INTRODUCTION PRELIMINAR STUDIES AND CONSIDERATIONS
MOUNTING AND CONSTRUCTION
On the other hand, the maximum permissible loads on the coupling device must not
be exceeded. These loads depend on vehicle model and engine type. Therefore, if
the standard vehicle overhang has been extended, the maximum approved loads on
the coupling device will vary as a function of the dimension of the rear overhang.
The Body Builder should therefore foresee the decrease of the load capacity on
the trailer depending on the increase in rear overhang length. The requirements
specified in REGULATION (EU) 1230/2012 - MASSES & DIMENSIONS must be con-
sidered.
The Body Builder must check that the static load on the coupling device does not
exceed the permissible load on the rear axle and the minimum load on the front
axle.
If a coupling device is installed in the vehicle, it will be necessary to transfer the
lighting functions from the vehicle to the trailer. This requires connecting the trailer
to the vehicle, either directly by quick connectors, one for each lighting function, or
by connecting to the vehicle CAN bus network.
Semi-trailer
A semi-trailer is a trailer with one axle or group of axles, in which the union with
the tractor vehicle is performed through a set installed on the tractor vehicle chassis
(known as fifth wheel). In this case, the tractor supports much of the load and also
the semi-trailer weight.
To better ensure the functioning of the complete group, HMC advises using only
coupling devices (fifth wheels) supplied or approved by HMC.
The Body Builder must check whether the dimensions and permissible weights allow
an articulated vehicle to be built according to the vehicle model and the legislation.
- The calculation of the optimum position for installation of the fifth wheel is

determined by the value D, which represents the theoretical horizontal force
