ESCALATOR SUPPORT STRUCTURE

摘要

A support structure for an escalator includes a bottom landing, a top landing, and a rise that interconnects the bottom and top landings. An improved truss design comprised of steel modules that are stamped or bent is used to form the rise, the top landing, and the bottom landing. The modules have closed sides, which increases the strength and stiffness of the truss while also providing the enclosure for internal escalator components. The modules are either formed as a single piece or formed from multiple pieces that are welded or fastened together. The modules are then secured to each other to form the rise, the top landing, and the bottom landing.
