Abstract: 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.
