Abstract: A power transmission system for a people mover includes a transmission housing, a first motor having a motor shaft, an output gear located inside the transmission housing, and a plurality of gears located inside the transmission housing. The plurality of gears includes an output gear located inside the transmission housing, and first and second reduction gears cooperating to drive the output gear. At least one of the first and second reduction gears has an input/output shaft extending outside the transmission housing. The system also includes an external reduction stage located outside the transmission housing and driven by the first motor shaft to rotate the input/output shaft.

Abstract: A handrail drive apparatus is provided comprising a first drive wheel assembly configured to drive a handrail and comprising a planetary gear train arranged to be driven by a first driving member. The handrail drive apparatus further comprises a second drive wheel assembly configured to drive the handrail, the second drive wheel assembly being coupled to the planetary gear train of the first handrail drive wheel assembly by a second driving member. The planetary gear train of the first handrail drive wheel assembly is configured to divide a torque imparted by the first driving member between the first and second drive wheel assemblies.

Abstract: A braking apparatus and method for an escalator or moving walkway are provided. The braking apparatus may include a braking element, a linearly controllable solenoid assembly, a biasing mechanism, and a control device. The braking element may be adapted to engage a brake drum or brake disk on a drive shaft of the escalator or moving walkway. The linearly controllable solenoid assembly may include a brake coil and an elongated member. The elongated member may be moveable linearly along an axis and the braking element may be coupled to the elongated member. The biasing mechanism may be arranged to bias the elongated member in a first direction along the axis to increase a torque applied to the drive shaft by the braking element.

Abstract: A braking system for an escalator having multiple rates of deceleration. When electrical protective devices (EPD) indicate that the escalator should be stopped, the main controller makes a determination as to whether the maximum rate of deceleration should be applied or the lower rate of deceleration. The brake is then controlled according to this determination to prevent a sudden stopping of the escalator when it is not necessary. The EPDs may be divided into two or more groups for different rates of deceleration. A provision may be made for multiple signals at once. If the main controller fails to provide a deceleration rate, the braking controller automatically defaults to the maximum rate. This system may also be used with moving walkways or other conveyors.

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.
