A transport system is provided, comprising an underfloor high frequency
alternate current primary conductor for providing an electromagnetic
field extending along the primary conductor for inductive energy
transfer. The transport system includes at least one electric transport
vehicle comprising two individually controllable and individually
drivable drive wheels. At least one pick-up unit with a secondary
conductor for the inductive energy transfer is pivotable relative to the
vehicle and comprises at least one idle roller adapted for being
continuously contacted with the travel surface. The electric transport
vehicle includes a sensor unit adapted for sensing continuously a floor
track signal. A control unit is provided to control the two drive wheels
in response to signals of the sensor unit for minimizing a deviation of
the vehicle from the floor track signal.
