Abstract

The carriage which permits the direction of a trolley to be changed without changing the platform position. It has driven and steering wheels mounted in opposition which can pivot on a vertical axis and, free support rollers for the platform. There is a pivoted crown acting under the effect of driven wheels in reverse and locked and unlocked to a predetermined and variable angle. There is a sensor to give automatic steering of the trolley on active or passive track.
