TRACTOR FOR SEMI-TRAILER
Fifth wheel
▶
The fifth wheel and the chassis fastening plate are safety devices and must be type-approved;
therefore, modifications to their structure is not permitted.
For installation of the aforementioned units, pay careful attention to the indications supplied by the Manufacturer.
Fifth wheel position
The position of the fifth wheel depends only on the load/maximum permitted mass on each axle for any axle configuration.
Always check that:
●
the maximum permitted loads are not exceeded on each axle or axle assembly for any specific position of the fifth wheel
and for the loads applied to it. If the original kerb weight indicated on the Certificate of Conformity changes due to outfit-
ting and/or the changes made, reference must be made to the actual kerb weight of the tractor and with all the equipment
(including fuel, tools, driver etc.);
●
the maximum permitted length for the combination is not exceeded for each and any position of the fifth wheel and for each
type of semi-trailer;
●
all the geometric conditions ensure safe coupling of the semi-trailer, in accordance with current Regulations, particularly if the
fifth wheel has been repositioned.
The position of the fifth wheel can be measured:
●
from the centre of the rear axle for tractors 4x2 (Figure 20) and 6x2C (Figure 21);
●
from the centre rear axles for tractors 6x2P (Figure 22);
●
from the centre of the tandem axle for tractors 6x4 (Figure 23).
To calculate the furthest forward/furthest retracted position of the fifth wheel and the maximum theoretical mass at full load
without exceeding the maximum permitted theoretical mass on the axles, the criteria indicated below can be used.
