An elevator includes a car, a counterweight, a suspension working together with the car and the counterweight, and a wheel at least partially wound around by the suspension, wherein the suspension comprises a tie beam arrangement made of two tie beams and a shell encasing the tie beam arrangement, said shell comprising a longitudinal structure in an area of an outer surface partially winding around the wheel, and wherein the ratio of the width of the suspension to the height thereof is greater than one and less than or equal to three. The wheel comprises a groove for guiding the suspension on the sides, in which the suspension is at least partially received, and the groove floor thereof being formed flat. The shell is coated, at least in areas, on the outer surface thereof, wherein the coating optionally has a friction-reducing, friction-increasing, and/or wear-reducing effect.
