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 within the hostile environment. The trolley is movable between the runway rails. The hoist with extendable-retractable cable is movable with the trolley. Bridge sensors separately determine whether the bridge has engaged a bridge home position and a bridge end position. The bridge is movable away from the bridge home position and back toward the bridge end position. Trolley sensors separately determine whether the trolley has engaged a trolley home position and a trolley end position. The trolley is movable away from the trolley home position and back toward the trolley end position. Hoist sensors separately determine whether the cable has engaged a hoist home position and a hoist end position. The cable is extendable away from the hoist home position and retractable toward the hoist 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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
