In an escalator or travelator configured to travel in two directions and including a step or pallet belt returned in first and second return portions facing away from each other, a monitoring device and method for detecting steps or pallets of the step or pallet belt is provided. The device includes a first detector configured to detect the steps or pallets in one of the directions of travel, a second detector configured to detect the steps or pallets in the other direction of travel, and an electronic analyzer/controller functionally coupled with each of the first and second detectors. The electronic analyzer/controller is configured to receive and compare signals from the first and second detectors for the two directions of travel and derive therefrom a signal for halting the escalator or travelator. When the signals from at least one of the first and second detectors indicates a missing step or pallet within the step or pallet belt, the electronic analyzer/controller outputs the derived signal to halt a drive of the escalator or travelator.
