The invention provides an engineering chassis and engineering machinery, comprising: a frame, a front leg mounted on the frame and close to the head end of the frame; the rear supporting leg is mounted at the tail part of the frame; the telescopic assembly is located between the front supporting leg and the rear supporting leg in the vehicle length direction of the vehicle frame and comprises two telescopic supporting legs arranged on the two sides of the vehicle frame in the vehicle width direction of the vehicle frame, the telescopic supporting legs can stretch out and draw back in the vehicle width direction, the supporting point connecting line of the two telescopic supporting legs is a transverse supporting point connecting line, and the supporting point connecting line of the front supporting leg and the rear supporting leg is a longitudinal supporting point connecting line. The transverse fulcrum connecting line is perpendicular to the longitudinal fulcrum connecting line. On the premise that the arrangement of the chassis is more compact, the supporting performance is stronger, the mass of the chassis can be effectively reduced under the same stability performance, so that the mass of the whole engineering machinery is reduced, the performance of a crane is improved, and only one pair of telescopic supporting legs with a telescopic function needs an unfolding space, so that the engineering machinery can adapt to a narrow space.

    本发明提供一种工程底盘及工程机械,包括:车架、前支腿,安装于车架并靠近车架的首端;后支腿,安装于车架的尾部;伸缩组件,沿车架的车长方向位于前支腿和后支腿之间,伸缩组件包括两个沿车架的车宽方向分设于车架两侧的伸缩支腿,伸缩支腿能沿车宽方向伸缩,两个伸缩支腿的支点连线为横向支点连线,前支腿和后的支点连线为纵向支点连线,横向支点连线和纵向支点连线垂直。本发明在底盘布置更紧凑的前提下,支撑性能更加强大,在相同稳定性能下可以有效减轻底盘质量,从而减轻工程机械整机质量,提高起重机性能,且只有一对具有伸缩功能的伸缩支腿需要展开空间,使工程机械能适应狭小空间。
