In order to calculate the optimal Ramp length for your requirements, you can use this simple formula.
(Trailer Height divide by Gradient) multiply by 100 = Length of Ramp required
You need to first measure the height of the trailer or deck you wish to load onto / off.
The maximum gradient we recommend you use for the ramp is 30 degrees.
Trailer height = 1.2 metres and gradient = 30 Degrees
(1.2 divide 30) x 100 = (0.04) x 100 = 4 Metres
Deckheight = 0.9 metres and gradient = 28 Degrees
(0.9 divide 28) x 100 = (0.03) x 100 = 3 Metres
