An elevator arrangement, which comprises:
- an elevator hoistway;
- an elevator car, which is arranged to travel in the elevator hoistway;
- a counterweight;
- a movable supporting platform above the elevator car;
- suspension roping, which is connected to the elevator car and to the counterweight, and supports the elevator car and the counterweight while suspended from the supporting platform;
- and
- a hoisting machine and traction roping that are separate from the supporting platform, which hoisting machine is in power transmission connection via the traction roping with the elevator car and with the counterweight.
A method in the fabrication of an elevator, comprising the steps of:
- installing the elevator car, and the counterweight, and the movable supporting platform in the elevator hoistway;
- installing the suspension roping to connect the elevator car and the counterweight, and to support them while suspended by a movable supporting platform supported in its position above the elevator car;
- installing the hoisting machine and traction roping separate from the supporting platform, such that the hoisting machine is in power transmission connection via the traction roping with the elevator car and with the counterweight,
- taking the elevator car into use to serve passengers and/or to transport goods;
- removing the elevator car from said use
- changing the service range of the elevator car to reach higher up in the elevator hoistway by lifting the supporting platform higher up in the elevator hoistway;
- taking the elevator car back into said use.
