The invention relates to the technical field of cargo transportation of cranes, in particular to a portal crane for cargo transportation, which is used for solving the problem that a portal crane in the prior art cannot have the functions of reducing the loss of a sling and assisting in hoisting cargoes when the sling is snapped at the same time. The device comprises two racks, moving assemblies are arranged at the bottoms of the two racks, a top beam is fixedly installed between the tops of the two racks, a cross beam is fixedly installed between the side faces, close to each other, of the two racks, a hanging plate is fixedly installed between the bottoms of four hanging ropes, and a hanging tool is fixedly installed between the bottoms of a plurality of steel ropes; when the lifting plate transversely moves to convey goods, the lifting plate transversely moves on the balance cable through the walking rollers, on one hand, the length of the steel cable between the lifting plate and the lifting appliance is small, the swing amplitude generated during transverse movement is small, and on the other hand, the lifting plate is limited by the balance cable in the horizontal direction through the walking rollers during transverse movement.
本发明涉及起重机货物运输技术领域,具体为一种用于货物运输的门式起重机,用于解决现有技术中的门式起重机,不能够同时具备减轻吊索损耗,以及吊索绷断时对货物的辅助吊起功能的问题;本发明包括两个机架,两个机架的底部均设置有移动组件,两个机架的顶部之间固定安装有顶梁,两个机架相靠近的侧面之间固定安装有横梁,四个吊索的底部之间固定安装有吊板,多个钢索的底部之间固定安装有吊具;本发明在吊板横移对货物进行输送时,吊板通过行走辊在平衡索上横向移动,一方面吊板与吊具之间的钢索长度较短,横移时产生的摆动幅度较小,另一方面吊板在横移时通过行走辊受到平衡索在水平方向上的限位作用。
