摘要: A device for raising and lowering torches of flame cutting machines includes parallel swivel levers mounted about a common horizontal axis with a rod extending between the free ends of the levers and the torches mounted to the rod. A resilient restoring force is utilized to hold the torches in the driving position, while an activation arrangement is utilized for overcoming the restoring force.
