A drive belt (10; 20; 60) for a people conveyor comprises: a load bearing portion (12; 22; 62) extending in a longitudinal direction and having a length extending in the longitudinal direction and a width extending in a width direction; and a plurality of rollers (17; 27; 67) accommodated within the width of the load bearing portion (12; 22; 62). At least a part of the load bearing portion (12; 22; 62) is provided with a drive belt engagement structure (13; 23; 63). The drive belt engagement structure (13; 23; 63) in particular includes teeth (14, 25; 24), grooves (16; 26), and/or openings.

A people conveyor (2), which is configured for conveying passengers by at least one conveyance band (8) travelling along a closed loop, comprises at least one handrail element (6) which is configured for moving parallel to the at least one conveyance band (8) along a travel path forming a closed loop; and at least one force sensor (18a, 18b), which is configured for detecting a force (F.sub.S1, F.sub.S2) exerted by the at least one handrail element (6) in a direction transverse to the direction of movement of the at least one handrail element (6) and for providing a corresponding force signal.

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.
