摘要：
A curvature-adjustable handrail length compensation device for an escalator or a moving walkway is provided. The device comprises a frame, handrail support mounted along a length of the frame, and springs mounted to the frame to elastically support the handrail support. Each handrail support includes a supporting rod movably mounted through the frame, a first supporting roller mounted to an end of the supporting rod to support the handrail, and a stopper formed at the other end of the supporting rod. The spring is provided between the frame and the first supporting roller, and biases the first supporting roller away from the frame.
