[0002] With the continuous development of social economy, the pressure on traffic is also gradually increasing, which also provides a broad development platform for the development of bridge construction. In the construction of bridge engineering, the erection of main beams in complex environments is the key and difficult point faced in bridge construction. In related technologies, the main beams are generally directly lifted to a high place by a crane for installation. However, affected by the complex wind and wave environment of the special geographical location, especially for main beams with excessive lateral swing amplitude, the hoisting process can easily cause the main beam to be hoisted to collide with the hoisted main beam. This not only increases the difficulty of hoisting the main beam in the middle of the span, but also poses a greater safety and quality risk. At the same time, there is a risk of falling goods during the hoisting process. If the staff are too close, there will be a great safety hazard. Therefore, we have redesigned a bridge main beam hoisting auxiliary device. Utility Model Content

Horizontal sliding adjusters 7 are set on both sides of the front of the lifting lifting plate 6.
