Transporting system with a floor conveyor device guided on guide rails

A transporting system, comprising;

• guide rails which laterally define a travel path that has branches;
• a floor conveyor vehicle having a front and back, as seen in a travel direction, and which is guided by the guide rails and has two longitudinal sides;
• a pair of guide rollers which are arranged at each of the longitudinal sides of the vehicle so as to engage with the guide rails at least on one side, the pair of guide rollers including inner and outer guide rollers;
• switching means for changing the travel path at a branch, the switching means being arranged at the vehicle and including a swivel drive for the outer guide rollers of the pair of guide rollers, the outer guide rollers being supported on the vehicle so as to be swivelable between a guidance position, in which the inner and outer guide rollers engage with the guide rail, and an open position in which the outer guide rollers release the guide rail;
• two steering wheels arranged at the front of the vehicle;
• two supporting wheels arranged at the rear of the vehicle, the outer guide rollers being arranged between the steering and supporting wheels so as to be offset toward the steering wheels at the longitudinal side of the vehicle;
