Bridge hanging baskets are customized products, each of which holds a product patent certificate. It's actually very simple. For example, the electric hanging basket belongs to the national standard product and has no patent. The patent is non-standard customization and does not belong to the national standard product. Electric hanging basket does not belong to special equipment and is not included in the safety supervision scope of special equipment. So is the bridge basket.

Bridge hanging basket must hold quality system certification, product patent and pass inspection before it can be put into use. The 2-ton electric hoist used in bridge hanging basket belongs to special equipment, and the production qualification and inspection certificate of electric hoist need to be issued before use.
