An embedded type updating escalator, combined with an original truss of an original escalator for installation. The embedded type updating escalator includes a truss assembly, as well as stairs, stair guide rails, stair chains, a traction machine, a skirt panel, inner and outer cover plates, a handrail system, and an electrical control system which are combined and mounted with the truss assembly. The truss assembly includes multiple sections. The transverse width of the sections is smaller than the inner transverse width of the original truss, and the multiple sections are embedded into the original truss. The original truss is provided with multiple transverse bars, and the sections avoid the transverse bars when embedded into the original truss.

A handrail belt disinfection machine for escalators includes a base and a rolling device having a first support arm and a second support arm on both sides of the base respectively, and both sides of the rolling device are connected to the first support arm and the second support arm respectively, and the rolling device has a disinfection device and drives the operation of the disinfection device. During the use of this machine with novel structure and clever design, the rolling device is contacted with a handrail belt of an escalator, and the movement of the handrail belt drives the rolling device to rotate and further drive the disinfection device to disinfect the handrail belt. When the escalator is not in use, the disinfection device will stop working, so as to achieve energy saving and environmental protection effects.

A side monitoring device for a passenger transport system is described. The device monitors 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. The device includes a mounting structure, at least one elongate belt, and a force sensor. The mounting structure is configured for the installation of the device in a base plate region of the passenger transport system adjacent to a transport region. A belt is functionally connected to the mounting structure and extends parallel to at least a portion of the traveling path. 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.
