Abstract: A safety brake for a traveling body in an elevator system brakes against a brake rail oriented in a traveling direction. The safety brake includes a housing with a catch element and a brake pad attached to the housing opposite one another. The catch element is mounted on the housing such that an application movement of the catch element relative to the housing is possible, and the application movement reduces an opening width between the brake pad and the catch element. At least the catch element or the brake pad has a notch for fitting around a protrusion of a brake rail during braking. The opening width corresponds to at least twice the depth of the notch.

Abstract: A positioning aid positions a nut on a guide rail of an elevator system, the guide rail being formed as a hollow rail, the hollow rail having a plurality of elongated holes arranged one behind the other in the longitudinal direction of the hollow rail in order to be fastened to a guide rail holder. The positioning aid includes an elongate fastening portion to which at least one nut is fastened and which is dimensioned such that it can be passed through one of the elongated holes together with the at least one nut and moved within the hollow rail. The positioning aid also includes a holding portion for holding the fastening portion, the holding portion being fastened to one end of the fastening portion and being configured to be wider than the elongated hole.

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.
