advice on construction of a gantry crane frame for a portable demountable hoist
hi, i am a farmer, for personal reasons i would like to make a frame similar to the one for swings, i.e. a portal frame, i need to hook and hang a chain hoist. i know that there are safety regulations, but i dont have to lift heavy weights of just 500kg. if it were possible i would like to know how to size the base, the columns and the beam. thanks
dimensions would be 2.50 meters high, i think 8 feet wide and high
load capacity 500kg, could it also be made tubular instead of the H rail on which the trolley moves any advice? thanks best regardsgruetta a portale officina.png
