  • Patent number: 10112661
    Abstract: A track hitching structure is for a wheeled crane and the wheeled crane, and includes a vehicle frame and a connecting cross beam. The first end of the connecting cross beam is connected with a track. The second end of the connecting cross beam is connected with the vehicle frame. The second end of the connecting cross beam is higher than the first end of the connecting cross beam. The vehicle frame is connected with the track by the connecting cross beam with one high end and one low end, so the long-distance force transfer from the track to the race of the vehicle frame can be handled, then the shortcomings of tedious structure, large size, large weight and the like of the connecting device caused by a horizontal connecting cross beam are avoided, and the reliability and the working performance of the entire crane are improved.
