The invention discloses a foldable tower cap of a small tower crane. The foldable tower cap comprises a tower cap body, a balance arm, a rotary disc and a tower body, wherein the rotary disc is installed at the top of the tower body, the balance arm is hinged to one side of the rotary disc, the tower cap body is installed above the rotary disc, the tower cap body is hinged to one side of the rotary disc through a hinge assembly, the hinge assembly is located on the same side where the balance arm is hinged to the rotary disc, fixing components are arranged at the four corners of the bottom ofthe tower cap body, four fixing bases are arranged at the corresponding positions of the top of the rotary disc correspondingly, and locking of the tower cap body and the rotary disc is achieved through locking of the fixing components and the fixing bases. The foldable tower cap has the beneficial effects that flexible and reliable connection is provided for self-mounting and self-dismounting ofthe tower cap body, and extra auxiliary hoisting equipment is not needed for mounting and dismounting; and due to the fact that rotary folding can be achieved, self-mounting and self-dismounting are achieved, the mounting and dismounting workloads of mounting, dismounting and transporting working conditions are reduced to the maximum extent, conversion of the mounting, dismounting and transportingworking conditions becomes faster, and the transporting cost is saved.

    一种小型塔式起重机械可折叠式塔帽,包括塔帽、平衡臂、转盘和塔身,所述转盘安装在塔身的顶部,所述平衡臂铰接于转盘一侧,所述塔帽安装在转盘上方,所述塔帽与转盘一侧通过铰接组件铰接,铰接组件位于平衡臂与转盘铰接的同一侧,所述塔帽底部四个角落分别设有固定部件,所述转盘顶部相应位置分别设有四个固定座,通过固定部件与固定座的锁定实现塔帽与转盘的锁定。有益效果:本发明为塔帽的自安装、拆卸提供了灵活可靠的连接,不再需要额外辅助起重设备进行安装、拆卸;由于能够旋转折叠,实现自安装拆卸,最大限度地减少了安装、拆卸及运输工况的安装及拆卸工作量,也使安装、拆卸及运输工况的转换变得更快捷,节省了运输成本。
