Abstract:     The device, e.g. a wheelchair, can climb stairs, and has at least one running wheel supporting a load. At least one stair wheel (14) is fastened to the load, pivoted about its centre. The stair wheel consists of two or more individual wheels (27,28,29), turnable in a holder. The pivot centre maintains a distance to a bearing of an individual wheel, the length of which is determined by the height of at least one of two subsequent steps. The individual wheels roll on a plane (11) travelled by the running wheel. Each wheel may be locked within its holder, and each wheel has a locking brake within the holder. This locks the individual wheel, and permits pivoting of the holder about the bearing.
