The invention provides a portal crane. The portal crane comprises a cart mechanism, a door frame mechanism, a supporting leg mechanism suitable for being connected with the cart mechanism and the door frame mechanism, and a hoisting mechanism arranged on the door frame mechanism; the door frame mechanism comprises a cross beam and main beams arranged at the two ends of the cross beam, and the main beams are connected with the supporting leg mechanism; the hoisting mechanism comprises a crown block cart frame and a trolley structure, the crown block cart frame is arranged on the main beams and suitable for moving in the length direction of the main beams, and the trolley structure is arranged on the crown block cart frame and suitable for moving in the length direction of the crown block cart frame; and the two ends of the crown block cart frame extend towards the direction far away from the main beams. The cart frame and the trolley structure are arranged on the portal crane serving as fabricated building erection construction equipment, so that the hoisting range of the portal crane for hoisting heavy objects through the trolley structure is widened, the application range of the portal crane is widened, the erection efficiency of the fabricated building is improved, ad the cost of erecting construction equipment of the fabricated building is reduced.

    本发明提供了一种门式起重机,包括:大车机构、门框机构、适于连接大车机构与门框机构的支腿机构以及设置在门框机构上的起吊机构;门框机构包括横梁和设置在横梁两端的主梁,主梁与支腿机构连接;起吊机构包括天车大车架和小车结构,天车大车架设置在主梁上并适于沿主梁的长度方向移动,小车结构设置在天车大车架上并适于沿天车大车架的长度方向移动;且天车大车架的两端朝向远离主梁的方向延伸。本发明通过在作为装配式建筑架设施工设备的门式起重机上设置天车大车架和小车结构,提升了门式起重机通过小车结构起吊重物的起吊范围,从而提升了门式起重机的适用范围以及装配式建筑的架设效率,且降低了装配式建筑架设施工设备的成本。
