行走式塔式起重机轨道上材料运输桁车施工技术

Construction Technology of Material Transportation Dolly on Mobile Tower Crane Track

以阿布扎比国际机场项目为例,通过对可行走在弧线轨道上的材料运输桁车的研究,介绍行走在大跨度轨道梁上材料运输桁车的结构设计、受力验算,动力系统台车的选择校核以及材料运输桁车通过曲线钢轨的验算等材料转运的施工技术。通过实践证明,该施工技术安全、可行,并具有一定的经济效益。

Mobile tower crane is widely used in large-scale construction. And the important prerequisite of project smoothly is to solve the problem of material transportation from periphery to central area. Aiming at arc track with a large span in this paper,main terminal steel structure of Abu Dhabi International Airport will be taken for example to explain the characteristics of material transportation dolly travelling on arc track,to introduce the structure design of material transportation dolly,stress calculation,the choice of power system and checking,calculation of material transportation dolly through arc track. Practice proves that the construction technology is safe,feasible and has a certain economic benefit.
