The last fifteen years five-axle rigid vehicles are very popular in the
Netherlands. Since we have Terberg and GINAF trucks, the heaviest ones has
always 5-axles. In the Netherlands is it common to have a five-axle vehicle
with a gross weight of 50 tons. Some specials (because of the special axle
distances) can have a technical gross weight of 56 tons! Four-axle rigids
are allowed to have a gross weight of 46 tons, also, of course that depends
on the
axles distances. For example a normal MB Actros 8x8 has a 37 tons chassis.
The 8x8 GINAF and Terberg has a 42 tons chassis, but some specials, which a
very popular nowadays, has 46 tons chassis! A five-axles Actros rigid is
typed as a 47 tonnes chassis. GINAF can build a 53 tons chassis!
But there a tendens that tractor/trailer trucks has six axles. That's mainly
because of the axle presure when the truck isn't 100% loaded. An example: a
5-axle tractor + trailer is loaded with 30 tons concrete bricks. The driver
unloads 15 tons from the back. Now the drive axle of the tractor has a
presure of about lets say 13 tons. The authority say that's too high. That's
why more and more tractors are 6x2s. These vehicles are also used by the
England drivers!

I don't have well experiences with the geared version. I already
'demolished' three of them. I only use them for light purposes, like slewing
a loading crane behind a truck. Because my models are very big, I need
strong motors. The geared 9V motor isn't strong enough! But I still prefer
the good old 12V ones, the ones which were used in the blue railed trains.
Most of the eight 12V motors I have are nearly thirty years old, but they're
still working!
