However, the complex rooftop facilities and the changing building design have caused the window cleaning machines to increase in height and weight year by year. If you want to hide them completely, you need lifting equipment with heavier lifting weight and longer lifting distance. Since the structural strength and space of the roof of high-rise buildings are very limited, the vertical lifting platform requires a larger site, while the single scissor lift platform has insufficient lifting distance and cannot completely hide the window cleaning machine.

[0003] At present, the existing problems of the window cleaning machine lifting platform are: the window cleaning machine equipment can be lifted to the maximum extent within a limited range, the structure itself can withstand 5-40 tons of window cleaning machines, and the wheel pressure of the four wheels of the window cleaning machine in the stopped state is quite different, which easily causes the lifting platform to tilt when lifting at a large stroke. Summary of the invention

[0004] In view of the above problems, the utility model provides a heavy-duty double-scissor-type window cleaning machine lifting platform, which can ensure that the lifting platform will not tilt during operation; at the same time, auxiliary power components are added on both sides to reduce the problem of excessive force on the scissor-type twisted shaft in the initial stage of lifting, thereby ensuring the smooth operation of the equipment.
