“向阳4号”8吨轮胎—轨道两用起重机(图1),是由北京市建筑工程研究所与北京市第六建筑工程公司二工区组成的三结合小组,在毛主席的革命路线指引下,在总结了“向阳1号”至“向阳3号”轮胎起重机和分析了国内外有关起重机械的基础上,研究试制成功的新型起重机。它能满足一般工业厂房和六层以下的民用住宅建筑工程的施工材料、构件的垂直运输,以及施工现场预制构件的装车卸车和立塔、拆塔等作业的需要。
The “Xiangyang 4” 8-ton tire-rail dual-purpose crane (Fig. 1) is a three-combination group composed of the Beijing Institute of Building Engineering and the second engineering area of Beijing No.6 Construction Engineering Company under the guidance of Chairman Mao’s revolutionary route. , On the basis of summarizing the “Yangyang 1” to “Xiangyang 3” tire cranes and analyzing domestic and foreign cranes, a new type of crane has been successfully developed. It can meet the vertical transportation of construction materials and components of general industrial plants and civil residential buildings below six levels, as well as the requirements for loading and unloading of prefabricated components at the construction site, as well as the requirements for erecting towers and dismantling towers.
