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.
