近年来经济的不断提高,促进了城市的发展,交通业也随之发展壮大起来,交通成为个城市间相互沟通的纽带,公路、铁路的桥梁工程越来越多而且规模也越来越大,大多数的公路、铁路桥梁基本都具备大跨度、多跨长距离的特点。科技水平的不断提高,使得桥梁工程的施工技术水平得到了很大的提高和进步。在交通工程设计中,对于大跨度的钢制箱桥的工程施工当中离不开龙门吊,龙门吊是是安装施工过程中比不可少的机械设备,龙门吊针对于大跨度的钢箱梁设计科学,安装施工方便,程序简单效率高,能够有效的解决桥梁工程施工的进度和质量方面高要求的问题,能为项目工程创造出巨大的经济效益和社会效益。
In recent years, the continuous improvement of economy has promoted the development of the city. As a result, the transportation industry has also developed and expanded. Traffic has become a link between cities. As the number of bridges and bridges on the roads and railways is increasing and the scale is getting larger and larger, Most of the roads, railroad bridges are basically equipped with large-span, multi-span long distance characteristics. Constantly improve the level of science and technology, making bridge engineering construction technology has been greatly improved and progress. In the traffic engineering design, for the long span of the steel box bridge construction can not be separated from the gantry crane, gantry crane is the construction of the necessary mechanical equipment, gantry crane for large-span steel box girder design science, installation The construction is convenient, the procedure is simple and efficient, which can effectively solve the problems of high requirements in the progress and quality of bridge construction, and can create huge economic and social benefits for the project.
