The invention relates to an elevator system (10) comprising an elevator cab (14), which is arranged for vertical motion in an elevator shaft (12); a traction medium (16) for lifting and lowering the elevator cab (14), wherein the traction medium (16) is guided around at least one roller (42) fastened to the elevator cab (14) and the traction medium (16) is fastened only at ends (22a, 22b); a reservoir (20) for the traction medium (16), wherein the reservoir (20) comprises at least one first deflection axis (44a, 44b) and at least one second deflection axis (46a, 46b), around which the traction medium (16) is guided alternately between a first deflection axis (44a, 44b) and a second deflection axis (46a, 46b) such that a segment (30c) of the traction medium (16), the length of which segment depends on a distance of the at least one first deflection axis (44a, 44b) and the at least one second deflection axis (46a, 46b), is accommodated in the reservoir (20); and a fastening unit (48), to which the at least one second deflection axis (46a, 46b) is fastened, wherein the fastening unit (48) can be fastened at various positions in the elevator shaft (12) such that a distance between the at least one first deflection axis (44a, 44b) and the at least one second deflection axis (46a, 46b) can be set in order to define the length of the traction medium (16) accommodated in the reservoir (20).
