Summary:The invention discloses an escalator with a handrail belt excessive extension monitoring device. The escalator comprises a handrail belt, a fixed guide device, a handrail belt tensioning device and a displacement sensor. The fixed guide device comprises a fixed frame and a guide chute formed the fixed frame, and the fixed frame is connected with a metal truss of the escalator. The handrail belt tensioning device comprises an arc-shaped roller set used for supporting and tensioning a handrail belt and a pull rod adjusting device capable of adjusting the horizontal height of the arc-shaped roller set. And the displacement sensor monitors the moving distance of the arc-shaped roller set in real time and outputs a corresponding displacement value signal to a microcomputer main controller of the escalator. According to the escalator with the handrail belt excessive extension monitoring device, the extension amount of the handrail belt can be measured in real time, the service life of the handrail belt and even the
