In hydraulic systems, proportional flow control valves ensure that flow rates remain virtually constant. In doing so, they have to meet a large number of performance criteria that extend beyond their core function. According to engineers at Bucher Hydraulics, manufacturers and operators of mobile machines are increasingly placing a special emphasis on energy efficiency. Flow […]
Biden owes a debt of gratitude to the mobile industry
The Association of Equipment Manufacturers represents more than a thousand companies involved in the construction and ag industries, including many suppliers of fluid power components and systems. These firms contribute over $288 billion a year to the U.S. economy and support 2.8 million high-paying jobs. So it goes without saying that AEM carries a bit […]
Nine reasons why your pump runs slow
In a recent 2021 Fluid Power Technology Conference — Virtual Series presentation, MSOE University’s Tom Wanke took an in-depth look at Pump and Motor Troubleshooting, Failure Modes and Analysis. One problem that drives engineers and maintenance technicians crazy is when a hydraulic pump underperforms or runs erratically, but doesn’t completely fail. Sorting out the root […]
Volvo delivers first electric compact machines
Volvo Construction Equipment’s ECR25 Electric compact excavator and Volvo L25 Electric compact wheel loader were first unveiled at the Bauma 2019 expo in Munich. Two Norwegian companies, K Baugerød Anlegg and Veidekke, were among the first to take delivery of the new machines, which took place at a socially-distanced handover event to comply with local […]
Komatsu dozers get smarter
Komatsu D51i-24 (131 hp) and D61i-24 (168 hp) dozers are now available with Komatsu’s intelligent Machine Control (iMC) technology. According to the company, the iMC 2.0 system can help quickly transform construction job sites into highly efficient, highly productive operations. iMC incorporates a host of advanced machine controls, software and components. For example, 3D design […]
Rugged transporter handles Antarctic extremes
An innovative design based on proven hydraulics and sophisticated controls ensured reliable and efficient performance. Prinoth Panther tracked vehicles are used on challenging worksites around the world. The rubber-tracked crawler carriers minimize damage to the underlying terrain thanks to their low ground pressure and superior stability while carrying payloads of up to 23 tons. They’re […]
Fluid power’s green evolution
All indications are that mobile and industrial systems of the future will be more automated and more digitally connected. And many experts contend future systems will also increasingly be low-carbon and electrified. Some construction equipment OEMs, for example, are committed to autonomous control and cloud-based maintenance systems, and next-generation machines that reduce the environmental impact […]
Pioneering electrohydraulic cylinder increases equipment fuel efficiency
Volvo Construction Equipment and Finland’s Norrhydro have developed a digital hydraulic actuator that reportedly boosts productivity while radically cutting fuel bills and CO2 emissions in construction applications. If widely adopted, it could help the mobile-equipment industry meet its sustainability ambitions while at the same time revolutionize machine hydraulic performance. While the full details of the […]
bauma China opens this week
Despite the ongoing COVID-19 crisis, bauma China will open this Tuesday in Shanghai. More than 28,000 exhibitors and 130,000 visitors are expected, and a number of U.S. and European-based fluid-power companies will have local representation at the show. Here’s a look at several new offerings for the fast-growing Chinese mobile market. Danfoss Power Solutions will […]
Ultra-large excavator has high-efficiency hydraulics
Hitachi Construction Machinery plans to add the EX2000-7 ultra-large hydraulic excavator to its line of mining machinery. The redesigned unit, slated for introduction next year, is based on the current EX1900-6. The model reportedly will feature an entirely new hydraulic circuit that reduces fuel consumption by up to 19% with no loss in productivity. Powered […]
