T
he 4-axle trailer was supplied by
Knapen Trailers from The Netherlands
to Transportbedrijf A. Krol. Knapen
specialises in everything to do with mov-
ing-floor trailers and goes a lot further than
just standard trailers. With most suppliers,
Variant X or Model Y is the starting point.
At Knapen Trailers it is the customer’s re-
quirements that are the starting point. Only
then do they look at a vehicle and they do
not shy away from special construction.
The 4-axle trailer is a great example of
this. The requirements were clear: a solu-
tion for the transport of waste and compost
with the greatest possible loading capacity.
Another major requirement was that there
should be no fines for overloaded axles as
a result of poor weight distribution. People
often choose a 3-axle truck with a 3-axle
trailer. In order to use the additional axle
under the truck properly, the trailer has to
be loaded as much as possible at the front.
Krol choose a 2-axle truck with a 4-axle
trailer. The additional axle under the trailer
is financially more attractive because of the
longer service life. Moreover, the axles are
better distributed along the length of the
load. The fourth axle under the Krol trailer
is a steerable axle as well as a lift axle. The
4-axle trailer therefore steers forwards and
backwards like a 3-axle trailer. In addition,
the first axle is also designed as a lift axle.
Knapen Trailers has been supplying 4-axle
trailers to Scandinavia for years. As an ex-
tra option, Krol opted for a remote control
for the moving floor. From now on, this will
be a unique Knapen Trailers version that
can be used to control not only the moving
floor but also the lift axle and the lights.
