Truck upgrades
T
he major markets for articulated dump trucks (ADTs)
are Europe and North America, where new engine
exhaust emissions are coming into force. This year at
Intermat many manufacturers will show their Stage IV/Tier 4
Final machines for the first time, and some already have such
machines available.
Although it is a fairly niche product, manufacturers say it is
a competitive market, and many are using the new laws as an
opportunity to redesign machines and
add new features. A common trend is for
payloads and capacities to be increased.
Julien Balardelle, product specialist at
Caterpillar, said the ADT market had
been particularly competitive in recent
years. He explained that maintaining
the pace of product designs to meet
customers’ requirements has been of key
importance.
He said, “The market is doing pretty
well as far asADTs are concerned, though
some regions aredoingbetter thanothers.
One areaof consistent growthhas been in
the US, where the economy is good and
we’ve sent a lot ofmachines there and the
order book is healthy. But there are places
