Volvo’s new EC300E hydraulic hybrid excavator will make its debut on the North American market at ConExpo-Con/Agg 2020 in Las Vegas. Its performance is based on straightforward technology that stores hydraulic energy from machine motions in an accumulator, and then reuses it to supplement subsequent actions. The hydraulic hybrid assist system is 100% Volvo-engineered, said […]
Redesigned hydraulic system speeds loading on new excavator
With its PC2000-11 hydraulic excavator, Komatsu America, has created a machine that is designed to load 70- to 200-ton rigid frame haul trucks faster. Equipped with an EPA Tier 4 Final certified engine, the PC2000-11 has more horsepower and a new engine-pump control for faster cycle times and improved multifunction performance. Redesigned hydraulics and cylinder […]

Novel circuit boosts machine efficiency on Forwarder2020 project
European researchers recently wrapped up the three-year Forwarder2020 project, which aimed to develop a next-generation forwarder that’s more efficient, productive and environmentally sustainable than anything currently in use. Engineers are now reporting preliminary findings from lab tests and field trials, with encouraging results. Forwarders are articulated vehicles that carry felled timbers from the woods to […]
What is the difference between tie-rod and welded cylinders?
Although both types of cylinders are used in fluid power systems, the end caps used to hold the cylinder together make the difference. Welded cylinders are designed with each end cap welded to the barrel. Mounts and other fittings will also be welded to a cap. Static seals are used to seal the head or […]

Fluid power shines with Agritechnica awards
Agritechnica, one of the world’s largest trade fairs for agricultural technology, opened this week in Hannover, Germany. According to organizer DLG (German Agricultural Society) the show is expected to attract more than 450,000 attendees from 130 countries over its seven-day run. One highlight is the announcement of this year’s Innovation Awards, a competition open to […]
Corex rod coating aids mining machine development
By Steven North, design and project engineer, Apex Hydraulics Apex Hydraulics has a long history of producing custom built and highly specialized hydraulic cylinders for mining applications. When the company was formed in 1985, the main source of work was from mining. Now, most work comes from oil, renewable energies and factories. However, due to […]
What are PTO through-drive motors?
By Josh Cosford, Contributing Editor If you’ve spent any reasonable amount of time working on or around mobile machinery, you’re very familiar with PTO-driven machinery, including the hydraulic pump. The PTO shaft exiting the rear of a farm tractor is used to power mechanical implements through a drive shaft, such as bailers or mowers, themselves […]
