A device for monitoring the presence. of steps and pallets of an escalator or moving walkway, such that missing steps or pallets are immediately detected, so that the drive will be stopped before the missing or defective part reaches the visible area of the escalator or moving walkway.

Safety device for escalators and moving walkways

The invention relates to a method for regulating the brake(s) of an escalator or moving walkway, independently of the load. According to the invention, actual values are supplied to at least one regulator which contains at least one nominal value, the regulator intermittently performs a comparison between the nominal and actual values and controls at least one brake magnet using these values. The brake magnet or magnets in turn regulate(s) the brake(s) in such a way that a predeterminable linear braking deceleration can be achieved, whereby nominal values, in particular, in the form of several temporary deceleration values, are stored in the regulator in nominal value fields or nominal zones.

Method for regulating the brake(s) of an escalator or a moving walkway

The invention relates to a method for load-independently braking the step or pallet belt of an escalator or a moving walkway. According to said method, the activation of at least one safety element triggers at least one frequency converter in such a way as to activate a time-dependent braking ramp, said frequency converter interacting with the drive motor. The braking ramp then slows down the step or pallet belt to 0 m/s with essentially constant deceleration.

Braking device and method of braking moving pavements respectively escalators

The invention relates to a device for monitoring functional units on escalators and moving walkways, comprising several processors which monitor predetermined parameters of a particular functional unit independently of each other. The processors are connected to devices for immediately shutting down the escalator or moving walkway and interact with at least one other processor which is provided for controlling and/or diagnosing functions which are not relevant to safety.
