GJ956118 带回转塔身的塔式起重机 DE 4221915[专,德]/(Ledergerbar Hang-jurgen…).—1994.1.5.—(1992.7.3);Int,Cl.B 66 C 23/28 发明的目的是简化带非回转塔身的大型塔式起重机的安装。水平机架固定在起重机的支承回转装置上,而水平机架的尾端装有钢丝绳卷扬机。机架上装有带塔身架和平台的头部,平台上装有带吊臂滑轮组和起重钢丝绳滑轮的两脚支柱。吊臂的铰链安置在平台尾部拉杆的下面。安装时,首先借助于起升到接近于垂直位置的吊臂使塔身下部的塔节引入头部的塔身架,然后依次安装所有的其余塔节,再利用缠绕在尾部分支滑轮组上的吊臂钢丝绳将塔身架连同平台一起沿塔身升起,最后再将平台固定在塔身的头部。图
GJ956118 Tower crane with a slewing tower DE 4221915 [special, de] / (Ledergerbar Hang-jurgen ...).-1994.1.5.-(1992.7.3); Int, Cl.B 66 C 23/28 inventions The purpose is to simplify the installation of large tower cranes with non-rotating towers. The horizontal rack is fixed on the supporting swing device of the crane, and the tail end of the horizontal rack is equipped with a wire rope hoist. The frame is equipped with a head with a tower frame and a platform. The platform is equipped with a two-limb column with a boom block and a hoist rope pulley. The boom’s hinge is placed under the platform’s tail pull rod. During installation, the tower section at the lower part of the tower is firstly introduced into the tower frame of the head by means of a boom that is lifted to a near vertical position. Then all the remaining tower sections are installed one after another, and then the crane is wound around the tail branch pulley block. The arm wire rope lifts the tower body together with the platform along the tower body, and finally fixes the platform to the head of the tower body. Figure
