Abstract
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 (FS1, FS2) 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.

People conveyor (2) configured for conveying passengers by at least one conveyance band (8) travelling along a closed loop and comprising:
- 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 (FS1, FS2) 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.
Method of determining the power which is necessary for driving at least one handrail element (6) of a people conveyor (2), wherein the method includes:
- driving the at least one handrail element (6);
- detecting a force (FS1, FS2) which is exerted by the at least one handrail element (6) in a direction oriented in a direction transverse, in particular orthogonal to the direction of movement of the at least one handrail element (6);
- and
- calculating the driving power (Pup, Pdown) which is necessary for driving the at least one handrail element (6) from the detected force (FS1, FS2).
