The invention discloses a portal crane adapting to limited top space, and relates to the technical field of cranes. Comprising an end beam and a cart mechanism installed on the end beam, and further comprises a lower trolley, a split type externally-hung upper trolley and a main beam, the lower trolley and the split type externally-hung upper trolley are installed on the main beam, the lower trolley comprises a lower trolley frame and a first lifting winding drum set, and the first lifting winding drum set is installed on the lower trolley frame; the lower side of the first lifting winding drum set is connected with a first lifting hook, split type externally-hung upper trolleys are symmetrically arranged in the axial direction of the main beam, and the split type externally-hung upper trolleys are connected with second lifting hooks. The multi-point type lifting device has the advantages that objects can be lifted in a multi-point mode through the lower trolley and the split type externally-hung upper trolley, the stability in the lifting process can be guaranteed through multi-point type lifting, and due to the fact that the lower trolley and the externally-hung trolley can be controlled separately or synchronously, the lifting efficiency is improved. Shuttling movement of the split type externally-hung upper trolley and the lower trolley can achieve overturning of the hoisted object.
本发明公开了一种适应顶部空间受限的桥门式起重机,涉及起重机的技术领域。包括端梁以及大车机构,大车机构安装于端梁上,还包括下小车,分体式外挂上小车和主梁,下小车,分体式外挂上小车安装于主梁上,下小车包括下小车架和第一起升卷筒组,第一起升卷筒组安装于下小车架上,第一起升卷筒组下侧连接有第一吊钩,沿主梁的轴向方向分别对称设置有分体式外挂上小车,分体式外挂上小车连接有第二吊钩。具有的优点:通过设置的下小车和分体式外挂上小车可以多点式的对物体进行提升,多点式提升能够保证提升过程中的稳定性,由于下小车与外挂式小车可以分别控制,也可以同步控制,分体式外挂上小车与下小车的穿梭移动则可以实现被吊物的翻转。
