Tri-axle half pipe tipper trailer

[ricm]

OK, so it's more than twin axle but it is for on-road use so have put this thread here instead of under the 'Construction Equipment' section.

The fabricated Aluminium body for my next project arrived from in Canada earlier this week, built to my specs by RCP57 who mostly builds tipper bodies to fit the standard King Hauler chassis:







1st class quality fabrication, really happy with it.

FYI, the pics above were taken before RCP57 put it in the mail to me - so don't ask me about the things in the background!

This is going to be a bit of a slow build, but will update as I make progress.

Chassis will be based on the Tamiya container trailer, with the whole axle group moved forwards by 1 axle spacing. Plan is to build in motorised support legs and everything fully wireless, with a screw drive mechanism for tipping using a 540 motor and 100:1 gear reduction which -should- be able to shift almost anything. I need this thing to cope with a full load of sand, otherwise what's the point....! All electronics have already puchased and/ or designed, built and tested.....

Got the chassis rails back from the machine shop. As usual, first class job. Both sides drilled with a few extra holes for the new axle locations

one side built here, showing custom chassis cross members to allow all the extra bits to be fitted. Black box at the back is the receiver board for the wireless control

decided to ditch the lower swing arms on the original suspension, they do nothing more than restrict axle movement





Adding the motor, gearbox and tipping drive screw



Other side rail....core chassis complete





So it'll look something like this but still loads to go.....
