[0002] During the prefabrication of box girders, the longitudinal reinforcement of single-span box girders is relatively long. After the reinforcement is transported and transported to the destination, the box girders are manufactured by manual pushing and interlacing operations, which is labor-intensive. At the same time, multiple reinforcements need to be transported and assembled, and more than 5 people are required to lift the reinforcements together. The labor intensity is high, which increases the physical burden of workers and easily leads to fatigue and strain. The environment in the reinforcement factory is complex, and workers will encounter obstacles when carrying reinforcements. Carrying reinforcements in a complex environment may cause accidents such as falls and bruises, especially when encountering higher obstacles, they need to squat and lift, and encounter lower obstacles, which increases the risk of injury.
