The trolley is simple in design and structure, convenient to operate and free of large labor force. Safety protection is in place, and the risk of high-altitude operation in construction is reduced. The mechanical operation is adopted to obviously improve the construction efficiency, further improve the construction quality and greatly save the construction cost.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
