[0002] With the development of the construction industry, the use of traction construction hoists has become more and more widespread, and construction hoists are only used during the construction process. The shaft dimensions on site vary according to the construction requirements. The difference in shaft dimensions directly affects the size change of the cage top. The existing general cage tops are mostly fixed sizes. During construction work, it is necessary to measure the shaft dimensions on site to customize the cage top of the corresponding size, which will extend the procurement time and indirectly increase the construction time. Moreover, cage tops of specific sizes generally require customization by manufacturers. The production cost of special products is more expensive than general products, which leads to an increase in construction costs.

[0003] In view of this, research and improvement are carried out to provide a retractable cage top for a traction-type construction elevator, aiming to solve the problem of reducing construction costs and improving practical value through this technology. Utility Model Content
