Abstract
An elevator has an elevator car that is guided on two mutually opposite guide rails in an elevator shaft. The guide rails each contain a U-shaped guide channel with a frontal guide surface and two lateral guide surfaces. Roller guide shoes are provided for guiding the elevator car. Each of the roller guide shoes has two rollers mounted on a common axle so as to rotate freely about an axis of rotation for guiding along the frontal guide surface of the U-shaped guide channel and a guide roller received between the two lateral guide surfaces of the U-shaped guide channel for lateral guidance. Covers are arranged upstream of the two rollers for covering the respective rollers, wherein the covers form an emergency guide.
