Abstract
A method of modernizing an escalator using modular components. The mechanical and electrical parts of an existing escalator are removed, leaving only the structural truss framework and cross members as well as all external parts, such as external panels, that interface with the building. A single module is placed at the top of the escalator and another module at the bottom. A plurality of incline modules are placed in the central inclined part of the escalator, at each cross member. By utilizing these modules, the assembly of the escalator is simplified. Furthermore, an entirely new escalator system using the latest technology may be installed rather than merely installing new parts in an old system.
