Diy 1100lbs workshop crane

Hello people! Today I wanted to show the construction of my crane. I built it to lift heavy things on my welding table. The rotating parts consist of two radial and one axial bearing. I designed the crane for 500kg but I have also lifted 650kg with it (my welding table) without a minimal bending. A small project, which increases my possibilities in the workshop and saves my back. :D Have a good One!
