  • Patent number: 8613255
    Abstract: A mass transit monorail uses an I-beam rail structure having an upper flange portion spaced apart from a lower flange portion, the flange portions joined by a vertical web portion. A frame of a vehicle has a pair of supporting wheels contacting the rail on a first side at an intersection of the web portion with the lower flange portion. A third wheel contacts the upper flange portion on a second opposing side of the rail. The vehicle moves along the rails which form a semi-continuous in-line track. A plurality of such tracks are positioned in parallel to make up a transport corridor with plural right-of-ways where vehicles may move in opposite directions passing each other. The rails are flexible enough to enable a vehicle to move from one semi-continuous in-line track to an adjacent semi-continuous in-line track.

    Abstract: A method for producing a beam for a travel way in a track vehicle system includes fabricating the beam at a production facility with dimensions corresponding to erected dimensions the beam will have at its construction site, or within a predetermined deviation from the erected dimensions. The beam is positioned in the position it will have in its erected state in the travel way at the construction site. Positions for connection points are measured and defined on the beam for appurtenances so that such appurtenances and functional surfaces will have a desired relative position on the beam in its erected state at the construction site. The connection points are reworked by adding or removing material as required so that upon mounting the appurtenances to the beam at the connection points, the appurtenances and functional surfaces will have the desired relative position on the beam at the construction site.

For this purpose, the industrial truck (1) stands on the underlying surface by way of a front steering-roller pair (3) and a rear fixed-roller pair (5) and is kept on track by a guide roller (9) butting against the rail (6). In the region of a curved element (12), the rail (6) has an elevation, with result that there is an increase there in the propulsion force which can be transmitted by a friction wheel (8) of the friction drive (7). An introduction aid (11) allows the guide roller (9) to be aligned without difficulty in relation to the rail (6). The industrial truck (1), rather than being bound to fixed cyclic operation by its friction drive (7), can be specifically accelerated or decelerated. In the event of malfunctioning of the industrial truck (1), the latter can easily be moved manually.

    Abstract: The invention is directed to a recessible guide rail for guiding a wheel-supported vehicle along a roadway structure. The vehicle is equipped with flangeless wheels or the like for coacting with a side wall of the rail to laterally guide the vehicle along the roadway structure. It is necessary to remove the guide rail from time to time in order to realize the advantages of such a vehicle on its special rail-like roadway structure and on conventional roads. With the guide rail removed, it is possible to remove the laterally guided vehicle from its roadway structure. Also, it is possible to permit other vehicles to cross the special roadway structure of the guided vehicle. With the invention, supporting devices having lateral holding pockets which can be moved in elevation are installed where the guide rail is to be removable. Straight or curved guide rail segments which can be made of steel reinforced concrete are inserted into the pockets.

  • Patent number: 4150625
    Abstract: In overhead cranes of the kind including a box girder fabricated of elongate plates and torsionally loaded by a trolley running on three rails respectively at three corners of the box girder, the structure of the box girder is usually such that flanges project from the corners thereof and prevent proper support of the rails in optimum corner positions in alignment with the walls of the girder. This problem is now solved by providing a rail with an elongate flange and securing the rail and flange respectively to marginal portions of a pair of adjacent plates of the box girder. In this way the rail can be secured in optimum position at the corner of the girder and forms with the flange a member which encloses the corner flange and serves as a stiffener or reinforcement for the corner. In a preferred construction the rail and flange are the respective arms of a generally V-section elongate member enclosing the corner of the girder.
