In the recent summer, there are more and more rains, and more and more natural disasters occur in heavy rains. Most of the electric hoist climbing frames are used in the construction industry. The heavy rain period also has a relatively large impact on the construction manufacturing industry. Many projects are not allowed Not being forced to stop work, a small part of the site is still under construction in the rain, and is also using electric hoist for engineering operations, which not only does not speed up the construction progress, but also counterproductive. Because there are many ingredients in the rain water, which are all corrosive, the electric hoist of the climbing frame cannot avoid contact with rainwater when it works on rainy days. When the rainwater is exposed to the electric hoist of the climbing frame, it is very easy to cause the machine to rust and malfunction. If construction is necessary, Under the circumstances, it is necessary to cover the electric hoist with a rain cover or build a rain shed, so as to minimize the damage of the rain to the electric hoist. Under bad weather, it is best to avoid engineering operations. Climbing frame electric hoist work under rain and water for a long time will greatly shorten its life time.
