Bell 50 ton Dumper - ADT

[elliot330]

It lives! The oil arrived today, poured it in, cycled the cylinders a few times, watched all the air come out and voila, it steers and the bucket lifts up… what more could you want! Apart from a loose fitting, there were no other leaks!

Set it up to run 10 bar to start with, but the steering was very slow, plus it takes a while to get used to driving something that bends in the middle! Upped the pressure to 12 bar and very happy now… It can go a lot higher, but not needed at the moment.

Programmed the transmitter to only activate the pump when needed, that took a while to get my head around!

At least it moves and steers… and empties!

I do need a better speed controller though it thermal overloaded towards the end…!

Couple of boring videos…

Loaded the bucket with 6 x 1.5 litres (which I think equates to 9kgs in weight?) of Evian’s finest and it lifted it with ease…

Well happy!
