Abstract: A counterweight for an elevator system has an asymmetrical cross section in a horizontal sectional plane. The asymmetrical cross section results in an improved connection of the counterweight to a guide rail, a reduction in a number of components, in particular guide rails, for the elevator system, and a reduction in an installation space for the elevator system thereby simplifying installation of the elevator system.

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.
