Beschreibung
Zusammenfassung:	The invention discloses a pull type engineering machinery chassis which comprises a frame, a front supporting leg, a middle supporting leg, a rear supporting leg, an upper fixing lock, a lower fixing lock, a towing hook, a lower guide rail and the like. The front supporting leg, the middle supporting leg and the rear supporting leg are all installed on the frame in a telescopic and retractable mode, the middle supporting leg and the front supporting leg can achieve switching of a supporting mode and a storage mode, and the rear supporting leg is further provided with wheels and can achieve switching of a walking mode, a supporting mode and a storage mode. When the supporting legs are lifted up, traveling of the vehicle is not affected, the supporting legs can support the vehicle when supporting the ground, and the vehicle frame is used for bearing different types of engineering uploads. The device can realize two functions of supporting and transportation, has multiple transportation modes, can realize conven
