Seen here is the SpyderCrane URW295 being lowered threw a 97 inch top vent opening of a water treatment plant digester, in Cambridge, Ontario, Canada.
The machine was then used to remove and replace the piping and valves around the inside perimeter of the digester.
The URW295 saved the contractor 3 weeks labor on this project!
