TECHNICAL FIELD

With the continuous development of construction industry, the performance requirements of building hanging basket are also increasing.
[0003] In the use process of building hanging basket, landing impact and swing in the operation process are two most prominent problems. As for landing impact, the current buffer design of part of hanging basket is relatively simple, and single spring or rubber pad and other basic buffer elements are mostly used. For example, some traditional hanging baskets are only installed with a small amount of spiral spring at the bottom, which often cannot effectively absorb and disperse the impact force. Since the impact force cannot be fully relieved, the equipment in the hanging basket may be damaged, and more seriously, the construction personnel may be physically harmed, which greatly threatens the construction safety.
[0004] At the same time, the swing problem of hanging basket in the operation process also brings many troubles to the construction. On the one hand, in the high-altitude environment, wind force is an important factor that cannot be ignored, and even moderate intensity wind may make the hanging basket swing obviously. On the other hand, the normal operation behaviors such as personnel walking in the hanging basket and material loading and unloading may change the center of gravity of the hanging basket, and further cause swing. The existing anti-swing measures are usually to use rope fixing or simple mechanical limiting structure. Although the rope fixing method can limit the activity range of the hanging basket to a certain extent, it cannot limit and adjust the swing, and the rope may be loose after long-term use, which affects the anti-swing effect.
