The invention discloses an engineering machinery leveling chassis, engineering machinery and a crawler-type tower crane, which comprise a landing leg unit loading assembly, a leveling telescopic cylinder landing leg unit (2) and a traveling mechanism, wherein at least four corner parts at the bottom of the landing leg unit loading assembly are correspondingly supported and connected to the upper parts of the corresponding leveling telescopic cylinder landing leg units (2) through spherical hinges (4), and the lower parts of the leveling telescopic cylinder landing leg units (2) are respectively connected to the traveling mechanism. Aiming at the application occasion of large or ultra-large engineering machinery, such as a movable tower crane, the leveling telescopic cylinder supporting leg units and the traveling mechanism which are arranged on the upper part and the lower part are originally connected through the spherical hinges, so that each leveling telescopic cylinder supporting leg unit can be independently leveled, and the leveling performance is good.

    本发明公开了一种工程机械调平底盘、工程机械和履带式塔机,其包括支腿单元上装总成、调平伸缩缸支腿单元(2)以及行走机构,其中所述支腿单元上装总成底部的至少四个边角部位通过球铰(4)对应支承连接到相应的所述调平伸缩缸支腿单元(2)的上部,且各个所述调平伸缩缸支腿单元(2)的下部分别连接到所述行走机构上。本发明针对大型或超大型工程机械,例如移动式塔机的应用场合,独创性地通过球铰连接上装与下部的调平伸缩缸支腿单元和行走机构,使得各个调平伸缩缸支腿单元能够独立地进行调平,并且调平性能良好。
