近几年来,我们在一些小型电厂和工矿企业的锅炉安装中,使用带鹅头的桅杆起重机代替门式起重机或塔式起重机,取得了一定的经济效益。实践证明,用这种方法吊装35～130t/h时锅炉,简单易行,安全可靠,尤其适用于缺少大型起重机械的小型安装队伍。带鹅头的桅杆吊一般由桅杆、鹅头、底座、起升滑车组、变幅滑车组、鹅头平衡滑车组、旋转牵引滑车组组成。当主厂房框架及房 In recent years, we have used some gantry cranes with goose heads instead of gantry cranes or tower cranes in the boiler installation of some small power plants and industrial and mining enterprises, and achieved certain economic benefits. Practice has proved that using this method when lifting 35 ~ 130t / h when the boiler, simple, safe and reliable, especially for the lack of large-scale lifting machinery, small installation team. The mast with goose head is generally composed of a mast, a goose head, a base, a hoist block, a variable block group, a goose head balance block, and a rotary traction block.
