Founded in 1951, Hydraquip – a 100% employee-owned company in Houston, Tex. – offers system design, service and repair, and fluid conveyance through many world-class manufacturers. Through partnering with its sister companies, Hydraquip can provide turnkey systems, engineering, and fabrication capabilities. In 2014, it was named one of the Top 10 Places to Work by the Houston Business Journal.
Stamping presses that form and bend metal under pressure are themselves under pressure to improve throughput, process cost control, and energy efficiency. Many stamping presses have been in operation for 20 to 25 years and typically operate under punishing conditions – with cycle times between 100 ms and several seconds, and utilization rates ranging from 3,600 to 6,000 hours per year.
At Franco Dragone’s The House of Dancing Water, electrohydraulics runs the show. The production takes place in Macau, China’s City of Dreams. The theater holds more than five Olympic swimming pools, making it the largest water-based theater in the world. During the show, professional divers, dancers, acrobats, swimmers, and even motorcyclists perform daring feats that rely on the smooth, fluid operation of a highly dynamic stage.
Jim Barry, Michael Batchelor, TJ McDermott and Rick Rice—these are individuals you need to know. Four of the most expansive thinkers in the machine-building technology space, these engineering veterans comprise the Control Design Editorial Advisory Board.
As an introduction, they shared their thoughts on a variety of topics, from motion control and wireless sensing to control platforms and cybersecurity.
Most hydraulic systems will operate satisfactorily using a variety of fluids. These include multigrade engine oil, automatic transmission fluid, and more conventional anti-wear hydraulic oil. But which type of fluid is best for a particular application? While it is not possible to make one definitive recommendation that covers all types of hydraulic equipment in all applications, the following are some of the factors that need to be considered when selecting (or changing) a hydraulic fluid.
Machine builders: Don’t let the latest hybrid drives and controls take you by surprise. They’re breathing new life into pneumatics and hydraulics, boosting the efficiency of equipment and saving users lots of money.

Pneumatics and hydraulics may be too old fashioned for some engineers, but not for Klaus Lange. The operations engineer at Haefner and Krullmann GmbH near Bielefeld, Germany has become a believer in the benefits of bringing hydraulic machinery into the digital age. For he and his colleagues at this producer of thermoplastic spools and environmental containers experienced these benefits firsthand when they joined a growing group of manufacturers who are integrating electric drives with fluid power.
