help construction jib crane design for workshop

Oh, I see. I was wondering if you designed these and if so, how did you calculate the math and geometry to know the load rating?
[ Oh, capisco. Mi stavo chiedendo se avessi progettato questi e, in caso affermativo, come hai calcolato matematica e geometria per conoscere la valutazione del carico? ]

I have knowledge of traditional engineering and was wondering if you did the calculations yourself or, if you used a computer design tool.
[ Ho conoscenza dell'ingegneria tradizionale e mi chiedevo se hai fatto i calcoli da solo o, se hai usato uno strumento di progettazione per computer. ]

I have to speak with a turner to make me build the hinges to tie the pillar to the swivel beam, I think I have to insert ball bearings or bushings bushings, what do you advise experts?
 
I made an A frame once and discovered real fast that solid hard rubber tires were a mistake. Be sure you use steel or nylon covered steel wheels. The solid rubber ones would flatten out with a load on it...lol made it difficult to roll :-(
