Description
Technical field [0001] The present invention belongs to the technical field of road bridges, and is specifically a hoisting device for road bridges. Background technique [0002] Road bridges, generally consisting of roadbed, road surface, bridge, tunnel engineering and transportation engineering facilities, etc., road surfaces are usually composed of road flood body, road shoulder, edge stone stone and central separation belt, including road floods can be divided into driving The road, the sidewalk and the latter belt, the road field can be divided into surface layers, base layer, pad layer or joint layer, etc. according to the structure hierarchy. [0003] At present, the existing road bridge is hoisted with a wire rope. In the process of hoisting, it is easy to cause shake, which is inconvenient to the operation, and there is a certain risk. Inventive content [0004] It is an object of the present invention to provide a hoisting device for a road bridge to solve the problem ...
