Background Art

A hanging basket is a common high-altitude work auxiliary equipment during the construction or maintenance of bridges. There are many types of hanging basket equipment used for bridge construction on the market. For example, a bridge construction hanging basket disclosed in Chinese patent CN214497219U and a bridge construction hanging basket disclosed in Chinese patent CN219992238U, etc. During use, the motor can be used to drive the lead screw to rotate and the horizontal position of the hanging basket can be fine-tuned horizontally to facilitate increasing the range of high-altitude work for workers. However, the load-bearing capacity of these hanging baskets depends entirely on the single side of the suspension close to the bridge, and they are prone to sinking during use, increasing equipment loss. At the same time, this single-sided fixed hanging basket is more suitable for workers working on the side of the bridge, and is not suitable for repairing the bottom of the bridge.
