Carryfast, much like the other thread where I asked what real world experience you had of that particular subject you were trying to he authoritative on but got zero answer… I believe it was also about rear steer, maybe overhang with the van?Anyway the question is still open and applies here also… how many of these vehicles have you pulled? It wasn’t “flaming” from me… I was just pointing out that I’ve driven them for years in many scenarios and experienced none of what you say so I was just seeing where your experience in the subject was gained bit got bo answer? Obviously now I know you read it also so it’s another chance to answer…
By definition if I didn’t understand the difference between everything behind a fixed axle or axles = overhang and as some call it ‘tail swing’ ( sweep ) around that resulting fulcrum point them I’d be a danger on the road pulling a 45 ft Tri axle.Let alone tandem axle without the relative brake on that swing/ sweep provided by the fixed rear axle of the Tri.
The type of ‘rear steer’ being described here just means an axle which supports and tracks that same overhang and resulting tail sweep around the fixed axles ahead of it.In the case of the daft extended trailer design that’s a dangerous amount of it.
That danger is magnified if we’ve got drivers who don’t understand that difference.
In them thinking that rear steer is all the same and means the same thing, as having an actually even longer trailer but with less or negligible overhang but all trailer axles counter steer to cancel out the resulting increased cut in.
A decent grounding in truck building combined with knowing that a 45ft tandem axle UK spec trailer has more than enough tail sweep to handle actually helps in that regard.
It’s unbelievable that I’m getting flak for trying to help drivers understand a critical safety issue.Politely described as a gross exaggeration. Only in your mind Carryfast, could a failed, incomplete apprenticeship be described as a “decent grounding”, in technology that didn’t exist at the time of that failure.
Enough of a grounding to know that a rear steer axle behind the fixed axles of an extended overhang trailer ain’t there to make the slightest/any difference to the resulting massive tail sweep/swing.
Gave up to take up the better offer of works test driver passed with credit up to that point isn’t a ‘failure’ in my book.
