Making Mobile Crane - Using Planetary Gearbox

Tools we use - www.amazon.com...
Making your own workshop crane may be pointless for many of you when you can go to Habrot Freigh and buy a new one for little money.
However, I decided to do it myself for several reasons.
I adjusted the dimensions to fit my small and low workshop.
The wheels are small, so I can roll them under my tables, which gives me greater opportunity to precisely place heavy elements.
I used a winch instead of a hydraulic jack so I can pull heavy things that are out of reach of the crane
