The invention discloses a stacking portal and an engineering machine. The stacking portal frame comprises an inner portal frame, an outer portal frame and a lifting appliance, the outer portal frame is arranged outside the inner portal frame in a sleeving mode and is in sliding fit with the inner portal frame, and the outer portal frame can ascend and descend in the vertical direction relative to the inner portal frame; the lifting appliance is in sliding fit with the outer portal frame and can ascend and descend relative to the outer portal frame. In the stacking gantry provided by the invention, the outer gantry is the lifting gantry, so that the structure of the gantry can be simplified, the manufacturing cost can be reduced, and the influence on the working efficiency due to the damage of the rollers can be 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、外门架和吊具,外门架套设在内门架外且与其滑动配合,外门架可相对内门架沿竖直方向升降移动;吊具与外门架滑动配合,可相对外门架升降移动。本发明提供的堆高门架中,外门架为升降门架,能够令门架结构得到简化,从而有利于降低制造成本,而且能够避免滚轮损坏影响作业效率。
