A handrail belt disinfection machine for escalators includes a base and a rolling device having a first support arm and a second support arm on both sides of the base respectively, and both sides of the rolling device are connected to the first support arm and the second support arm respectively, and the rolling device has a disinfection device and drives the operation of the disinfection device. During the use of this machine with novel structure and clever design, the rolling device is contacted with a handrail belt of an escalator, and the movement of the handrail belt drives the rolling device to rotate and further drive the disinfection device to disinfect the handrail belt. When the escalator is not in use, the disinfection device will stop working, so as to achieve energy saving and environmental protection effects.

A control device adapted to be connected to a conveyor system having a drive motor, a motor control unit which provides a motor control signal to the drive motor and a motor speed sensor adapted to output a motor speed signal to the motor control unit. The control device comprises: a motor speed alteration unit adapted to intercept the motor control signal and to provide a modified motor control signal to the drive motor so as to cause the motor speed to increase or decrease by a speed change value from a first motor operating speed to a target motor operating speed; and a feedback unit adapted to intercept the motor speed signal and to provide a scaled motor speed signal to the motor control unit based on the intercepted motor speed signal, the scaled motor speed signal indicating to the motor control unit that the motor speed has not been increased or decreased from the first motor operating speed by the speed change value.

A system for braking an escalator or moving walkway includes a handrail and passenger support in registration with one another so as to move together. A braking tensioner selectively increases tension in the handrail during operation. The increased tension serves to frictionally brake the handrail and hence the passenger support. The braking tensioner may be located in any of various locations depending upon system design, and may be driven in any suitable manner, e.g., hydraulically, electrically, electromagnetically, and so on. Frictional wear on the handrail is reduced by the fact that the described braking system spreads the frictional load over a large area of the handrail, e.g., the many locations where the handrail contacts the underlying support throughout its length.
