = Load Weight (kilograms)
r = Winch Radius (meters)
θ = Pull Angle (in radians)
