7 INSTALLATION SPECIFICATIONS AND GUIDELINES
7.1 INSTALLATION DIMENSIONS

The order forms provide you with the critical installation dimensions for the various types of ramps and platform depths. See 7.4
from page 14 onwards.

Compare the maximum installation parameters indicated in the order forms with the actual vehicle dimensions. If the actual
dimensions go outside of the maximum installation parameters, DON’T continue and contact your national DHOLLANDIA
distributor for further advice.
7.2 PLATFORM DEPTH AND VEHICLE FLOOR HEIGHT

The DH-AI*series ramps can be installed on a wide range of minibuses, vans and other light-duty commercial vehicles. vehicles
such as vans, minivans, etc.

Determine the ramp angle in function of the platform depth and the vehicle floor height. Perform a risk analysis in function of
the expected use; the loads, their weight and means of propulsion; and the maximum ramp angle acceptable for the end user.
Make sure that the embarkation and disembarkation of wheelchair occupants or the loading and unloading of cargo can be
done with an acceptable level of safety.

A maximum slope of 25% for passenger use and 30% for commercial use is recommended. Reference values for the various
platform depths are given in 7.4 from page 14 onwards.

When the wheelchair occupant does not have assistance from trained staff, the slope should not exceed 12%.

Useful formulas (approximation):
To calculate the minimum platform depth pd if the vehicle floor height vfh and the maximum ramp angle a are known:
Platform depth pd (mm) = vehicle floor height vfh (mm) / access angle (%) * 100
To calculate the ramp angle a if the vehicle floor height vfh and the platform depth pd are known:
Access angle (%) = vehicle floor height vfh (mm) / platform depth pd (mm) * 100
