LTM 1750-9.1拆除大型悬挂脚手架

贝尔海姆重型后勤人员在科隆大教堂从事一项艰巨的起重机工作,给人留下深刻印象。大教堂北塔上的一个巨大的悬空脚手架在100米左右的高度被拆除。

夜间繁重的工作:有限的空间使设置工作成为一个挑战。

铝制脚手架必须从大教堂塔楼上拆除,不仅要在海平面以上100米处拆除,而且三个部分的外伸部分几乎相同。利勃海尔LTM 1750-9.1移动式起重机正在运行,最大吊钩高度为154米。

地下车站上方的起重机场地为规划团队提供了主要障碍。但经过长达两年的精心准备和计划阶段,Wasel GmbH掌握了起重机的工作,在物流和结构方面也不乏挑战。

行动中的挑战和解决方案

精心的项目准备是有回报的。在起重机车辆定位后不到8小时,基本装置配备了支架、Y形悬架和伸缩臂延伸装置,包括枢轴部分和镇流器。

LTM 1750-9.1安装在车站前院。在起重机安装区域下方的地下火车站,需要复杂地寻找大型起重机支架混凝土基础浇筑点。此外,必须考虑到车站外的大量人群。

瓦塞尔公司技术总监于尔根•奥普雷承认:“这项工程已经提前让我们头疼了。”。“我们必须在集合计划中考虑车站疏散计划,还必须随时保持逃生和救援路线畅通。我们还为设立工作分配了非常紧张的时间框架。”

科隆中央车站非常繁忙。装配起重臂所需的前院区域仅在夜间被封锁。此外,分配的区域太小,无法将格构吊杆装配到地面上的全长。动臂必须装配在悬挂位置。所需零件必须在正确的时间分娩。

从晚上10点开始,该区域被封锁,以便悬挂安装格构吊臂。用利勃海尔LTM 1095-5.1组装格构段需要全面部署,瓦塞尔团队整夜全神贯注。凌晨时分,繁荣终于延伸到科隆天空中的大教堂塔楼附近。

即使在安装时,移动式起重机的尺寸也很清楚。

来自德国和荷兰各地的许多鹤迷专程前往莱茵河畔大都会,以便能够观察到这次行动。

在众多观众的注视下,科隆大教堂历史上最大的起重机启动了。将构件固定在特殊的横梁上,以及从基础结构上松开相应的脚手架部件,这是这项行动中最乏味的部分。

巨大的铝元素缓慢到几乎无法察觉,开始运动。通过塔楼上起重机操作员和顾问的精确互动,7米宽、33米高的格子被谨慎地引导过去几个世纪的历史篇章和风化的天使人物。

“当拆除后脚手架时,在某些情况下,我们在货物和大教堂之间只有15厘米的空间,”瓦塞尔公司技术总监于尔根·奥普雷(Jürgen Oprée)谈到电梯的艰难空间条件时说。利勃海尔起重机在塔架之间向前移动大件货物,越过北侧过道,越过塔楼,最后使用LTM 1070-4.2将其放置在主入口前。

这项工作比原计划早得多。实际的起重机工作只花了大约四个小时。

瓦塞尔车队协调人约根·奥普里对比赛的顺利进行感到满意。“就在几年前,这样的工作是不可能的,”奥普拉解释道。“从技术方面来说,也许,但肯定不是在这么短的时间内。可能另一台起重机也会引起支撑压力方面的问题。LTM1750-9.1非常适合大教堂的这项工作。”
