Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and in particular relates to a high-stability crawler spider crane. Background Art

[0002] Spider crane is a special engineering equipment used for lifting. At present, the driving performance and driving performance of the general automobile chassis aerial work vehicle are excellent, which can facilitate the conversion of the work site.
