In this paper, a comparative dynamic analysis of the portal cranes of type H and X is described. The difference of the considered cranes arises from the difference of their portals. These two types of portals have the same main geometric measurements. They differ only at the medium level in the horizontal plane. The first type of the portal on the middle level has an H-frame, while the second type has an X-frame. In this paper, dynamic parameters of the two portals have been compared. Estimation has been done to find which of the two types of portals has more favourable dynamic stability for overturn.
