一种专用集装箱吊装倾斜原因及对策研究

Cause of hoisting inclining and countermeasures for a special container

对一种专用集装箱结构、特点进行介绍,对该集装箱吊装使用的专用吊具的结构及工作原理作了简要说明。提出了使用中遇到的问题,即吊装货物质心前后位置有较小变化时会引起箱体吊装时较大的倾斜角度,给使用带来安全隐患,严重时甚至因倾角太大无法吊装。文中对该集装箱及普通集装箱因质心变化引起的吊装倾斜角度进行理论计算,分析了该专用集装箱吊装时倾斜角度偏大原因,提出几种减小吊装倾斜角度的方法,并建议对吊具结构进行改进,介绍了一种减小吊装倾角的吊具改进结构。

The paper briefly introduces the structures and characteristics of a special-purpose container, with concise description of the special sling used for container hoisting, and puts forward certain problems found during use. For exam- ple, minor change of center of gravity of the hoisting cargo will cause large angle of inclination during container hoisting, leading to potential safety hazards, even making it unable to hoist due to too large angle of inclination. The paper introduces theoretic calculation for hoisting inclination angle caused by change of center of gravity for the said container and ordinary container, analyzes the cause of too large inclination angle during hoisting of the special container, puts forward several methods for reducing the inclination angle, gives suggestions of improving the sling structure, and presents an improved sling structure decreasing inclination angle.
