The disclosure relates to a method for erecting a supporting structure of a passenger transport system configured as an escalator or moving walkway. The supporting structure is constructed between two support points of an existing structure using a 3D welding robot system by depositing welding material.

A method for generating at least one installation operation for at least one on-going installation process of at an installation site includes obtaining site information of the at least one ongoing installation process at the installation site from a site control unit arranged at the installation site, obtaining site information gathered from one or more previous installation processes at one or more other installation sites from one or more external databases, defining at least one installation operation for the at least one ongoing installation process based on the site information of the at least one ongoing installation process and the site information gathered from the one or more previous installation processes, and generating at least one signal including an instruction to perform the at least one installation operation for the at least one ongoing installation process to the site control unit. A computing unit, an installation support system, and a computer program performing at least partly the method are disclosed.

An illustrative example embodiment of an assembly includes a first platform and at least one first brace associated with the first platform. The first brace is configured to engage a surface in or near a hoistway for supporting the first platform in a vertical location near the surface. A portion of the first brace is moveable relative to the first platform between an extended position for engaging the surface and a retracted position for allowing the first platform to move relative to the surface. A second platform is vertically spaced from the first platform. An adjustment mechanism associated with the first platform and the second platform facilitates adjusting a vertical spacing between the first platform and the second platform.
