I have often wondered why no one has developed a multi-wheel steering truck trailer. I know nothing about the engineering difficulties, or the cost penalty, but it seems to me that multi-wheel steering would make a truck, even a long truck, much more manouverable in confined spaces.
- frederikvs 4y agoPerhaps it makes more sense to have a few big vans over one big truck, when it comes to manoeuvrability in small spaces. A big van is more manoeuvrable than a full-sized truck can ever be, even with multi-wheel steering - you still have a honking big box that can't bend.
- rhn_mk1 4y agoTo my surprise, they actually exist. Sadly, I'm only relying on testimony, so have no way to prove it.
- Gordonjcp 4y agoMost artic trailers with more than two axles (and many with only two axles) have got multiple steer axles.
- rascul 4y agoThis is a thing on some large fire trucks. At least for this application it requires someone steering from the back of the trailer. See this one in Seattle for an example. https://www.youtube.com/watch?v=fhuSwHni0jc https://www.youtube.com/watch?v=fhuSwHni0jc
- leoedin 4y agoThis is super-common in Europe. You see a lot of trucks around London with rear wheel steering. eg http://www.transportengineer.org.uk/transport-engineer-features/march-of-the-large-rigid/141645 http://www.transportengineer.org.uk/transport-engineer-featu... http://spectrumfreight.co.uk/view_news.php?cid=15 http://spectrumfreight.co.uk/view_news.php?cid=15
