A counterweight guiding arrangement for an elevator is disclosed. It comprises at least one guide rail (10), at least one roller guide (20) configured to move along the guide rail, the guide rail comprising two lateral portions (11) defining a guide groove (12) therebetween. The roller guide comprises a guide frame (21) and at least two roller wheels (22) attached to the guide frame. Each of the roller wheels has a plane of rotation (23). The counterweight guiding arrangement is characterized in that each of the roller wheels is configured to move along a guide groove-facing surface (13) of one of said lateral portions, so that each said guide groove-facing surface has at least one roller wheel configured to move thereon. It is further characterized in that there are at least two planes of rotation of the roller wheels, the planes of rotation being at an angle to each other, and that the projections of the roller wheels on a plane perpendicular to the direction of the roller guide movement overlap at least partially. |
