[0047] The aerial work platform can effectively increase the maximum working height and working range without increasing the outrigger span, while also improving environmental adaptability and being able to travel in complex environments such as mountainous areas, hills, and fields.
[0048] In some embodiments, the traveling device 100 is a tire vehicle, a crawler vehicle or other devices that rely on power to travel. The other end of the support arm 400 is provided with a bucket, a breaker hammer or a hydraulic clamp, so that for obstacles on a rough road, the support arm 400 can use the bucket, the breaker hammer or the hydraulic clamp to clear the obstacles, meeting the requirements of traveling and working in mountainous areas, hills, fields and the like.
