Claim:
A method for modernizing an elevator, wherein the suspension of an old elevator is modified, the old elevator comprising: an elevator car; a counterweight; an elevator hoistway; a hoisting machine with a traction sheave in a machine room above the elevator hoistway, for moving the elevator car in the elevator hoistway via the hoisting roping; old hoisting roping comprising one or more hoisting ropes, the old hoisting roping passing around the traction sheave and connecting the elevator car and the counterweight, and passing from the traction sheave to the elevator car or the counterweight, and to a rope clamp that is in connection with the elevator car or the counterweight, via an aperture in the floor of the machine room, said method comprising the steps of: arranging a first rope clamp and a second rope clamp in a top part of the elevator hoistway such that the first rope clamp and the second rope clamp are supported by a same support element supported in its position; removing the old hoisting roping; and installing a new hoisting roping by guiding the new hoisting roping to pass around the traction sheave and to connect the elevator car and the counterweight, and guiding the new hoisting roping to pass from the traction sheave to the elevator car or the counterweight via the aperture in the floor of the machine room, the new hoisting roping comprising a plurality of ropes, including: a first part that is guided to pass to the elevator car or the counterweight to a first diverting pulley that is in connection with the elevator car or the counterweight, and onwards from the first diverting pulley back upwards to the first rope clamp in the top part of the elevator hoistway; and a second part that is guided to pass to the elevator car or the counterweight to a second diverting pulley that is in connection with the elevator car or the counterweight, and onwards from the second diverting pulley back upwards to the second rope clamp in the top part of the elevator hoistway.
