  • Patent number: 6418855
    Abstract: An industrial truck (1) is driven by a friction drive (7) acting on a rail (6). 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.

  • Patent number: 5528113
    Abstract: A loosely coupled inductive power transfer system suitable for transferring power to a mobile conveyer platform or a vehicle has pick-up coils wound on flux concentrator(s). One or more large flat horizontal ferrite cores 607, 608 are used to concentrate the horizontal component of magnetic flux from an extended volume into one or more secondary or pick-up coils 613. Each shock-resistant core comprises an array of many individual strips of ferrite held in close contact. One, more usually two, or perhaps more resonant pick-up windings are wound about each core and each winding has a shorting switch (within 602, 603 . . . ) placed across it. A controller 601 connects a controlled output voltage on to an output bus 605, 606 from the best-placed pick-up winding on any one core at any moment, while holding the others in a shorted hence inactive state.

  • Patent number: 4941555
    Abstract: An electric monorail conveyor wherein the vehicles are suspended from and advance along an elongated guide rail. The electric motor of each vehicle receives current from a third rail which is adjacent the guide rail and includes first sections alternating with second sections at locations where the vehicles are to be brought to a halt. The second sections are galvanically separated from the first sections and receive low-frequency current from a frequency converter which can reduce the frequency when the motor of a vehicle is electrically connected with a second section. This renders it possible to arrest the vehicles in predetermined positions with a tolerance of not more than .+-.2 mm.
