The invention relates to the technical field of hoisting equipment, and discloses a portal crane. A main beam, a trolley walking mechanism and a cart walking mechanism connected with the main beam areincluded. The trolley walking mechanism comprises a trolley, a trolley guide rail transversely arranged on the main beam and two winch assemblies symmetrically arranged on the two sides of the main beam. The trolley is used for driving the two winch assemblies to move in the length direction of the trolley guide rail, and the two winch assemblies are used for driving a clamp to do the lifting motion. According to the provided portal crane, the winch assemblies are arranged on the two sides of the main beam, the height of the main beam is utilized, and it is favorable for lowering the warehouse design requirement and increasing the stacking height; and the production efficiency is high.

    本发明涉及起重设备技术领域,公开了一种门式起重机,包括:主梁、小车行走机构以及与所述主梁相连的大车行走机构;所述小车行走机构包括小车、横置于所述主梁上的小车导轨以及对称布设于所述主梁的两侧的两组卷扬组件,所述小车用于驱动两组所述卷扬组件沿所述小车导轨的长度方向运动,两组所述卷扬组件用于驱动夹具升降运动。本发明提供的门式起重机,把卷扬组件布置在主梁的两侧,利用了主梁高度,对降低库房的设计要求和提高码垛高度十分有利;生产效率较高。
