The invention relates to a rail vehicle (1) having a machine frame (2) supported on on-track undercarriages (4), on both sides of which are arrangedin the longitudinal direction (3) of the rail vehiclecrane rails (8) for a mobile gantry crane (11). In this, for lifting or lowering of the gantry crane (11), a crane rail section (12) of the respective crane rail (8) is arranged to be vertically adjustable by a drive (18). In this manner, contrary to the prior art, a higher gantry crane (11) can be used without violating a given clearance profile during transfer travel.

A maintenance vehicle has a vehicle frame, supported on on-track undercarriages, on which are arranged two side walls extending in a longitudinal direction of the vehicle and adjustable with respect to one another and relative to the vehicle frame in a transverse direction of the vehicle by way of drives. The vehicle is equipped with at least one load crane which is displaceable on a crane guide that extends in the transverse direction of the vehicle. The crane guide, designed to be elongatable in the transverse direction of the vehicle, is connected at each end to a side wall.

A transport vehicle includes a container for receiving bulk material which is disposed on a vehicle frame and is pivoted, together with a bottom conveyor belt and a third conveyor belt, relative to the vehicle frame about a pivot axis extending in a longitudinal direction of the vehicle in order to maintain a horizontal conveying plane, relative to a transverse direction of the vehicle, for the bottom conveyor belt and the third conveyor belt, independently of a transverse inclination of the track. Thus, a problem-free bulk material transport is possible even in the event of a transverse inclination of the track. A method of loading and unloading a transport vehicle which is mobile on a track is also provided.

Systems and methods for using a mobile crane assembly are provided. The mobile crane assembly includes a mobile crane having a first truss assembly and a second truss assembly spaced apart and movable relative to one another. The first truss assembly and the second truss assembly are each coupled to a rail car end assembly. The mobile crane further comprises an upper gantry assembly movable along the first truss assembly and the second truss assembly. A flat cart is coupled to the rail car end assembly, and a material handling cart is received upon the flat cart and is configured to move between the flat cart and the rail car end assembly based upon input from a controller in electrical communication with the upper gantry assembly.
