2.2 Notes for the Vehicle Installation
2.2.1 Trailer Hitch Requirements
The Trailer Hitch should be approved for the FWD/HWD trailer max. permissible weight (see
“Trailer Specifications”).
The Dynatest FWD/HWD Trailer can be delivered with a coupler intended for a trailer hitch
ball diameter of either 50 mm (1-31/32”) OR (optionally) 2” (50.8mm).
WARNING!
Make sure that the trailer hitch ball matches the coupler!
The trailer frame will be parallel to the ground surface (so that the guide shaft for the drop
weight will be perpendicular to the ground), if the centre of the trailer hitch ball is kept in a
height of 480-500 mm (18-20”) from the road surface when loaded with some 100kg, see
figure on a following page.
WARNING!
Be careful when loading the towing vehicle. Do NOT put too much cargo in the rear of
the car, which will not only affect the tilt of the trailer frame but also driving stability of
the vehicle.
If the vehicle is heavy loaded with cargo and/or personnel when testing, then make sure that
the hitch ball is still in the correct height (480-500 mm) from the road surface with the
FWD/HWD trailer attached.
For further guidelines please consult the Owner’s Manual from the vehicle manufacturer.
