摘要： A plate conveyor includes a conveyor belt that is formed of interconnected segments which are guided on tracks, and a handrail which is guided on a handrail guide. The conveyor belt has a longitudinal extent, and the handrail runs, at least in sections, in the direction of the longitudinal extent along the conveyor belt. The handrail guide has at least one length compensation element. A length (L) of the compensation element, measured in the direction of the longitudinal extent, is adjustable between a maximum length (Lmax) and a minimum length (Lmin).

摘要： There is disclosed a display device making it possible to call effective attention in a use situation where unbalanced passenger load occurs between left and right lanes of a passenger conveyor. This display device includes a first display unit (7A) positioned on the left and a second display unit (7B) positioned on the right toward the passenger conveyor at a boarding (1), a control device (20) to control the first display unit (7A) and the second display unit (7B), and passenger detection (8A, 8B) to detect passengers stepping on the passenger conveyor. The first display unit (7A) and the second display unit (7B) display images representing information to passengers. The passengers pass between the first display unit (7A) and the second display unit (7B) and step on the passenger conveyor. The control device (20) estimates a state of congestion and a state of passengers gathering on only one lane in the passenger conveyor, based on detection signals from the passenger detection means (8A, 8B), and sets an image to be displayed by the first display unit (7A) and an image to be displayed by the second display device (7B) independently, depending on the state of congestion and the state of passengers gathering on only one lane.

摘要： The invention provides a handrail belt tension device for an escalator, the escalator comprising a truss and an annular handrail belt rotatable relative to the truss, wherein the handrail belt tension device comprises: a base plate on which a roller for supporting the handrail belt is provided; a guiding mechanism which is fixed to the truss; and wherein the base plate is connected to the guiding mechanism, and rotatable and translatable relative to the guiding mechanism so as to adjust the handrail belt by the base plate thereby the handrail belt can be in a well tensioned status. The handrail belt tension device ensures that the tension device is installed in a more accurate position, making it easier to adjust the tensioning force of the handrail belt, reducing the time for adjusting the handrail belt, and increasing the service life of the handrail belt.

摘要： An illustrative method of making an elevator load bearing member having at least one elongated tension member at least partially covered by a jacket includes mixing a flame retardant with a polymer material. The flame retardant is selected from a group consisting of (i) a halogen-free melamine based intumescent comprising melamine cyanurate, melamine-phosphate, melamine pyrophosphate or melamine polyphosphate in an amount up to about 20% by weight of the thermoplastic polymer or (ii) a filled polymer having a nanoscale filler chemically bonded to a matrix phase. Applying the mixed flame retardant and polymer material to the tension member forms a jacket of a desired shape.

摘要： A handrail drive for driving a handrail of a person-transporting device has at least one drive device and at least one counterpressure device. The counterpressure device contains at least one loading device and at least two counterpressure rollers, wherein the handrail can be guided between the drive device and the counterpressure device. The counterpressure rollers load the handrail against the drive device by a pressing force caused by the preloading force of the loading device. At least one flexible pulling element is arranged between the at least one counterpressure roller and the loading device, by which flexible pulling element the preloading force of the loading device can be transferred to the at least one counterpressure roller.
