The invention belongs to the technical field of engineering machinery equipment, and particularly relates to an engineering machine and a frame thereof, the engineering machine frame comprises a frame middle section and a frame composition section, and the horizontal plane where the highest point of the frame composition section is located is lower than or flush with the horizontal plane where the highest point of the frame middle section is located. The horizontal plane where the lowest point of the frame composition section is located is higher than the horizontal plane where the lowest point of the frame middle section is located. The engineering machinery frame is a main bearing part of the engineering machinery chassis, and the middle section of the frame is a core bearing part of the engineering machinery chassis. According to the vehicle frame, the horizontal plane where the highest point of the vehicle frame middle section is located is higher than or flush with the horizontal plane where the highest point of the vehicle frame composition section is located; the horizontal plane where the lowest point of the frame middle section is located is lower than the horizontal plane where the lowest point of the frame composition section is located, so that the height of the cross section of the frame middle section is increased relative to the frame composition section, the structural strength of the frame middle section is remarkably improved, and the structural strength of the engineering machinery frame is improved.
本申请属于工程机械设备的技术领域,具体地涉及一种工程机械及其车架,该工程机械车架包括车架中段和车架组成段,车架组成段的最高点所在的水平面低于或齐平于车架中段的最高点所在的水平面,车架组成段的最低点所在的水平面高于车架中段的最低点所在的水平面。工程机械车架是工程机械底盘的主要承重部件,车架中段为工程机械底盘的核心承载部件。在本申请中,通过设置车架中段的最高点所在的水平面高于或齐平于车架组成段的最高点所在的水平面,并设置车架中段的最低点所在的水平面低于车架组成段的最低点所在的水平面来使车架中段的横截面高度相对于车架组成段增大,从而使车架中段的结构强度得到显著提升,进而提高工程机械车架的结构强度。
