ABSTRACT:
An elevator installation has an elevator car and a permanent magnet linear drive system with a stationary part and a movable part, which moves along the stationary part when the permanent magnet linear drive system is controlled in a drive mode. The elevator car is arranged in a rucksack configuration. The stationary part has two inclined interaction surfaces which include an angle between 0° and 180°. The movable part comprises two units which are so arranged in common on a rear side of the elevator car and mechanically positively connected with the elevator car that in the case of drive control each of the two units produces a movement along one of the interaction surfaces in order to thus move the elevator car.
