Description

Technical Field

[0001] The utility model belongs to the technical field of aerial work, and in particular relates to a crawler spider type aerial work vehicle with high safety. Background Art

[0002] Aerial work platforms are mainly used to clean the facades of high-rise building podiums and roof surfaces of large spaces, and to transport workers and work equipment for maintenance and decoration operations to designated heights for special operations. Aerial work platforms are generally installed on specific automobile chassis or special chassis.

[0003] At present, most of the aerial work platforms above 20 meters in China are mainly vehicle-mounted. This type of aerial work platform places the working device on the chassis of the car and uses the power of the car engine to achieve the lifting and lowering of the working device. Since vehicle-mounted aerial work platforms mostly use wheeled chassis, their passability is poor. In some special work occasions, their use has great limitations, such as indoor gymnasiums, hotels, narrow construction passages and muddy and rugged construction sites, and they cannot be used for indoor work; they can only be used on hardened roads, not soft ground, and the work basket is prone to shaking during high-altitude operations. Under inertia, workers are more likely to experience greater shaking, so the safety is low. Utility Model Content
