Apparatus, system, and method for controlling a handrail of an escalator
A handrail drive inverter for an escalator can include a memory configured to store instructions, a processor coupled to the memory, an input configured to receive a main speed control signal that corresponds to the speed of a main drive motor of the escalator, and an output configured to provide a handrail speed control signal for a handrail drive motor based on the instructions in the memory. The processor is configured to calculate a torque output of the handrail drive motor and determine the handrail speed control signal as a function of the torque output and a feedback of the handrail speed control signal constrained by at least one of an upper limit and a lower limit, the upper limit and the lower limit being determined from the main speed control signal.

HANDRAIL DRIVE FOR AN ESCALATOR OR A MOVING WALKWAY
The invention relates to a handrail drive 2 for driving a handrail 3 of a transportation system, which has at least one drive device 4 and at least one counterpressure device 5. The counterpressure device 5 contains at least one taughtening spring 42 and at least one counterpressure-roller 32 to 39. Between the drive device 4 and the at-least one counterpressure-roller 32 to 39, the handrail 3 is arranged approximately in a linear travel direction 29, 30 and, with a press-on force 45 which is caused by the taughtening spring 42, is pressed by the at-least one counterpressure-roller 32 to 39 against the drive device 4. The handrail drive 2 has a mechanical redirection device 80, by means of which the spring-force 44 of the taughtening spring 42 can be redirected into the press-on force 45 of the at-least one counterpressure-roller 32 to 39.
