The invention relates to the technical field of crane lifting appliances, and discloses a combined lifting appliance for loading and unloading steel wire rods, which comprises a main cross beam and a main cross beam lifting arm connected with the main cross beam through a main cross beam lifting arm support, and the main cross beam lifting arm comprises a main cross beam vertical arm and a main cross beam horizontal arm; one end of the main cross beam vertical arm is connected with the main cross beam suspension arm support, the other end of the main cross beam vertical arm is connected with the main cross beam horizontal arm through a connecting pin shaft, and a first driving mechanism is arranged on the main cross beam vertical arm; the first driving mechanism can drive the main cross beam horizontal arm to rotate in a vertical plane around the connecting pin shaft so as to realize hoisting and unloading of a steel wire rod, a second driving mechanism is arranged on the main cross beam suspension arm support, and the second driving mechanism drives the main cross beam vertical arm to rotate or stretch out and draw back up and down. The purpose that a crane operator can directly operate the lifting appliance to load and unload steel wire rods is achieved, the working efficiency is improved, and meanwhile electric power waste and safety accidents such as accidental falling in the lifting process are avoided.
本申请涉及起重机吊具技术领域,公开了一种钢材盘圆装卸用组合吊具,包括主横梁以及通过主横梁吊臂支座与主横梁连接的主横梁吊臂,所述主横梁吊臂包括主横梁垂直臂以及主横梁水平臂,主横梁垂直臂的一端与主横梁吊臂支座连接,另一端通过连接销轴与主横梁水平臂连接,主横梁垂直臂上设置有第一驱动机构,所述第一驱动机构能驱动所述主横梁水平臂绕所述连接销轴在竖直平面内转动从而实现钢材盘圆的起吊与卸载,所述主横梁吊臂支座上设置有第二驱动机构,第二驱动机构带动主横梁垂直臂转动或上下伸缩。本申请实现了起重机操作司机可以直接操作该吊具装卸钢材盘圆的目的,提高了工作效率,同时还避免了电力浪费和吊运过程中的意外坠落等安全事故。
