The invention relates to a method and an apparatus for installing an elevator with-out machine room during the construction of a building, said elevator comprising at least a hoisting machine (4) provided with a traction sheave (30) and an elevator car (3) suspended by a set of hoisting ropes (28) and fitted to move along guide rails (2), and in which method at least a temporary machine room (6) movable in the elevator shaft (1) is utilized. At the final stage of installation, the machine room (6) of the elevator provided with a temporary machine room (6) is dismounted and the elevator is converted into an elevator without machine room by placing the hoisting machine (4) that was used in the temporary machine room (6), together with the hoisting ropes (28) on the traction sheave (30), into its final position in the elevator shaft (1).

The invention also relates to a method for installing an elevator provided with a machine room and suspended by hoisting ropes (15) and moving along guide rails (2) during the construction stage of building. The elevator is provided with a hoisting device (17), by means of which the machine room (4), which is initially placed in the lower part of the elevator shaft (1), is lifted through one or more floor-to-floor distances at a time in the shaft in such manner that at least the vertical forces resulting from the lifting are transmitted to the bottom structures of the building substantially via the guide rails (2) already secured.

The invention relates to a procedure and an apparatus for the installation of an elevator. According to the invention, at least one suspension element (16,17) is fixed to the upper part of the elevator shaft, to which element is fitted a suspension device (24) used to support shaft equipment during installation. The suspension device (24) is mounted on the suspension element (16,17) using a mounting tool (22) from the top floor landing (11).
摘要:
Method for constructing an elevator, more particularly an elevator that is used during the construction-time of the building, in which method the range of movement in the elevator hoistway of the elevator car of the elevator is changed in steps to extend higher in the elevator hoistway with stepped lifts of the supporting platform of the elevator car, and in which method the supporting platform is lifted higher in the elevator hoistway with hoisting means, and the support force needed for the lift is taken from the building via a support structure. In the method the supporting platform is moved in the longitudinal direction of the elevator hoistway while being supported on a support structure that is supported immovably on the building such that the point for taking support from the support structure moves upwards in connection with the lifting of the supporting platform.

The invention concerns an arrangement in the supply of rope to the speed limiter of an elevator. The arrangement comprises at least a braking device for braking the rope being supplied to the speed limiter. As new rope is being fed to the speed limiter, the new rope has been fitted to run via the braking device and under a diverting pulley in the lower part of the elevator shaft and passed further from the diverting pulley over an upper speed limiter pulley to act on the safety gear of the elevator.

The object of the invention is a method for installing an elevator, in which method the guide rails of the car are installed by fixing the guide rail sections into position from the bottom upwards. After installation into position of the lowermost guide rail section at least one working platform is built between the guide rails of the lowermost guide rail section, the guide rails of the second guide rail section are fixed as an extension of the guide rails of the lowermost guide rail section using the working platform as an aid, diverting pulleys are fixed to the top ends of the guide rails of the second guide rail section, a hoist and the rope suspension of the working platform are fitted to the working platform, in which rope suspension the hoisting rope is led at its first end from the hoist over the diverting pulleys and under the diverting pulleys that are in connection with the working platform to its fixing point of the second end on the working platform, and the working platform is lifted to the next working height by means of the hoist and is locked into position.
