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 11):
The tension device according to  claim 8 , wherein\n a cable wire fastener is provided on one connecting rod, a guiding and supporting member for a cable wire is provided on the other connecting rod, one end of the cable wire is fastened to the one connecting rod by the cable wire fastener, guided and supported by the guiding and supporting member for the cable wire on the other connecting rod, and the other end of the cable wire is connected to the weight, and wherein the weight applies pressures to the connecting rods through the cable wire fastener and the guiding and supporting member for the cable wire, at least one of the connecting rods rotate about respective hinges close to each other, and the pressing blocks apply pressures to the drive chain to move the portions of the drive chain between the driving wheel and the driven wheel close to each other.
