How is the Walking crane an industrial machine?

Answer 1

They are a product of heavy industry, are -pre-assembled in factories, then field stripped and taken out to the job site ( they are far too cumbersome to move there under their own power) Certainly they are an industrial product. These machines werfe invented back around l9l3, too late for the Panama Canal but very effective in operating in swamps and such job sites as strip mines. In some categories they are the world"s largest crane-type machines, in the Dragline role. My dad saw a steam walking crane that had a huge cab and stack, and of the walking type ( the ground shook when that thing moved!) a drawback to the type is they cannot lift or carry loads when in motion, which is not a problem in a strip mine, quarry, or swamp, but would be a serious handicap say, in a ship yard. They were developed by the Monighan Machine company, later acquired by Bucyrus. Only a relative handufl of manufacturers have made these huge and cumbersome machines: Monighan, Bucyrus-Erie, Marion power shovel, P&H and Page- plus those evolved in the Soviet Union.
