Abstract

The object of the invention is an installation arrangement for an elevator in an elevator hoistway, which installation arrangement comprises at least a suspension member aligned downwards from the top part of the elevator hoistway, in connection with which suspension member is, at least during the installation of the elevator car, an installation hoist arranged to move while supported by the suspension member, and in which installation arrangement at least the guide rails of the elevator and the elevator car traveling guided by the guide rails are installed in the elevator hoistway. An auxiliary hoist provided with a hoisting means is fitted onto the suspension member, which auxiliary hoist is arranged to move reciprocally in the vertical direction along the suspension member.

First claim

1 . Installation arrangement for an elevator in an elevator hoistway, which installation arrangement comprises at least a suspension member aligned downwards from the top part of the elevator hoistway, in connection with which suspension member is, at least during the installation of the elevator car, an installation hoist arranged to move while supported by the suspension member, and in which installation arrangement at least the guide rails of the elevator and the elevator car traveling guided by the guide rails are installed in the elevator hoistway, wherein an auxiliary hoist provided with a hoisting means is fitted onto the suspension member, which auxiliary hoist is arranged to move reciprocally in the vertical direction along the suspension member.

2 . Installation arrangement for an elevator according to claim 1 , wherein the installation hoist and the auxiliary hoist are fitted onto the same suspension member, and in that the traction sheave of both hoists is arranged to move the hoist along the suspension member with its rotational movement.

3 . Installation arrangement for an elevator according to claim 1 , wherein the suspension member is a toothed belt.

4 . Installation arrangement for an elevator according to claim 1 , wherein the toothing of the suspension member on the surface transmitting the kinetic energy of the suspension member is with respect to the longitudinal direction of the suspension member essentially one of the following: transverse and straight; transverse and curved; inclined in one direction; inclined in two directions; a V-shaped model, either open or solid from the tip; or some other suitable shape.

5 . Installation arrangement for an elevator according to claim 1 , wherein the suspension member is V-shaped in its cross-section on the contact surface on the traction sheave.

6 . Installation arrangement for an elevator according to claim 1 , wherein the installation hoist and the auxiliary hoist each comprise their own traction sheave, which in terms of its outer rim is configured to correspond to the force-transmitting part or surface of the suspension member.

7 . Installation arrangement for an elevator according to claim 1 , wherein the auxiliary hoist is arranged to move on the suspension member in relation to the installation hoist.

8 . Installation arrangement for an elevator according to claim 1 , wherein the hoisting means of the auxiliary hoist is adjustable in length or is replaceable according to different hoisting purposes.
