目前我国的石油、天然气管道输送工程开始与国际接轨,向长距离、大管道方向发展。为提高铺管的效率,各种大、中型管道施工专用设备也纷纷进入管道施工领域,其中最具有代表性的产品就是吊管机。三一重工股份有限公司正是在这种市场需求条件下,经过近一年的努力,成功开发出国内第一台全液压吊管机——DGQ40全液压吊管机。该机是在全液压履带底盘基础上开发的,主要由底盘和工作装置两大部分构成。
At present, China’s oil and gas pipeline project started with the international standards, to the long-distance, large pipe direction. To improve the efficiency of pipe laying, a variety of large and medium-sized pipeline construction equipment have also entered the field of pipeline construction, one of the most representative product is pipelayer. Sany Heavy Industry Co., Ltd. is precisely under such market conditions, after nearly a year of hard work, successfully developed the first full hydraulic pipelayer - DGQ40 full hydraulic pipelayer.
