Abstract: An automatic handrail tensioning system and a method for adjusting the tension degree of a handrail, and belongs to the technical field of escalators. The automatic handrail tensioning system of the present invention comprises: a sensor for detecting information that can reflect a tension degree of the handrail; a controller for determining the tension degree information of the handrail according to the information detected by the sensor, and generating a corresponding control instruction for adjusting the tension degree of the handrail based on the tension degree information; and an actuator for driving a tensioning device to adjust the tension degree of the handrail based on the control instruction.
