Background
The precast beam plays an important role in the construction process of expressways, viaducts and the like in China. In general, after the precast beam is prefabricated, the precast beam is transported to a construction site by a beam transporting vehicle, and other equipment such as a gantry crane, a truck crane and a bridge girder erection machine is used for hoisting and erecting construction. When the prefabricated beam frame facility works, the construction of the bridge abutment of the pier is finished, and if the prefabricated beam is conveyed below the bridge floor, the prefabricated beam generally needs to be lifted above the bridge floor on the side of the bridge route and then translated to the design position of the prefabricated beam and placed. Under some special environmental conditions, the prefabricated beam is erected without a lateral lifting beam space, and then the beam is lifted by adopting a high-low lifting mode under the bridge route, namely, one end of the beam is lifted first to enable the beam to incline, when the horizontal projection distance of the prefabricated beam is smaller than the clear distance between two piers, the prefabricated beam is lifted simultaneously, and when the lower end of the prefabricated beam is higher than a pier stud, the main beam is laid flat, and the subsequent construction is continued.
At present, the hoisting of the precast beam is usually carried out by winding and binding steel wire ropes at two ends of the beam and then hoisting the precast beam by using hoisting equipment.
