ABSTRACT:
A telescoping bridge crane system arranged to be mounted over a floor of a structure, e.g., a vehicle trailer. The system includes a pair of enclosed mounting tracks for slidably supporting a runway frame. Trucks are located within the mounting tracks to move therein. Each truck includes a hanger. The runway frame also includes two enclosed tracks which are directly supported by the hangers so that they are located beside and parallel to the mounting tracks. A bridge section is mounted between the enclosed tracks of the runway frame by another pair of trucks.
