北京市建筑工程总公司成立40年来,机械装备从无到有,从小到大,有了很大发展,施工机械化水平显著提高,有大吨位塔式、履带式、轮胎、汽车起重机,各种型号打桩机和钻孔机,还有移动、固定式搅拌站配套的移动、固定混凝土泵、搅拌车,以及其他运输车辆、机具、钢筋加工厂,满足了从深基础到高层超高层大型公共设施施工需要。 1 建筑施工垂直运输机械 1.1 塔式起重机的发展 1958年以前,施工垂直运输主要依靠井架和卷扬机加翻转料斗或平板吊笼,还有摇头把杆组成的井架起重机和少量少先吊。1954年设计了红旗Ⅰ型
In the 40 years since the establishment of the Beijing Construction Engineering Corporation, the mechanical equipment has grown from scratch to small, with great development, and the level of construction mechanization has been significantly improved. There are large tonnage towers, crawlers, tires, and truck cranes. Piling and drilling machines, as well as mobile and fixed concrete pumps and mixers for mobile and stationary mixing stations, as well as other transportation vehicles, machine tools and steel processing plants, have met the construction of large-scale public facilities from deep foundations to high-rise super high-rise buildings. need. 1 Construction of vertical transport machinery 1.1 Development of tower cranes Prior to 1958, vertical transport of construction mainly relied on derricks and winches plus turning hoppers or flat cages, as well as derrick cranes consisting of head-shaking bars and a small number of first cranes. 1954 Designed Red Flag Type I
