The Challenge
NACCO Materials Handling Group (NMHG), a leading producer of lift trucks, was facing a significant challenge in their product development process. The company had been using finite-element analysis (FEA) for 25 years, but this required the construction of several iterations of physical prototypes to test their designs. This process was not only costly but also time-consuming, leading to delays in bringing products to market. The company was in dire need of a solution that could reduce the time to market without compromising on the quality of their products. The ultimate goal was to virtually design, test, and evaluate each product before any physical prototypes were made, thereby saving costs and gaining a competitive advantage.
About The Customer
NACCO Materials Handling Group (NMHG) is a globally recognized company that designs, engineers, and manufactures materials handling equipment for virtually every type of market. Their products, sold under the brand names Yale® and Hyster®, are used by businesses around the world that require forklift trucks, container handlers, and electric warehouse vehicles. NMHG is one of the world’s largest producers of lift trucks. The company operates a Counterbalanced Development Center in Fairview, Oregon, where it develops a wide range of counterbalanced sit-down forklift trucks. This center also serves as one of the global centers of excellence for computer simulations used by the company’s network of development centers around the world.
The Solution
NMHG adopted Altair’s HyperWorks suite of simulation tools to address their challenges. The suite was chosen after a thorough comparison with ten other products from vendors across the globe. HyperWorks allowed NMHG to reduce the amount of physical prototyping needed for products, thereby cutting both costs and time to market. The suite also provided NMHG with new capabilities. For instance, OptiStruct enabled engineers to optimize a design based on fatigue, an approach that held great potential for the company. Altair’s RADIOSS opened the field to a broad range of simulations, previously run with an implicit code. The company also used MotionView and MotionSolve for multi-body dynamics analysis. The suite's pre-processing capabilities were found to be extremely simple and powerful with HyperMesh.

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.
