Tri-axle half pipe tipper trailer

[Lmackattack]

I like that screw drive. looks well made. wish I had seen this before I used a ace hardware threaded rod in my end dump.

I also used tecnobotsonline for a reduction unit on my 1/4 frame. I went with a 50:1 and it lifts a full box of wet sand in about 20 seconds. power comes from a 7 cell battery. You can hear the motor is working to get the box moving but once its a few degrees off the tractor its smooth sailing. your 100:1 should be just fine for the task.


Keep the pics coming!

Hey Ric, it's great to finally see what I was building the tub for! I hope everything I did works out as planned. It looks like a great setup you have created and I can't wait to see the finished product.

Thanks again for allowing me to be part of it!

no worries Reg - I've shown the tub to a few folk here in Aus and they've been quite impressed....I'll see if I can convert a few for you

So I said this would be a slow build, but I got some more done over last few weeks...

rear end with hinge and bumper brackets



rear under-run bar



light lenses missing but otherwise mostly done






Underside view of the sub-frame for the main body, got the control for the tailgate hooks underway. The push/ pull rod will be activated by a part of the tipping mechanism

[ricm]

since trailer will be wireless control, it needs its own power supply....so got the battery box mounted for the 7.2V pack. Decided to use this size to make sure the screw drive has plenty of punch....



Also making side cabinets to hide the battery pack and also house the batteries for the support legs and one side and on the other side the H-bridge relays for the screw drive with manual over-ride switch

[ricm]

finally got some meaningful progress, still won't be finished before Christmas though...

tipping mechanism finished and mechanically tested - over 50 degree dump angle. Haven't done a weight test yet but the mechanism worked fine using a battery that didn't even have enough juice left for a truck with MFU....
