[0018] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0019] Example

[0020] See Figures 1 to 6As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0021] The rotatable and foldable ladder in this embodiment includes a rotating mechanism 1, a folding mechanism 2, and a pin mechanism 3. The folding mechanism 2 is rotatably mounted on the rotating mechanism 1, and the pin mechanism 3 is mounted on the sub-beam 4 of the aerial work platform. The rotating mechanism 1 includes a rotating ladder body 11 and a rotating handrail 12. The folding mechanism 2 includes a folding ladder body 21, a folding step 22, and a folding bolt 23. The rotating handrail 12 is fixed on the rotating ladder body 11.

[0022] In this embodiment, the rotating ladder 11 is rotatably mounted on the sub-beam 4 of the aerial work platform vehicle by rotating bolt 13. The upper end of the folding ladder 21 is rotatably mounted on the rotating ladder 11 by folding bolt 23. The folding step 22 is fixed on the folding ladder 21. The lower end of the folding ladder 21 is equipped with a folding sealing plate 24. The upper part of the folding ladder 21 is equipped with a folding pad 25. The folding pad 25 contacts the sub-beam 4 of the aerial work platform vehicle.

[0023] In this embodiment, the pin mechanism 3 cooperates with the rotating ladder 11. The pin mechanism 3 includes a pin body 31, a pin panel 32, and a pin fixing plate 33. The pin panel 32 is fixed on the sub-beam 4 of the aerial work platform vehicle. The pin body 31 is installed on the pin panel 32. The pin fixing plate 33 is fixed on the folding pedal 22. The pin body 31 and the pin fixing plate 33 cooperate.

[0024] Specifically, the rotating ladder body 11 of the ladder is rotatably mounted on the sub-beam 4 of the aerial work platform vehicle via rotating bolts 13, and the folding ladder body 21 is rotatably mounted on the folding ladder body 21 via folding bolts 23. When stored, it is as follows... Figure 1-3As shown, in this state, the folding ladder 21 and the rotating ladder 11 are in a horizontal position. That is to say, at this time, the folding ladder 21 and the rotating ladder 11 can be rotated along the rotating bolt 13 and turned into the inner side of the sub-beam 4 of the aerial work platform. The folding ladder 21 is fixed by inserting the pin body 31 into the pin fixing plate 33. When using the ladder, the pin body 31 can be pulled to disengage the pin body 31 from the pin fixing plate 33. The rotating ladder 11 and the folding ladder 21 can be rotated along the rotating bolt 13. The folding bolt 23 can be used to verify that the folding ladder 21 is rotated. The folding ladder 21 can be lowered so that the folding pad 25 contacts the sub-beam 4 of the aerial work platform.
