The solution is more axels. Haven’t you seen cement trucks with the deployable 3rd axel? And the weight limit is 160,000. You forgot the 2nd trailer

- Someone 4y agoI don’t know what it costs, but adding an axle doesn’t come for free. If it did, those axles would always be on the ground. So-called “lift axles” can be raised because keeping multiple sets of wheels on the ground makes cornering harder, increasing tyre wear and energy usage.
- ProfessorLayton 4y agoEven so, diesel with a 2nd trailer >> electric with a 2nd trailer, which changes the economics in a non-trivial way. There's also the question about how to pay for road wear, which is currently subsidised by consumer vehicles, as the diesel tax falls far short of paying for itself, while there's no tax infrastructure for electric yet — that will also impact the economics of this. I'm a full proponent of electric vehicles, but full electric doesn't seem quite ready for semis. Perhaps hybrid is the way to go vs full electric, at least until the battery tech catches up.
