Incidentally, on the yellow truck at the top, the site says this was not photoshopped, but I think they are mistken. There appear to be no rear axles on the front two trailers. I may be wrong of course.
A 'tractor' can pull a trailer and pull one other trailer behind this. However on British roads this makes little sense as the towns and cities are too narrow for such vehicles. These are OK on trunk routes. I did see a French one trapped attempting to turn a corner (alongside parked cars) in an industrial estate years ago. he may still be there!
Maybe the front two trailers are special shorter ones that don't need back wheels because they're hooked on to the trailer behind. How's that for a fully technical analysis? :)
You're quite right, not only impractical in britain, but forbidden under our traffic laws. As Adullamite says, our roads are generally too narrow and twisty for really long trucks. Also we have a 44 ton limit for most trucks. Its possible to move bigger trucks and loads, but special regulations apply, routes may have to be pre-approved by highways and police authorities for particularly large loads, (such as bridge-sections, large opencast mine trucks and excavators, prefabricated sections of oil refineries, ship sections, high-voltage transformers, hydro-electric turbine parts, etc).
Your DHL truck has its fifth-wheel mountings above the axle sets on the first two units, so the rear ends of the first two sections are some distance behind the fronts of the cargo boxes of the following trailers.
"In the United Kingdom in 2009, a two year desk study of Longer Heavier Vehicles (LHVs) including options up to 11-axle, 34-meter (111.5 ft) long, 82-tonne (81 LT; 90 ST) combinations, ruled out all road train type vehicles for the foreseeable future." The scandinavian countries use them, and some european countries are experimenting with them.
So, if I understand you correctly, this is not done in Britain?
Triple fight in Nevada.

ReplyDeleteThe DHL truck picture was supposedly taken in New Zealand. Which makes sense. The triple in the above link was taken in Nevada.

ReplyDeleteHas no one ever considered tearing down some of those smaller towns and widening the roads? You guys care 'way too much about history. :) :) :)
ReplyDeleteA. - That's amazing logic. And you are probably right! I will never argue boat slopes with you again. :)
ReplyDeleteSome of them also have wheel dollies with 5th wheels, so as to act as add-on semi-trailers. I don't think that's going on in this picture, though.
Isn't this interesting????? I'm all a-quiver. I do so love big toys!
