Tank Transporter

[menright]

The tank is complete so now for part 2, something to transport it. I also might need a bigger workshop as this thing is 3m long already and it is still not complete. I have put loads of video up on Youtube about building it plus loads will be added to the Blog. Did a quick drive test to day with the tank on the back and it pulls the 90kg tank no problem at all. I did have a few problems with the trailer wheels scrubbing a bit through tight turns, I guess that is why trailer steering was created.
I will have a look into trailer steering on the wheels and see how easy it will be to impliment. The small 300w motor seems to be powerful enough to haul all the weight but going over rough ground might present some problems so I might pop in a bigger motor. I also tested a cheap Chinese ESC rated at 640Amp's. Not sure how the company measures Amps but it not the way I do. I worked well but did get very hot so a bigger heat sunk and active cooling might be in order. There is still so much to complete but I love working at this scale.

Cool project. When you see those cheap Chinese ESCs with huge amp handling numbers, they are all full of crap.

Have you tried riding on the trailer behind the truck. If the tank is 90 Kg, that truck could pull you. Wow!

Check out my videos on my YouTube channel, can easily take my weight.

Lots more work on the tank transporter, not quite complete but nearly there.

There are a few issue I want to try and solve, the first is lack of traction. I need to work out how to lock the diff which will help over rough ground. There is no way I can fit four wheel drive but I might consider either a larger motor or dual motors.

The suspension in the tractor unit had to be strengthend by adding coil springs.

Depending on the diff style, THICK grease, candle wax to hot glue have worked for me on improving traction (all are reversible when needed).

That' a cool build.. Out intrest where did you source those wheels ? I'm considering building a AEC Matador build but sourcing wheels is proving quite a mission

Tamiya and Wedico wheels and tyres could be good place to start checking for appropriate sized trailer wheels?

Sorry havent logged in for a while and missed the post. I used 200mm wheels. Mountainboard wheels are great, are split rims plus you can add whatever tread tyres you want.

The full build log is on my Blog if anyone is interested.
It has been fun building this and more of a challenge than expected. I have managed to sort out most of the issues I had. Trailer steering is now working. I have added a second motor so now power is not a problem, will pull 200kg no issue. It weighs more than expected topping in at 130kg. Tractor weighs 80kg. Overall length = 3300mm. Width = 640mm
The wheels and tyres have been awesome and combined with the softer suspension look great when the tyres track over rough ground.
