FIELD: transport machine building.
SUBSTANCE: invention relates to a caterpillar coupling structure for a wheeled crane and a wheeled crane. Caterpillar coupling structure comprises a vehicle frame and a connecting transverse beam, the first end of the connecting transverse beam is connected to the caterpillar, the second end of the connecting transverse beam is connected to the vehicle frame and the second end of the connecting transverse beam is located higher than the first end of the connecting transverse beam. Vehicle frame is connected to the caterpillar by a connecting transverse beam with one high end and one low end, so that the force can be transferred a long distance from the track to the recess of the vehicle frame.
EFFECT: higher reliability and efficiency of the entire crane is achieved.
