Description

Technical Field

[0001] The utility model relates to the technical field, and more specifically, to a mobile assembly work platform for an aircraft cargo hold. Background Art

[0002] The aircraft cargo hold refers to the area on the aircraft used to load cargo and luggage. Generally speaking, the cargo hold is divided into two types: the main cargo hold and the auxiliary cargo hold. The main cargo hold is located below the passenger cabin and is usually used to load large cargo and luggage, while the auxiliary cargo hold is located above the passenger cabin and is usually used to load smaller items and luggage. The size and capacity of the cargo hold depends on the model and design of the aircraft. A work platform is required during the assembly of the aircraft cargo hold. Traditional work platforms are generally welded from steel pipes. The work ladder is relatively bulky and has poor mobility, which is time-consuming and labor-intensive to use. In addition, the work ladder can only cover a very small area, and the operator needs to move the work ladder manually, resulting in multiple up and down movements, which reduces assembly efficiency.
