The invention relates to the technical field of portal cranes, in particular to a portal crane capable of moving in a range. The invention provides a portal crane capable of moving in a range. The portal crane is high in safety. A portal crane capable of moving within a range comprises a support, a first sliding rail, a second sliding rail, a sliding block, a first motor, a reel, a first transmission assembly, a pull rope with a hook and the like. First sliding rails are connected to the upper portions of the two supports, a second sliding rail is slidably connected between the two first sliding rails, a sliding block is slidably connected to the inner side of the second sliding rail, a first motor is installed on the sliding block, a winding wheel is rotatably connected to the left side of the sliding block, and a first transmission assembly is connected between the winding wheel and an output shaft of the first motor. And a pull rope with a hook is wound on the reel. People push the second sliding rail back and forth to enable the pull rope with the hook to move back and forth, then people can hang materials on the pull rope with the hook, and then people can move the second sliding rail back and forth again, so that the effect of convenient back and forth movement is achieved.

    本发明涉及门式起重机技术领域,尤其涉及一种门式可范围移动起重机。本发明提供一种安全性较高的门式可范围移动起重机。一种门式可范围移动起重机,包括有支架、第一滑轨、第二滑轨、滑块、第一电机、绕线轮、第一传动组件和带钩拉绳等;两个支架上部均连接有第一滑轨,两个第一滑轨之间滑动式连接有第二滑轨,第二滑轨内侧滑动式连接有滑块,滑块上安装有第一电机,滑块左侧转动式连接有绕线轮,绕线轮与第一电机的输出轴之间连接有第一传动组件,绕线轮上绕有带钩拉绳。本发明通过人们前后推动第二滑轨,使得带钩拉绳前后移动,随后人们可将物料挂在带钩拉绳上,然后人们可再次前后移动第二滑轨,以此实现了方便前后移动的效果。
