The present disclosure discloses a tension device (2) for a drive chain (11) of a handrail system (1) of an escalator system, a method and an escalator system including the same. The tension device (2) for the drive chain (11) applies pressures in opposite directions to a drive chain (11) so as to make portions of the drive chain (11) close to each other to tension the drive chain (11). The pressures are applied to the drive chain (11) via a weight (5) or a pre-loaded spring (5'). 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.
