Abstract

This invention relates to the field of bridge construction technology, and discloses a construction equipment and method for installing suspenders on a basket arch bridge. Since the working platform is connected to a cable crane via a hoisting wire rope, it can be moved to a certain height directly below the suspender installation area using the cable crane without interfering with the arch ribs of the bridge. Because the suspender is mounted on the moving device via a clamping device, it moves to the same height as the working platform. It is only necessary to ensure that the length above the fixed end of the suspender matches the height difference between the working platform and the suspender's installation area on the arch rib. Then, the angle of the suspender's top end is adjusted using an inclination adjustment device to match the inclination angle of the suspender installation point, thereby achieving rapid suspender installation. This not only reduces the need for temporary working platforms at the suspender location, lowering the safety risks of personnel climbing up and down temporary platforms, but also avoids frequent lateral movements of the cable crane, resulting in high construction efficiency.
