And here the finished, pre-assembled bucket ladder on the excavator.
When I look at the result now I have to say: the builders of the excavator knew what they were doing. Although the construction seems to be quite fragile, it is surprisingly stable, even in the model.

Holy cats, that is some terrific work! The construction of the spoked rollers alone is impressive!

Thanks, guys, for reading along.

Now a few smaller attachments have to be realized.
Let's start there with the winches for adjusting the bucket ladder.

Phew, that is some nice work. Just for nitpicking: Did you manage to get those helically toothed gears visible inzthe prototype pic? It's not obvious from the picture.

Cheers,
