A method for constructing an elevator into a destination location from a plurality of prefabricated elevator modules includes fabricating a plurality of elevator modules, in particular at a location apart from said destination location. The fabricating includes providing one or more module frames having a longitudinal axis; positioning one or more of the module frames in horizontally oriented position, wherein in the horizontally oriented position the longitudinal axis is horizontal; and while the one or more module frames are in the horizontal position, performing installation work on said one or more module frames. The method includes arranging the modules into the destination location on top of each other such that said modules are in a vertically oriented position.

An elevator system includes at least one elevator car that is configured for traveling in a hoistway along a longitudinal direction (L) between a plurality of landings; at least one tension member for supporting and driving the at least one elevator car; and a guiding structure. The guiding structure comprises at least two guide rails provided in the hoistway for guiding the movement of elevator car and/or of a counterweight in the hoistway; and at least one guide rail bracket extending along a transverse direction between two of the at least two guide rails for the coupling two guide rails with each other. The at least one guide rail bracket includes a recess that allows the at least one tension member to pass the at least one guide rail bracket by extending through the recess.

Even when designing drivetrains for elevator installations, an advantageous compromise between required resources and achievable technical (performance) data is desirable. Especially in the case of drivetrains with a belt drive, the shaft interacting with at least one belt at a driving zone requires structural optimization in order to be able to make use of improvement potential including with regard to further components of the drivetrain. According to the disclosure, the shaft has an absolute shaft length which is predefined by length dimensioning with reference to the width of the driving zone. In this way, a particularly advantageous compromise on the basis of length dependency and optionally in addition also of diameter dependency can be found, in particular in terms of optimization concerning both the material-machining outlay and smallest possible dimensions, wherein the respective drivetrain, on the basis thereof, can also be designed for different applications.
