Modified this bowl lift by adding 4 feet to its height and travel to accommodate a modification to the production line which required a higher discharge point. Commercial food production line.

Wire Rope Drum
Close to 20' in diameter this wire rope drum is for a lock system at a dam on the mighty Columbia River, after many decades of service a rebuild was required. This is one of the only machines in the region that can handle a part this size, and it is CNC controlled which makes the machining of the internal features of the bore much more likely to be successful since there is no way to see what is happening 6 feet down inside the bore while the outside diameter is spinning past you at over 1,000 feet per minute.
