The whole thing probably weighs close to 50lbs. But top rail comes of. Buttom is very light. I put the whole thing in the truck by myself. Its is pretty easy for one man to push it up. Rail rides on wheels that are mounted on the base. 6 wheels at 4″. Clearance is 14″ I didnt want to go any higher bc it would be harder to push the kart up for single person. Outside size is 60×60 each strip of expanded metal measures at 12″.
