I’ve finished this build. It was pretty straightforward. The coolest part is probably the two dog clutches that change the hand crank input between lowering/raising the boom, extending the boom, and lowering/raising the hook.
The lack of solidity in Technic models this size is evident as soon as you interact (ie play) with the model. Whilst the real crane would have an especially solid feel, the model wobbles around a lot. It’s quite noticeable in the video, although the sound effects help.
