ABSTRACT:
A lift for inclined or vertical operation has a pair of guide rails that run parallel to one other, on which guide rollers run that are mounted on swivel plates so that they can swivel and contact the rails from opposite sides. At least one guide roller on each swivel plate is designed as a drive roller. The periphery of the drive roller is pressed against a respective engagement area of the rail by a spring force in such a way that the drive force of the drive roller is primarily transferred to the rail by friction.
