- 14 - SUMMARY Abstract Vertically and horizontally self-propelling transport equipment for persons, with friction wheels (9) which are mounted and driven at the equipment and which are pressed against the running bed by a passive force, which produces the necessary friction and is influenced by cage and load weight, and additionally by an active regulated force by means of setting elements (11). The friction wheels (9) with friction wheel drives (8) are mounted underneath a lifting carriage (2) at fulcra (6) by means of guide arms (7), and the necessary contact pressure for a low-slip drive is produced at a defined angle to the horizontal of the straight line between fulcrum (6) and contact point (x) of the friction wheels (9) in guide grooves or on guide rails (12) in the shaft (5). There are, for example, four friction wheel drives provided below a cableless cage (1). The cage (1) is carried by the lifting carriage (2) by way of vibration dampers (2). A safety device according to regulations is attached to the lifting carriage (2). For heavier cages (1) an additional carriage is provided as pulling carriage (15) with a guide device (15.1).
