Not such a new idea, but clever nevertheless
The Rolls-Royce heavy gang laid down a 30 foot vertical broach for transport up to one of their Scottish factories by building an ice block wall from the entire output of the Derby ice factory and pulling it onto the wall to allow the blocks to melt and lower it onto one of their low level machine skates.
After the wall had melted they jacked up the foot end, slid another skate in underneath and rolled the machine out of the shop down the gangway between all the lathes and milling machines
The Ice factory is now no more, having burnt down I believe in the late 1960s
