Abstract
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.
