Loading surface height from ground:
Desired ramp length:
What to do with this information:
For a quick answer use the calculator provided on the left.
L = Ramp length
H = Loading surface ground height
C = Ramp inclination
Before driving onto the ramp or ramps, please make sure the bottom ends are parallel with the ground, as depicted in the drawing on the left. When deciding what the length of your ramp should be, make sure the ground angle is never over 16.5° - when converting this to a gradient, we get:
C = 30%
Let's suppose our loading surface is at a height of 1.0 meters from the ground, therefore H = 1000 mm. Keeping in mind that the maximum allowed value for C = 30%, we can determine our ramp length with the formula:
Our ramp inclination must not exceed 16.5°, but it can alway be less. We can always use a longer ramp, we will just have a more gradual incline. In the catalog, standard model lengths are listed in 500 mm increments. In the case of our example the nearest suitable ramp is: 3500 mm long.
All that's left now is to look at all the models with a 3500 mm length and pick the one with enough carrying capacity for our vehicle wheelbase.
