Side monitoring device for a passenger transport system

A side monitoring device for a passenger transport system, wherein the side monitoring device is configured for monitoring a force application upon a base plate of the passenger transport system along a gap formed between a transport band of the passenger transport system and the base plate, and wherein the side monitoring device comprises:

• a mounting structure;
• at least one elongate belt;
• and
• a force sensor;
• wherein the mounting structure is configured for installation of the side monitoring device in a base plate region of the passenger transport system adjacent to a transport region in which multiple tread units of the transport band, which are arranged behind one another and coupled to one another, are displaced along a traveling path during the operation of the passenger transport system,
• wherein the belt is functionally connected to the mounting structure and extends parallel to at least a portion of the traveling path,
• wherein the force sensor is functionally connected to the belt and configured for detecting a force exerted upon the mounting structure by the belt in a direction of displacement extending parallel to the traveling path,
• wherein the side monitoring device further comprises a supporting device, which is stationarily held in the base region after its installation and arranged on a side of the belt lying opposite of the transport region, wherein the supporting device supports the belt against a motion that is directed laterally away from the transport region.
