Claim:
1. A method in the manufacture of an elevator, in which is formed an elevator arrangement, the elevator comprising: an elevator hoistway, a first elevator unit to be moved in the elevator hoistway, said first elevator unit including at least an elevator car, a movable supporting structure in the elevator hoistway above the elevator car, roping suspended from the supporting structure for supporting the first elevator unit to be moved, said method comprising the steps of: a) using the elevator car to transport passengers or freight; b) after step a), lifting the supporting structure in the elevator hoistway; and c) after step b), using the elevator car to transport passengers or freight, wherein in the method between steps a) and b), a step x) is performed, the step x) comprising lifting a section of the roping separately from the lifting of the supporting structure higher up in the elevator hoistway, the section of the roping being supported by a structure separate from the supporting structure and positioned higher than the supporting structure in the elevator hoistway, wherein the roping passes the structure, travelling, on a first side of the structure, to suspend the elevator car, and travelling, on a second side, opposite to the first side, of the structure, to the supporting structure, and the roping, on the second side of the structure, is fixed to the supporting structure during the step b), wherein the elevator further comprises a second elevator unit to be moved in the elevator hoistway, and in the step x), the structure that is separate from the supporting structure is movably supported on a guide rail of the second elevator unit wherein the second elevator unit is a counterweight, and wherein the roping on the first side of the structure travels to suspend the elevator car by passing through a roping pulley attached to a top of the second elevator unit, and the roping on the second side of the structure travels to the supporting structure and then to a roping storage, the roping storage releasing roping during the step x) and the step b).
