Case Study

Author:Arno Kijzerwaard

In a world where cargo transportation by means of intermodal containers keeps growing in volume, ship sizes show a steady increase as well. As a consequence, ports around the world have to invest in larger container cranes in order to handle these ships.

这些容器起重机的工作速度以及自动化水平都在增加。手推车旅行速度高达240米甚至每分钟300米,不再例外。在100 m的轨道上,这些手推车每年很容易行驶超过10,000公里。

在这些高速驾驶的启动维护的关键元素之一是手推车的车轮轨道触点引起的磨损。有效预防这种侵略性的磨损形式可以通过准确的手推车轮子对齐来实现。然而,在梁高度超过50 m的容器起重机上,这种对齐程序对测量仪器提出了极大的需求。


Staying on track

尽管对钢导轨上的一组钢轮的对准测量似乎是一种直接的活动,几乎任何人都有一个理想的人可以执行,但事实证明,当在风中移动的钢结构上高50 m时,这证明不那么简单。不要忘记一个人不得不走一半的世界才能到达那里。

The accurate alignment of trolley wheels on container cranes is such a specialty and niche market that the market area is simply formed by ports around world. Langeveld Cranes has almost a decade of development in this technique, bringing it to a whole new level. By now, their estimated amount of successful projects approximates 300 all over the world.

Langeveld一直在使用Leica TS30总站,最近在其设备篮中添加了Leica Nova TS60总站。TS60与Leica CS35平板电脑和Langeveld自己的专门开发的车轮对齐软件结合使用。


Working in the extreme

车轮对齐的公差可以追溯到1970年代。经典起重机设计标准均指定0.4 mm/m的最大允许轮角。但是,这与描述良好的跑步行为并不完全相同。通过从良好的跑步行为的一侧接近对齐,在实际的最终结果中实现了全新的精度水平。

这种新的准确性虽然有益,但对测量的准确性和可重复性提出了更高的要求。总站必须bob apple一遍又一遍地衡量需求。兰格维尔德的手推车车轮的校准的工作比起重机标准史上所指定的要准确得多。这本身就是一回事,但同样重要的是,这一结果始终在风中移动起重机上的码头高度超过50 m的高度上实现。

Climate is another critical aspect to consider. The temperature working range of measurement equipment is usually one line in the data sheet. Hardly a difficult specification to meet when measuring close to Langeveld’s home base in the Netherlands. This becomes a less theoretical value, however, when winter projects in Scandinavia are asked for, followed by tropical destinations around the equator.

经过数十个项目,TS30总站一直保持稳定。当然,在每个工作日之前,该仪器都会适应。尽管如此,在这条工作线中,环境温度的极端变化不再是理论上的值。

“在世界各地的每一个可思考的气候中,我们的莉卡地理系统总站都进入了几乎所有大洲的港口,并通过非洲,中东,亚洲和南美许多国家的定制官员的手中。bob apple”Langeveld项目管理所有者Casper Langeveld。“无论运输形式或环境条件的形式如何,这些总站都会继续工作,并为我们提供所需的测量。bob apple我们能够信任结果并确保为客户提供高质量的可交付成果。”


新趋势,新需求

Recent developments in crane automation have unexpectedly led to a complete new challenge. The classic crane driver was normally located almost directly above his load. Every move, shock and sound were immediately noticed and reacted upon. This could be anything between a radio call for a service engineer or, in a worst case, a full crane stop.

The recent trend of increased crane automation and remote control have effectively removed the driver from the crane. This means that there is no direct witness for unusual shocks or noises in the trolley behaviour anymore. Therefore, the trolley must run smoother than ever before, because any deviation in sound or shock will stay unnoticed for a far longer time.

满足国际要求和工作量,TS60对于该公司作为TS30的自然继任者来说是一个简单的选择。借助ATRPLU,TS60总站保持锁定目标的能力是最大化的,忽略了该领域的其他干扰,这在港口中可能很丰富。

由于Langeveld自己的软件在TS60上运行,而且还可以使用Leica Captivate 3D Field软件,这对公司来说是关键功能。这使内部通信能够与整个站点进行凝聚力的工作环境。bob apple

Langeveld说:“我们相信Leica Geosystems为我们的业务提供的整体强大解决方案。”“我们为起重机市场组成了一个强大的团队。”
