INTRODUCTION
PRELIMINAR STUDIES AND CONSIDERATIONS
MOUNTING AND CONSTRUCTION
The base plate is designed with a series of folds (ripples) that provide the height,
stiffness and strength necessary to withstand the loads produced by the fifth
wheel. These folds should be higher or lower depending on the load to be
distributed and on their number. Its design will permit loads to be uniformly distrib-
uted on the chassis frame or subframe. This reduces the forces transmitted by the
fifth wheel to the subframe.

The Body Builder is responsible for selecting the required size of the fifth wheel and
base plate. Fifth wheels must comply with national and international laws, and be
approved. It is recommended that the manufacturer's guidelines should be followed.
Regulation ECE R 55 and the standards in force in each country should be kept in
mind.
Type of connections
At least all the consoles available in the chassis from factory must be used. If
necessary more consoles can be added, but under no circumstances should fewer
attachment points be used than those incorporated in the chassis frame from fac-
tory.
In this type of vehicle, the use of flexible connections with a low degree of flexibility
(F_1) is recommended along the entire length of the chassis frame.
