Pedro Yes it is very interesting. The trailers in the pictures almost look like they would roll along any USA road. I dont have any pictures of USA trucks for posting but maybe you know what they look like. Tom in MN

When you say tonnes, am I correct in assuming you mean a metric ton which is 2200 poundsIJ Does the 50 tonne weight limit include the weight of the truck or just the grain it is haulingIJ In the US the gross weight of a semi-truck with two axles on the tractor and two axles on the trailer is 80,000 pounds. In western Kentucky, where I live, the coal trucks can legally run at 120,000 pounds gross weight and in eastern Kentucky they can legally run 160,000 pounds gross, but I am not sure if they have to have extra axles.

Ag Teacher, Yes, a metric tonne is equivalent to 2,200 pounds. The weights i mentioned were all the net payloads for the grain only. An empty road train would weigh about 29 tonne, giving a total gross weight of 79 tonne (174,000 pounds) Cheers

Here's a pic of a Canadian super B trailer. Gross 62.5MT, net 42MT on primary roads. 54.5MT gross on secondary road.

The steering wheels on the Aussie trucks would be on the wrong side here in the US.

camshaft, That pic of your Super B looks to me the same as what we call a B-Double in Australia, same gross weight too (62.5MT). Is that a belly dumperIJ Are they popular thereIJ Do you have any larger combinations on your roads, or is that the largestIJ Would be good to see some US combinations too. cheers pedro

When you think about dumping on the fly out of the combine; I think the Aussies have it right.

pedro, The super B grain trailers are all belly dump (hopper bottom). They are very popular, it's hard to compete with a smaller truck. The only larger combination would be the King B which is the same except for a tri axle on rear trailer. They are only allowed in Sask. and must be hooked up with GPS and auto tire inflation. When loaded they have to run lower tire pressure and lower speed. The DOT can then monitor which roads they are on and tire pressure they are operating at. Axle weights: Steer 5.5 MT Drives 17 Tandem Tri axle 23MT Rear 17 Tandem On a 6 axle rig (3 axle tractor - tri axle trailer) tri axle is allowed 24MT lift axles are not allowed in Western Canada. DOT thinks that truckers will operate with the lift axle in the up position and wreck roads.

Super-B end dumps are becoming more common in Ontario but for grain hauling its hard to beat Super-B belly dumps. The one big drawback with belly dumps being that you are limited to what you can haul. Here in Ontario is common for guys pulling Super-B dumps to haul grain into a terminal then shoot across town and load 20T steel coils into the trailers for a back haul, or scrap steel, sand , gravel etc. Dumps are much more versatile in that respect but for guys what are dedicated grain haulers Super-B bellies are the way to go.Personally speaking we run a 19ft tri-axle dump ( lift and two drives) pulling a 26ft 4axle dump ( tandem dolly and tandems on the trailer),which allows us to gross out at 140,000lbs , or a net of 41Mt
