The invention provides a novel portal traveling crane capable of being suitable for the occasions where construction windows are dwarf and narrow and platforms are arranged outside the windows. The novel portal traveling crane comprises a traveling rail, a portal frame, movable set forceps, an elevator, a vertical top pressing rod and a transversely-moving machine. The novel portal traveling craneis characterized in that the traveling rail is a rectangular iron frame formed by welding two steel channels with opposite notches, the front end of the traveling rail is sealed, a fixed pulley is arranged at the front end, the rear end of the traveling rail is not sealed, a hoop is arranged on a flying shore at the rear end, the movable suit forceps are arranged on the portal frame, the front portion of the traveling rail is hung on the portal frame through a jaw, wheels are arranged on an elevator base and enter sliding ways from the rear end of the traveling rail, the upper portion of thevertical top pressing rod and the hoop at the rear end of the traveling rail are combined, the traveling rail is in a horizontal state, the transversely-moving machine is arranged at the rear end of the traveling rail, the free ends of two steel wires of the transversely-moving machine are oppositely wound around two coaxial coiling blocks, one ends of the two steel wires are directly combined with the rear portion of the elevator, and the other ends of the two steel wires are wound around the fixed pulley at the front end of the traveling rail and then fixed to the middle of the front end ofthe elevator. The novel portal traveling crane has the beneficial effects of being simple in structure, convenient to use and high in adaptability.
