关于客户
STROS 拥有 50 年的经营历史，是世界领先的建筑工地起重机械供应商之一。它提供高质量的工作平台以及定制的人员和物料升降机。
挑战
由于每个桅杆部分总共需要 222 个可靠的焊缝，因此制造它们是一个劳动密集型的过程。
直到最近，STROS 还必须使用技术精湛的焊工来制作这些部分。尽管它已经使用机器人 25 年，但这些机器无法在这些特定组件所需的狭窄空间内管理复杂的弧焊。因此，为了生产令人满意数量的桅杆部分，每班必须在三个独立的工作站雇用三名焊工来制造这些部件。除了人力和空间方面的明显支出外，STROS 发现招募这项工作所需的高素质焊工越来越困难。这就是为什么该公司在 2007 年决定为桅杆部分制造过程的完全机器人化举行招标。在参与的四家公司中，只有 ABB 集团能够满足其所有要求。
解决方案
工艺臂与定位器的流体交互是一个令人印象深刻的同步性壮举，根据 Škorpa 的说法，如果没有 ABB 准备好与 STROS 密切合作来设计系统，这是不可能实现的。 STROS 使用带有两个工作站的旋转 IRBP 500 D 定位器来固定桅杆部分的各个部分，这些部分要在最终部件完成之前进行焊接。这意味着机器人一直在使用，因为操作员可以在定位器的一侧准备要焊接的部件，而另一部分正在焊接。
然后定位器旋转并继续焊接，同时操作员移除另一侧的已完成零件并准备下一个组件。制作一个桅杆部分的标准联合循环时间为 54 分钟，这比人工焊工制作同一件所需的时间快三倍。

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.

Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
