INTRODUCTION PRELIMINAR STUDIES AND CONSIDERATIONS
MOUNTING AND CONSTRUCTION
For mechanical coupling devices unsuitable for transmitting vertical bearing
loads
So as not to exceed the maximum axle load, the correct location of the fifth wheel
F must be calculated:

WB
O - Reference point
Table 1-197 SPBTA22_005 Terms used in this calculation
Using the equations of static equilibrium:
See chapter A.2.1 "General concepts and formulas".
The value U can be obtained using the formula (11).
