ABSTRACT OF THE DISCLOSURE The stair-climbing system that is suitable, for example, for wheelchairs has two pairs of running wheels that can pivot about separate but commonly driven eccentric drive shafts and can thereby be landed on or taken off from a step. When this is done, braking systems associated with the individual running wheels can block the individual running wheels during their piv- oting movement so as to prevent any accidental movement of the wheelchair over the edge of a step.
