Escalator handrails move slightly faster than steps for rider safety

Calibrated forward handrail bias stops passenger arms from dragging backward

Escalator rubber handrails are driven by friction wheels synced to step drive chains. Maintenance standards calibrate handrail belt speeds to run fractionally faster than the moving steps. This forward bias prevents passengers' arms from dragging backward, reducing fall hazards.
