How to determine the length of loading ramps
During use, the inclination (α) of loading ramps must not exceed a maximum slope of 30% (approx. 16.5°). In order to establish the minimum length (L) of loading ramps to a good approximation, apply the following formula:
Height difference (H) refers to the height of the loading bed from the ground .
EXAMPLE: Let's assume we need to overcome a height difference (H) of 1200 mm. By applying the formula indicated above,we obtain:
LENGTH OF LOADING RAMP IN MILLIMETRES (L) = 1200 mm x 100/30=4000 mm
The diagram clearly shows the dimensions used to determine the length of loading ramps and their interrelationships expressed by the formula above
