A handrail belt tension device is provided for an escalator having a truss and an annular handrail belt rotatable relative to the truss. The handrail belt tension device includes: a base plate on which a roller for supporting the handrail belt is provided, and a guiding mechanism which is fixed to the truss. 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.

Abrégé

The present disclosure discloses a tension device for a drive chain of a handrail system of an escalator system, a method and an escalator system including the same. The tension device for the drive chain applies pressures in opposite directions to a drive chain so as to make portions of the drive close to each other to tension the drive chain. The pressures are applied to the drive chain via a weight or a pre-loaded spring. The present disclosure also provides a method for tensioning a drive chain. The present disclosure can eliminate loosening of the drive chain after running several months, eliminate periodic heavy work on site for the escalator system and a drive system comprising the drive chain, and improve quality thereof in a simple, reliable and low cost manner.
