- 针对西气东输的源头工程——克拉2气田第二处理厂的4座质量为68.5t、高度为13.832m的脱水吸收塔吊装技术难题,结合施工现场的实际情况,经过对各种吊装方案进行经济技术对比分析和可行性研究,选择了采用偏心平衡杆对吊车荷载进行合理分配的新方法,在缺少大型吊车的情况下,充分利用施工现场巳有吊车资源,用两台起重能力相差悬殊的吊车合吊脱水吸收塔获得成功,证明这是一种快速、经济而又符合现场施工实际情况的大型塔类设备吊装方案。
In the headstream project of West to East Gas Pipeline, i.e. the Second Treatment Plant of Kela Second Gas Field, the hoisting operation of 4 dehydration-absorption towers with a mass 68.5 t and a height 13.832 m each was a difficult task. Based on economic and technical comparative analyses and feasibility study as well as field construction condition investigation, a new approach using an eccentric balanced beam to rationally distribute crane loads was adopted. In the case of lacking heavy cranes, the available cranes in-situ were fully utilized, and two cranes whose hoisting capacities are great different were utilized together to hoist the dehydration-absorption towers. The successful operation shows that this method is fast, economical and practical for heavy hoisting operation.2009,1(1): 56-57 收稿日期：2008-4-21分类号：TE94作者简介：朱钢坚（1963-）, 男, 广东化州人, 工程师,1984 年毕业于广东石油学校, 主要从事石油化工设备的吊装施工工作。参考文献：
