For example, if a vehicle weighing 3,000kg is winched up an incline of 100% on a
marshy surface, the above formula would be used as follows:
Where Wt: 3,000kg, S: 0.52 G: 0.71
RPF = (Wt X S) + (Wt X G)
= (3,000kg X 0.52) + (3,000kg X 0.71)
= 1,560kg + 2,130kg
= 3,690kg of effect required to recover the vehicle.
Note: A gradient of 10% is a rise of one metre in ten metres (Height/Distance).
