Abstract: A self-maintaining crane system including a bridge, a trolley, a hoist, and sensors for use within a hostile environment, such as a wastewater treatment facility, is presented. The bridge is movable along a pair of runway rails. The trolley is movable between the runway rails. The hoist with extendable-retractable cable is movable with the trolley. Bridge sensors determine whether the bridge has engaged home and end positions. Trolley sensors determine whether the trolley has engaged home and end positions. The bridge and the trolley are movable between home and end positions. Hoist sensors determine whether the cable has engaged a hoist home position and a hoist end position. The cable is extendable away from the home position and retractable toward the end position. Sensors facilitate automated movement of bridge, trolley, and cable so as to minimize functional impairment of the crane system by the hostile environment.

Abstract: A dumpster handling system is operated to support and move a roll-off dumpster back and forth underneath a point of material discharge for the filling of the dumpster. The system operates to move the dumpster so that the material is deposited at different points into the interior of the dumpster to achieve an even distribution of the load of material throughout the dumpster.
