6GETTING STARTED
Many vehicle manufacturers issue important instructions on various aspects of the ramp installation, specific to the brand and
type of chassis. Examples:
welding instructions or the prohibition to weld
instructions on chassis drilling and bolt-on connections to the chassis
recommendations on the use of mechanical or hydraulic stabilizing legs
NOTICE
ALWAYS verify and ensure compatibility between the ramp and the vehicle.
ALWAYS ensure compliance with the fitting and body building instructions issued by the vehicle manufacturer.
Make sure planned modifications to the vehicle chassis and body will not adversely affect the strength and integrity of the vehicle.
If the instructions of vehicle manufacturer conflict with the installation instructions issued by DHOLLANDIA, contact your national
DHOLLANDIA distributor for further advice. See contact info on page 3.
Verify if the installation kit is complete and that all parts needed to install the ramp, are present.
Compare the actual vehicle dimensions with the maximum installation parameters indicated in the technical documentation. If
the actual dimensions go outside of the maximum installation parameters, DON’T continue and contact your national
DHOLLANDIA distributor for further advice.
Verify and make sure that the vehicle chassis and body are strong enough to support the forces induced by the ramp at its
maximum rated capacity. Refer to the instructions of the vehicle manufacturer for calculation and construction guidelines.
Execute the required stability and weight distribution calculations.
Make sure that the body is accurately fitted to the vehicle chassis.
Remove all objects that impede the installation of the ramp (bumper bar, spare wheel carrier, etc.). If necessary, consult with
the vehicle manufacturer for replacement solutions (e.g. special spare wheel carriers, exhaust pipe modifications, etc.).
Finish the ramp in accordance with the road legislation of the country where the vehicle will be registered.
After installation, work through the checklist of the Pre-Delivery Inspection (PDI). Make sure the final inspection is signed off
by an inspector who is not part of the installation team.
During installation and testing, verify and make sure that the ramp and its moving parts don’t interfere with any of the vehicle
systems (e.g. the suspension, braking system, hydraulic and electrical circuits, etc.), or cause damage to them.

7INSTALLATION 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 aare 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
EXAMPLE

13
DHOLLANDIA
Where required, the relationship between % and ° ramp angles is as follows:
Percentage ramp angle
degrees
30%
16.7°
25%
14°
20%
11.3°
15%
8.5°
10%
5.7°
Check if the vehicle chassis and body are sufficiently strong to carry the proper weight of the ramp with its nominal load, both
statically and dynamically.
When unsure about the suitability of the vehicle, contact your DHOLLANDIA distributor.
Practical check: On technical drawings in paragraph 7.4, a bumper clearance curve is drawn. Use the dimensions on this
drawing to verify the suitability of your vehicle.
7.3 LATERAL INSTALLATIONS
When the ramp is located at the side door it is possible that it stands over a stepwell. A support must be created to fill the gap
between the base plate and the step.
This support needs to be level with the vehicle floor and sufficiently strong to sustain the forces induced by the load on the
platform.
