I Made a Bridge Construction Vehicle According to videos on Youtube

I made this bridge construction machine after watching a video of it working on YouTube 5 years ago. I designed it myself, simulated its operation and made it myself, without any documents or drawings. It was completed in 30 working days, and it actually worked very well. At that time I was very proud and happy, but it really didn't bring me joy after I posted it on my Youtube channel. Because, as you can see, it didn't get as many views as the other videos I posted at the time. And today, I want to convey what I have done through the video of this machine, and look forward to receiving your welcome.
Here is a video that fully demonstrates how I made this machine.
