With the two recent posts about jib cranes for workshop applications , I have started to give some thought to constructing a 3 to 5 tonne bridge crane for moving things in a small shop I use .
It would need to have a low profile for the trolley and the beams only need to span about 3.5 metres , there is 3metres of space under the ceiling .
Anyone know of links to sites which could help with design , I want to get some idea of the required steel sizes to get an estimate of cost.
Either that or I could wait for one to come up on Ebay or similar sites ,but then it would need to be either cut down or extended to fit the space.
