Automobile crane is a type of crane mounted on a regular or specially designed truck chassis, with separate driver's cabin and crane operator's cabin. The chassis performance of an automobile crane is equivalent to that of a cargo truck with the same total weight, meeting the technical requirements for road vehicles, allowing it to travel smoothly on various types of roads. This type of crane typically has two control cabins, one for operating from the upper part of the crane and the other for operating from the lower part. Stabilizing outriggers are extended during operation to ensure stability.
