How is telematics used on mobile machinery?
In many ways, Industry 4.0 has yet to achieve widespread proliferation throughout fluid power machinery as it seemed we were promised. Baby Boomers are still waiting for their flying cars as promised by the Jetsons. It’s been nearly sixty years since the Jetsons got our hopes up, so I hope it doesn’t take so many […]
How does hydraulic cylinder repair work?
By Josh Cosford, Contributing Editor When well cared for, hydraulic cylinders should last decades. So long as they were designed for their application — meaning they perform within the bounds of their environment — there should be no reason for damage or wear outside of regular use. The mount, rod and raw material should have […]
Space-saving, pressure-compensated flow control valve
Sun Hydraulics has released the company’s first solenoid-operated, 3-way proportional flow control valve as part of the expanding line of FLeX Series valves. The new patent pending, compact FREP combines an electro-proportional adjustable orifice and pressure compensator in one valve and can provide a constant priority flow rate independent of load pressures. It’s well suited […]
Sectional load sense relief valve offers efficient pressure control
Power management company Eaton has introduced a sectional load sense relief valve (LSRV) for its CLS mobile hydraulic control valve. The patented LSRV limits individual section pressure through feed oil reduction, eliminating the need for inefficient work port reliefs for feed-side pressure control. The CLS LSRV improves machine productivity and efficiency by helping prevent functions […]
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 […]
Work Truck Show reimagined as week-long digital event
Work Truck Week 2021 will be held online March 8-12, offering product updates, demos, online conferences and virtual exposition. The Work Truck Show, which was probably one of the last events any fluid power professionals attended last year, is now Work Truck Week. NTEA – The Association for the Work Truck Industry has reimagined Work […]
What are the most common hydraulic cylinder piston rod problems?
By Josh Cosford, Contributing Editor It would help if you never underestimate the importance of your cylinder rod. The rod is not just the object transmitting the force from the cylinder’s piston but also the interface between that cylinder and your machine. Before you can correctly select and then design the piston rod, you must […]
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 […]
Rating the real performance of hydraulic pumps
Low- and high-speed tests show that pump and motor performance can vary widely, depending on the speed and pressure. That’s critically important in electro-hydraulic actuators and electric-motor drives. Contributed by Peter Achten and Robin Mommers, Innas BV, Breda, The Netherlands Hydraulic component manufacturers generally publish pump and motor data that reflect optimal performance under ideal […]
