[0002] A bridge generally refers to a structure erected over rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. To adapt to the modern rapidly developing transportation industry, bridges are also extended to buildings that are erected across mountain streams, poor geological conditions or to meet other traffic needs to make passage more convenient. A viaduct is a type of modern bridge. After construction, the bridge needs to be maintained regularly. When damage occurs at the bottom of the bridge and needs to be repaired, a vehicle with a ladder is usually used for bottom repair. However, since the viaduct is an important transportation hub, there are some problems with general lifting devices;

[0003] Most existing lifting devices usually operate with slings or cables. However, the corner edges of bridge steel plates are relatively sharp. Therefore, when the slings or cables directly contact them, the friction force is large. Over time, the slings will be severely worn, and even fall off, posing a safety hazard.
