The invention discloses a chassis frame and an auto-crane used for optimizing the structure of an existing chassis frame, and relates to the field of engineering machinery. The chassis frame comprises a first box type structure, a second box type structure and a third box type structure which are sequentially connected in a width direction of the chassis frame, and the first box type structure and the second box type structure are different in section shape; the first box type structure is used for deploying a driving shaft and an oil pump, a driving shaft and a thrust rod are arranged below the second box type structure, and the chassis frame is in an asymmetric structure in a width direction. By adopting the above technical scheme, if the chassis frame is locally made into the asymmetric structure, the space for arranging the oil pump and the driving shaft is large, and another side space is small, therefore, the arrangement requirements of the system can be met, the weight of the chassis frame can be maximally controlled, and the structure of the chassis frame can be optimized.
