Abstract
A cable transportation system has a pull cable; at least one transportation unit moving along a given path and connectable selectively to the pull cable by a coupling device; at least one passenger station where the transportation unit is detached from the pull cable; and an auxiliary drive device having a linear electric motor extending along a portion of the given path to move the transportation unit along the passenger station.
Claims41
A transportation system comprising:
- a transportation unit configured to move along a designated path and selectively connectable to a pull cable by a coupling device;
- and
- an auxiliary drive device extending along the designated path and configured to move the transportation unit along a portion of said designated path, said auxiliary drive device including a linear electric motor having:
- a linear stator extending along said portion of said designated path, and
- a slide associated with said transportation unit, said slide configured to be magnetically connected to the linear stator when the transportation unit moves along said portion of said designated path.
A cable transportation system comprising:
- a transportation unit configured to move along a designated path and selectively connectable to a pull cable by a coupling device;
- and
- an auxiliary drive device configured to move the transportation unit along a portion of said designated path and including a linear electric motor having:
- a linear stator extending along said portion of said designated path and including a succession of a plurality of electric coils,
- a slide associated with said transportation unit and configured to be magnetically connected to the linear stator,
- a plurality of electric current intensity and electric current frequency modulators configured to power the respective electric coils, and
- a control unit configured to supply at least one regulating signal to each of the modulators which regulate a current intensity and a current frequency supplied to the respective coils as a function of at least one of the regulating signals.
A method of operating a cable transportation system including a plurality of transportation units configured to move along a designated path and selectively connectable to a pull cable by a coupling device, and an auxiliary drive device configured to move the transportation units along a portion of said designated path and having a linear electric motor including a linear stator extending along said portion of said designated path and including a succession of a plurality of electric coils, and a plurality of slides, each slide associated with a respective one of the plurality of transportation units and configured to be magnetically connected to the linear stator, said method comprising:
- simultaneously moving at least two of the transportation units along the same linear stator.
