Why do you want it telescopic.? If you want wider for stability what about some thing like stabilisers on a child's cycle that could fold up when on road
would it be ok then tomhave the tanker axles steered by tractor spool so the tanker could crab behind the tractorAssume so he can push it out so axles are running on virgin ground and reduce compaction. Was there not a video on here a while back of a self propelled tanker in holland that had a telescopic axel? Or did it just angle and crab to get the same effect?
Id be interested to how you do it as i could also do with on mine for stability, 3000g single axel hispec top heavy beast.
No worries it was only a suggestion. I've no experience with the challengers myself.I used to hire a 3000g challenger,I never rated it the running gear is something daft like £8.5k,and then all it wanted to do was go straight when cornering on the road.
Best set up locally is a 3000g with and air lift axle,far cheaper and works better than majors idea.
I'm sure I saw a 3 wheeler Horsch with an extra , telescopic , lifting axle , was in Profi maybe 10 years ago , think it was for drilling into an even bed . The Horsch company do a chaser bin which has an telescopic axle according to their website , more for stability .
