A truck crane is a type of crane mounted on a regular truck chassis or a specially designed truck chassis. The driving cab and the crane control cab are set separately. The chassis performance of the truck crane is equivalent to that of a cargo truck with the same total weight, meeting the technical requirements for road vehicles, and thus, it can travel smoothly on all types of roads. This type of crane typically has two control cabins, one for driving and one for operating, and it is necessary to extend the outriggers to ensure stability during operation.
