Abstract
An elevator has a mechanical linear drive arranged laterally at an elevator shaft head to drive at least one belt that moves a car and a counterweight in the shaft. The belt is fixed in the shaft at opposite ends and extends about a drive wheel of the elevator drive. Deflection rollers of the drive determine the angle of encirclement of the belt on the drive wheel.
