A safety monitoring device monitoring safety-related states in a passenger conveyor system has first and second double contact relays each controlled by a control voltage to switch first and second normally open contacts and a feedback contact synchronously between an open and closed relay states. First and second controllers each determine properties of the system correlated with safety-related states and in dependence generate the control voltages. The controllers and two double contact relays form first and second safety monitoring switch arrangements for monitoring first and second safety-related states and correspondingly switch first and second switching states within a safety monitoring chain of the system. The first arrangement includes the first contact of the first connected in series with the first contact of the second relay. The second arrangement includes the second contact of the first relay connected in parallel with the second contact of the second relay.

A monitoring device for passenger transport systems, which systems are designed as elevators, escalators or moving walkways, includes at least one detecting device used to detect an external actuation of an equipment of the passenger transport system, a control device and at least one energy store for storing electrical energy. The energy store is kept in a charged state. The energy store is put into a discharged state when the detecting device detects the external activation of the equipment.

An electromechanical brake comprising mobile induced elements or sectors or frames (2), the number of mobile induced elements (2) or sectors being at least three, where one of the sectors acts faster than the rest, and where one of the sectors acts in a delayed manner with respect to the rest of the sectors in the case of an emergency, said time-delayed actuation being achieved by means of the antiparallel arrangement of a diode (6) on the coil (5) associated with said sector. Smooth and progressive stop is thus achieved in the case of an emergency.

This invention relates to a braking device (10) for a passenger conveyor comprising at least one movable part (12). The braking device (10) comprises a braking element (18) having a braking portion (34) engageable with the movable part (12) of the passenger conveyor. The braking element (18) is movable in a first direction into a position in which the braking portion (34) engages with said movable part (12) of the passenger conveyor. The braking element (18), in a state in which the braking portion (34) engages with the movable part (12) of the passenger conveyor, is movable in a second direction from a position of initial engagement of the braking portion (34) into a braking position of the braking element (18). The movement in the second direction is driven by movement of the movable part (12) of the passenger conveyor.
