Problems solved by technology

[0004] In the conventional hoist installation method, if the hoist is directly above the hoist, the hoist cannot be lifted above the position of the hoist. In addition, when the hoist is installed outside the track, it is necessary to consider the relationship between the rail support member and the hoist. The collision of equipment (metal cables, etc.) may limit the actual use
In addition, in the method of installing the crane on the track support member, the size of the track support member varies depending on the distance between the track and the building, so the same supplies cannot always be used
In addition, since the rail support member originally supports the load in the horizontal direction, when it is desired to support the load in the vertical direction with the rail support member, it is necessary to redesign the rail support member in consideration of such a load, which may cause the Parts upsizing

Abstract

Embodiments of the invention relate to a method for mounting a winch to the interior upper portion of a lift channel of an elevator, requiring no horizontal movement of the winch and thereby realizing labor-saving operation. The method of the embodiments comprises a winch arrangement step (S3) of arranging a crane to the neighborhood of the top of a track; a step (S4) of mounting a winch-supporting-beam fixing tool onto the track; a step (S7) of imbedding the crane in such a manner to be capable of sliding in the vertical direction relative to the track; a step (S8) of loading the winch onto a lifting platform; a step (S9) of lifting the lifting platform and the winch via the crane so that the winch upwardly penetrates between two winch supporting beams; a step (S11) of horizontally moving the winch supporting beams so as to be located below the foot portion of the winch; and a step (S12) of bringing down the lifting platform and the winch via the winch and loading and fixing the winch on the two winch supporting beams.

Description

[0001] This application is based on Japanese Patent Application No. 2010-189036 (filing date: August 26, 2010) and enjoys priority from this application. This application incorporates the entire content of this application by reference. technical field [0002] The invention relates to a method of installing a winch in the upper part of the hoistway of an elevator. Background technique [0003] As a method of installing the elevator hoist near the ceiling in the hoistway, there is known a method in which a crane is installed on the top of the hoistway, and a hoist is lifted for each stand using rails for lifting guidance. In addition, as another method, there is also known a method in which a crane is installed on a rail support member, and the hoist is first raised to a target height and then horizontally moved to a predetermined position. [0004] In the conventional hoist installation method, if the hoist is directly above the hoist, the hoist cannot be lifted above the ...
