Winch Line Pull Calculator
Pull to drag or winch a load up a slope, with rolling/sliding friction.
A 'two-tonne' vehicle stuck in mud on a slope can demand its full weight in line pull — why recovery winches are rated at 2–3× vehicle weight and snatch blocks exist.
Formula
Winch Line Pull Calculator is a free winch pull for mechanical and machine-design engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Winch Line Pull Calculator
Pull to drag or winch a load up a slope, with rolling/sliding friction. The calculation implements P = W(sinθ + µcosθ) (Recovery/rigging practice; statics). A 'two-tonne' vehicle stuck in mud on a slope can demand its full weight in line pull — why recovery winches are rated at 2–3× vehicle weight and snatch blocks exist.

Frequently asked questions
What formula does the Winch Line Pull Calculator use?+
It computes P = W(sinθ + µcosθ), per Recovery/rigging practice; statics. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
A 'two-tonne' vehicle stuck in mud on a slope can demand its full weight in line pull — why recovery winches are rated at 2–3× vehicle weight and snatch blocks exist.
Is this suitable for machine design coursework?+
Yes — these are the exact Shigley/Machinery's-Handbook formulas, with the substitution shown step by step, so you can follow the worked example into your own calculation sheet.
Is the Winch Line Pull Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
