Elevator (1, 2), comprising: -a car (10) of the elevator and a counterweight (11) that are to be moved reciprocally; -at least one roping or belting (51) traveling via a top pulley assembly (12, 13) for connecting the car (10) of the elevator and the counterweight (11) to each other via the top pulley assembly (12, 13); -at least one roping or belting (52) traveling via a bottom pulley assembly (14, 15) for connecting the car (10) of the elevator and the counterweight (11) to each other via the bottom pulley assembly (14, 15). At least one roping or belting (52) traveling via the bottom pulley assembly (14, 15) is pretensioned or can be pretensioned. An improvement for reducing elongation of the roping or belting of an elevator in a loading situation of the car of the elevator is produced when an elevator (1, 2) according to the invention is used in such a way that at least one roping or belting (52) traveling via the bottom pulley assembly (14, 15) is pretensioned, in which case owing to the pretensioning at least one roping or belting (51) traveling via the top pulley assembly (12, 13) and at least one roping or belting (52) traveling via the bottom pulley assembly (14, 15) interact in such a way that the elasticity of the connected roping or belting (51, 52) to be formed in this way decreases compared to the situation before pretensioning.
