Description

Technical Field

[0001] The invention relates to a mechanical hanging basket, in particular to a mechanical hanging basket for building bridge construction. Background Art

[0002] The hanging basket is a construction tool for high-altitude operations in construction projects, used for curtain wall installation and exterior wall cleaning. The hanging basket is a new type of high-altitude operation equipment that can replace traditional scaffolding, reduce labor intensity, improve work efficiency, and can be reused. The use of construction hanging baskets has gradually become a trend and has been widely recognized in high-altitude operations such as exterior wall construction, curtain wall installation, insulation construction, and exterior wall maintenance and cleaning of high-rise and multi-story buildings. It can also be used for operations in large tanks, bridges, dams and other projects. Using this product, scaffolding is unnecessary. The construction cost is reduced, and the construction cost is 28% of the traditional scaffolding, and the work efficiency is greatly improved. The hanging basket is flexible to operate, easy to move, convenient and practical, safe and reliable.

[0003] The existing mechanical hanging basket used in bridge construction generally adopts a lifting wheel and a lifting rope to lift the hanging basket, so as to lower the hanging basket to a specified position. However, the longer the lifting rope is, the more likely it is to shake in bad weather, thereby causing the hanging basket to be unstable, which in turn easily poses a threat to the life safety of construction workers. At the same time, since the general mechanical hanging basket has a simple structure and only relies on a lifting wheel and a lifting rope for lifting, once the lifting wheel and the lifting rope are damaged, the hanging basket is likely to fall directly without the protection of a safety mechanism.
