A guide rail fixing device that can increase frictional force against a guide rail without increasing the number of brackets installed on an inner wall of a hoistway. The guide rail fixing device includes: a rail bracket in contact with a bottom face of a base of a guide rail placed in the lowest portion out of multiple guide rails arranged in line in an elevator hoistway; a rail clip to clamp the base of the guide rail in cooperation with the rail bracket; and a friction plate which is in contact both with the bottom face of the base of the guide rail placed in the lowest portion and in contact with an upper end of the rail bracket, to clamp, in cooperation with a rail clip, the base of the guide rail placed in the lowest portion.

A mounting device for performing an assembly process in an elevator shaft of an elevator system includes a support component and a mechatronic assembly component. The support component moves within the elevator shaft. The assembly component is retained on the support component and carries out a mounting step in an at least partially automatic manner during the assembly process. The support component includes a fastening part that secures the support component and/or the assembly component in a direction extending transversely to the vertical, i.e. for example in a horizontal or lateral direction, within the elevator shaft.

A mounting device for performing an assembly job in an elevator shaft of an elevator system has a support component and a mechatronic assembly component. The support component is configured to be moved within the elevator shaft. The assembly component is held at the support component and configured to perform a mounting step as part of the assembly job in at least a partially automatic manner. The assembly component can be an industrial robot. The mounting device allows repetitive mounting jobs, such as drilling holes and driving in screws, etc., to be performed in a partially or fully automated manner. The mounting effort, time, and/or costs thereby can be reduced.

A method for erecting an elevator system in an elevator shaft of a building includes performing at least one lift process to adapt a usable lift height of the elevator system to an increasing height of the building. During the lift process, a drive platform, which supports an elevator drive machine and, via a flexible support, an elevator car and a counterweight, is lifted along at least one elevator car guide rail. Prior to the lift process, the at least one elevator car guide rail is elongated in the upwards direction above the drive platform and fixed to a shaft wall of the elevator shaft by at least one auxiliary support in the region of the elongation. After the lift process, the at least one auxiliary support, which then lies below the drive platform, is replaced by a final guide rail mounting which is designed differently than the auxiliary support.

A guide rail for an elevator system may comprise at least two rail elements that together form a guide rail portion having a functional running track that extends in a travel direction. Each of the rail elements may be connected to a shaft wall of the elevator system. Furthermore, the at least two rail elements may be adjacent and spaced such that the at least two rail elements can thermally expand freely in the travel direction. Additionally, the at least two rail elements in a region of the functional running track may have mutually opposite borders that have complementary profiles. An arbitrary cross section of the guide rail portion perpendicular to the travel direction in the region of the functional track may run through at least one of the two adjacent rail elements.

A guide rail for an elevator system may include at least one rail element that is fastened by at least one fastening means to at least one shaft wall of the elevator system. The at least one rail element may be mounted in a movable manner in relation to at least one shaft wall. The at least one rail element can be moved in relation to the at least one shaft wall such that a space behind the at least one rail element and the shaft wall is accessible for inspection purposes. In some cases, the fastening means includes a hinge by which the rail element can swivel relative to the shaft wall.

An elevator system, including at least one first guide rail, which is oriented in a first, in particular vertical, direction, at least one second guide rail, which is oriented in a second, in particular horizontal, direction, a plurality of rotatable rail segments, wherein at least one thereof is transferable between an orientation in the first direction and an orientation in the second direction, at least one elevator cab, which is transportable along the guide rails and which, via the rotatable rail segments, is transferable between the different guide rails, at least one third guide rail, which is oriented in a third, in particular horizontal, direction, and wherein at least one of the rotatable rail segments is transferable between an orientation in the first or second direction into an orientation in the third direction.

The composite assembly of the steel structure for lifting equipment comprised of the lifting system, into which the lower parts of vertically connected pillars connected to one another by cross-beams are fixed, with a levelling lifting system comprised of lifting plates (11) that are anchored into a concrete recess using chemical bonds via openings (15), with the structure levelling system comprising an adjusting screw (14), adjusting load-bearing nut (12), and safety nut (13), where the adjusting screw (14) passes through the opening in the lifting plate (10) welded onto the lower part of the lowermost pillar (1) of the structure. The vertical connections (3) of individual pillars (1), on the inner sides of both ends fitted with sets of openings mutually arranged at the angle of 90 degrees, are realized by inner connecting pieces (18) with fixed nuts (21), attached by Allen head screws (20) with safety washers having high resistance to spontaneous releasing due to vibrations via a set of openings. Connection of the cross-beam (2) and pillar (1), fitted with fixed integrated nuts (17), screw connections (4) is realized in the front part of the cross-beam (2) closed by the plate (4b) via oval openings (4a) on the inner side of the structure by Allen head screws (4c), supported by safety washers (4d) with high resistance to spontaneous releasing due to vibrations. The connections (4) are also fitted with mechanical protection by safety plates (7), attached by Allen head screws (22) to the fixed nuts (19) attached into the inside of the section on the side of the cross-beams (2), with corner reinforcements (6) ensuring the stability and perpendicularity of the connection (4) of the pillars (1) and cross-beams (2), further comprising a system for seating the brackets of the guide rails consisting of an oval opening (8) and a T-bolt (16), having a rectangular block (16b) in the rear part and a square block (16a) on the top of it for fixing and levelling the attached elements of the elevator.

A support device for supporting a rotary platform of an elevator. The support device includes a first form-fit engagement means at an end of a fixed first guide rail, said end facing the platform, a third form-fit engagement means at an end of a third guide rail fastened to the platform and rotatable with the latter. In an alignment of the platform to a first position, the first and third form-fit engagement means are arranged with respect such that, when the platform deflects, as around an axis arranged in a second direction, the third form-fit engagement means is supported on the at least one first form-fit engagement means.
