Title: BELT ROLLER FOR AN ELEVATOR SYSTEM
Abstract:
In an elevator system, a belt-type carrier means (5) is guided over a pulley (4, 8, 10). In this case, longitudinal elevations (33) of the belt-type carrier means (5) engage into longitudinal recesses (13) on a roller contact surface (15). The roller (4, 8, 10) has at least one retaining element (17) which is arranged laterally to the pulley contact surface (15). In this case, a distance (19) between an outermost longitudinal recess (13) and the retaining element (17) is less than half a longitudinal recess width (18) of the roller contact surface (15).
