I did a lot of fixing. there were problems with the electric feed through the slewing ring, the gearbox jammed and I fixed the main winch, which did not run smoothly. One of the outriggers was not working and so on.
I also started designing the telescoping mechanism. i will be using the oil tanks on the side of the boom to hide 2 motors, which will drive a single spindle, which will be able to rotate 45 degrees either way and in this way pick up one of the 3 sections, basically simplified way the modern cranes work.
I made a few videos, not great quality, but they show the first trials.
