A novel bridge crane parallel operation connecting rod installation device comprises a pulley yoke, a bridge crane main beam and a supporting plate, a bottom plate is installed on the side wall of the bridge crane main beam, a first hinge is arranged at the upper end of the bottom plate and hinged to the supporting plate, one end of the supporting plate freely rotates around the first hinge, and a second hinge is installed at the other end of the supporting plate and hinged to a supporting rod. Pulley yokes are arranged on the upper end surfaces of the bridge crane main beam and the supporting plate; and fixed pulleys are arranged in the middles of the pulley yokes. A fixing device is further arranged on the upper end face of the bridge crane main beam, and the fixing device can clamp the connecting rod and enable a plurality of bridge cranes to run in parallel; the installation step of the connecting rod is changed from traditional manual carrying to pulley rolling carrying, a large amount of manpower is sav
