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.

Claim (Index 7):
A tension device for a drive chain of an escalator, wherein the drive chain is mounted and rotated around a driving wheel and a driven wheel, comprising\n a pair of pressing blocks, each of which is provided on one of outer sides of portions of the drive chain between the driving wheel and the driven wheel respectively, wherein the pressing blocks apply pressures to the portions so as to move them close to each other.
