The invention discloses a stacking portal and an engineering machine. The stacking portal frame comprises an inner portal frame and an outer portal frame, an outer stand column of the outer portal frame is arranged outside an inner stand column of the inner portal frame in a sleeving mode, and the outer stand column and the inner stand column are both made of seamless steel pipes. According to the stacking portal frame, the inner portal frame and the outer portal frame are made of seamless steel pipes, so that the portal frame structure can be simplified, the manufacturing cost can be reduced, the portal frame strength can be improved, rollers are omitted, and the situation that the operation efficiency is affected due to roller damage is avoided. 本发明公开了一种堆高门架和工程机械。该堆高门架包括内门架和外门架，外门架的外立柱套设在内门架的内立柱外，并且，外立柱和内立柱均由无缝钢管制作而成。本发明提供的堆高门架中，由于采用无缝钢管制得内外门架，从而能够简化门架结构，降低制作成本，并且能够提高门架强度、取消滚轮，避免滚轮损坏影响作业效率。
