A rope load detecting device for detecting total rope load in multiple elevator ropes, includes a frame held on the multiple elevator ropes, and a force sensing element. The frame includes a tension beam, a first and second connecting bars, a movable member and a supporting beam, one end of the first and second connecting bars is fixed to the tension beam, the other end is fixed to the supporting beam, one end of the movable member is connected to the tension beam, the other end freely passes the supporting beam. The frame is configured to enable the part of each elevator rope passing through the first and second connecting bars and the movable member of the frame to be bent so that enable the force caused by each loaded elevator rope to act on the force sensing element by means of the movable member of the frame, whereby the total rope load in multiple elevator ropes can be detected by a single force sensing element.
