The invention relates to an overspeed governor tension sheave assembly in an elevator comprising at least an elevator car arranged to run along the guide rails and controlled by a speed governor assembly that is coupled to the elevator car through a governor rope forming a closed loop running over a governor sheave, and under a governor tension sheave being a part of the overspeed governor tension sheave assembly. The overspeed governor tension sheave assembly is equipped with a monitoring device that has indicating means for indicating the need for adjustment the position of the overspeed governor tension sheave assembly.

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 the hoisting roping of an elevator, in which method the hoisting roping of the elevator is lifted upwards into the elevator hoistway by means of a hoisting device. The hoisting roping is lifted upwards into the elevator hoistway in steps such that at least one rope of the roping is lifted by pulling it to the height and the aforementioned at least one rope is fixed to the elevator hoistway or to another fixed structure of the building, at least one of the ropes of the roping that is at the height and was lifted in phase is detached, at least one rope detached in phase is lifted by pulling it to the next height and the aforementioned at least one rope is fixed to the elevator hoistway or to another fixed structure of the building.

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.
