Semi-Portal cranes use a trolley drive of portal on rails situated at two levels- on the floor via wheels or on a rail situated into ground and on crane railway on building construction or on self-supporting pillars. Supporting steel construction (semi-portal) consists of one or two main girders and one or two main pillars.
