摘要：本文研究了一种需研究一种能大跨距、两箱同时装填的现场搭接桥吊系统。该系统与传统随车吊的显著区别在于添加前端支腿和迁移体在伸缩臂上运动。该附加有迁移体的伸缩臂称为迁移臂，其设计尤为关键。在这里准备将伸缩臂的伸缩运动与迁移体（带吊具）的迁移运动分开，伸缩臂伸出驱动采用传统方法：由液压缸推动一级臂、通过钢丝绳-滑轮推动二级和三级臂伸出；在伸缩臂前端安装支腿支撑在发射车上构成“桥”，伸缩臂作为桥梁是迁移体运动的导轨，装有吊具座的迁移体有滚轮和调姿装置，在卷扬机作用下作迁移运动和调姿运动，直至成功装填76679

Title For field lap of launch container loading bridge cranes migrate arm design
Abstract This paper studied a need to study a kind of big span, two cases of loading at the same time the scene lap bridge crane system。The system and the traditional lorry-mounted crane is to add the marked differences between the front leg and migration in telescopic arm motion。The additional migration body telescopic jib arm called migration, its design is particularly critical。Here ready to telescopic crane telescopic movement and migration (with sling) migration movement apart, telescopic arm outstretched driven by traditional methods: arm driven by hydraulic cylinder level, through the wire rope pulley to promote the secondary and tertiary arm stretched out;Installed in telescopic arm front leg support "bridge" is made in the launch vehicle, the moving body is telescopic boom as a bridge in the movement of the guide rail, equipped with sling a migration of roller and the position device, in hoist operating migration movement and the posture movement, loading until success
Keywords Large span Two cases of loading at the same time Lap bridge crane system Move the arm hoist
