Method for installing the hoisting roping of an elevator

Method for installing a hoisting roping of an elevator, in which method

• a first elevator unit to be moved is disposed at a suitable point in an elevator hoistway, and a second elevator unit to be moved is disposed at a suitable point in the elevator hoistway, said first elevator unit being an elevator car and said second elevator unit being a counterweight, or vice versa,
• the hoisting roping is arranged to travel over a diverting pulley supported in its position in a manner allowing its rotation and to support the elevator units while supported on the diverting pulley in question, by connecting a first section of the hoisting roping on a first side of the diverting pulley to support the first elevator unit and by connecting a second section of the hoisting roping on a second side of the diverting pulley to support the second elevator unit, such that the first and/or the second section of the hoisting roping support(s) their elevator unit(s) via a diverting pulley system,
• wherein in the method the first section and/or the second section of the hoisting roping is/are connected to their elevator units via the diverting pulley system of the elevator unit such that when the diverting pulley system is still separate from the elevator unit, the section in question of the hoisting roping is arranged to travel under the diverting pulley system of its elevator unit, and the diverting pulley system is lowered, when reeved, downwards into the proximity of its elevator unit, after which the diverting pulley system in question is fixed to its elevator unit.
