Pneumatic Air Saturn Tractor Paint Spray Booth Trolley + Bridge Crane System

Condition: Used Three Tractors, shown here still in place for operation. They have been taken down, with hoses left intact, as they were in operation. What is selling are the "orange items" in the graphic illustration photo, plus a 6-lever pendant that runs them and an air hoist, if you add a hoist of your own to the system. -They run on 90 to 100 PSI air pressure. Speeds are 0 to 35 feet per minute -It says they are 1000 lb capacity, and since they don't lift the item, I think this means how much pushing force they have to act as prime mover for a crane/trolley, etc. You can call the maker for more info, if you want to, as I am only using common sense to assess this.
