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.
Claims14
A method of modernizing an escalator comprising:
- removing mechanical and electrical components from an existing escalator system, leaving a truss framework including cross members from the existing escalator system;
- installing a first module in said truss framework at a top of the escalator;
- installing a second module in said truss framework at a bottom of the escalator;
- installing a plurality of incline modules between said first module and said second module, along an incline portion of said escalator, including placing each incline module just inside said truss framework and attaching a horizontal portion of each incline module to one of said cross members;
- and
- installing track between said first and second modules on said plurality of incline modules.
A modernized escalator system, comprising:
- a truss framework from an existing escalator installation, including cross members;
- a first module containing a drive station mounted at one end of said truss framework;
- a second module including a reversing station mounted at an opposite end of said truss framework;
- a plurality of incline modules placed inside said truss framework, each having a horizontal portion connected to a cross member of said truss framework;
- whereby said existing escalator system is modernized by including new first, second and incline modules within an existing truss framework.
A kit for modernizing an escalator system, comprising:
- a first module including a drive station;
- a second module including a reversing station;
- a plurality of incline modules each of said incline modules including two upstanding elements and a horizontal element joining said upstanding elements with said horizontal element being attached to a cross member of a truss framework of an existing escalator;
- wherein said first module, said second module and said plurality of incline modules fit within said truss framework.
