REGULATIONS
CHANGES IN GERMANY FOR 2-AXLE SEMI-TRAILERS
PENDLE AXLES IN THE NETHERLANDS
WITH PENDLE AXLES
The Dutch regulations also distinguish two kinds of axles: beam axles
and pendle axles. All types of axles with independent suspension are
currently classified as beam axles. In spite of several requests to increase
the axle weight, independent suspension with a long-term 100-tonnes
exemption will not be granted more than 10 tonnes per axle. Within
the same exemption regulations it is stipulated that pendle axles have a
maximum load capacity of 12 tonnes per axle. For 2-axle low-loaders
with independent suspension the difference is even greater, because
in combination with a 3-axle tractor the total weight stays under 50
tonnes. And therefore does not qualify for an exemption for the weight.
The result: 9 tonnes per axle for a 2-axle semi-trailer with independent
suspension and 12 tonnes for a semi-trailer with pendle axles. In
practice this means the 2-axle low-loader with pendle axles, such as the
Nooteboom EURO-PX, has 6 tonnes more load capacity than a similar
low-loader with independent suspension, such as the SL, Panther, MPA
and Twinaxle-2.
Within the German regulations two different kinds of axles are specified:
beam axles and split axles. Pendle axles as well as axles with independent suspension are classified as split axles. This year the Ministry of
Transport has decided to no longer issue exemptions for 12 tonnes per
axle when it concerns a 2-axle semi-trailer. Only if the semi-trailer is
equipped with pendle axles an exemption for 12 tonnes will be granted.
The German BSK (Federation of Heavy Transport and Crane Operators)
has asked the Ministry of Transport to align the 2-axle low-loaders with
independent suspension along with those equipped with pendle axles,
as is currently the case with semi-trailers that have more than 3 axles. As
a result of this request by the BSK, the Ministry of Transport of BadenWürttemberg has made two important decisions.
In the Netherlands the difference
between pendle axles and
independent suspension can
be as much as 3 tonnes/axle
The first decision stipulates that the BASt (Federal Highway Research
Institute) is given the task of comparing the difference between the
weight transmitted to the road when using split axles with independent
suspension to the weight when using pendle axles. In the other decision
it is laid down that throughout Germany – pending the results of the
investigation – 2-axle semi-trailers with pendle axles will be granted
exemption for 12 tonnes per axle and 2-axle low-loaders with independent suspension will be granted only 10 tonnes per axle.
FRANCE: IN CAT 3 MORE LOAD CAPACITY ON A PENDLE AXLE
French legislation divides abnormal transport into three categories.
The law distinguishes three kinds of axles: beam axles, split axles and
pendle axles. To determine the maximum gross weight, beam axles
and split axles (with independent suspension) are treated the same. An
exception is made for pendle axles. In Category 3 they may be allowed
higher axle weights than beam axles and axles with independent suspension. This depends on the number of axle lines, the distance between the
axles and whether single or double mounted tyres are fitted. Vehicles fall
under Category 3 as soon as the laden vehicle is longer than 25 metres,
wider than 4 metres or has a total weight of more than 72t.
The Nooteboom EURO-PX low-loader is the result of technical development over many years. The higher load capacity that is now permitted
in Germany for the 2-axle Nooteboom Euro-PX shows that innovation
has practical benefits too. Three important European countries – the
Netherlands, Germany and France – recognise the advantages of pendle
axles over independent suspension. The result: up to 3 tonnes more load
capacity per axle line. ■
