Example:
A vehicle is stuck in sand in a slope with an inclination of 15°. The Vehicle weight is
10,000 kg.
RPF =
M (sinα + Rr) × (1 + Ff) g
1,000
=
10,000 (0.26 + 0.325) × (1 + 0.05) 10
1,000
= 61.4 kN
A pulling force of 61.4 kN (≈ 6.1 T) is required.
Winch basics
The required pulling force increases if the gradient increases.
