Why hydraulic efficiency is becoming critical
Given the heightened attention on climate change and growing regulatory attempts to rein in CO2 emissions, the push toward electrification of mobile equipment is gaining momentum. Mobile OEMs are in the infancy of a major transformation toward electric-powered systems, but success in large part hinges on more-efficient fluid power systems. Why does hydraulic efficiency matter? […]
Versatile machines thanks to electronic pump controls
Manufacturers of mobile machines must decide whether to control their pumps using pressure, torque or swivel angle — and always have to accept compromises as a result. The same applies to numerous other hardware parameters which, once defined, stay the same throughout a machine’s service life. According to Simon Dreher, an excavator industry specialist with […]
Swing-axle cylinders combine travel comfort with rigid work platform
Mobile machines have to meet widely differing requirements. To get to a job site, they need good off-road capability. While they are working, however, high rigidity and stability are essential. Add to that are increasingly demanding safety and environmental regulations. Swing-axle cylinders are built to fulfill all these requirements. According to engineers at Bucher Hydraulics, […]
eLION platform for electrifying mobile machines
Manufacturers from all sectors have recognized that electric drives are an important building block for future viable, sustainable mobile machines. To support and encourage the electrification of off-highway equipment, Bosch Rexroth is now presenting the eLION product portfolio. The eLION family covers a wide range of components, including a full range of electric motor-generators, inverters […]
Can a dirty industry come clean? How mining equipment is becoming more sustainable
Anyone who has worked underground or in surface mines knows that it’s a hard and dirty job. And the process of extracting ores and minerals usually has a negative environmental impact. For instance, consider the haul truck. According to “Pulling the weight of heavy truck decarbonization,” a report published by the Rocky Mountain Institute, globally […]
Fuzzy-logic controls simplify crawler excavator controls
New XCMG products unveiled during MINExpo are reportedly adapted to work under highly challenging conditions. The 95-ton XE950G crawler excavator, with a bucket capacity of 6 m³, is an efficient and energy-saving model featuring advanced controls, a behavior monitoring system and industry-leading dual-pump independent technology, according to the company. It is said to excel in […]
Powerful demolition robot features more effective hydraulic breakers
The new Brokk 900 is said to be the world’s largest and most powerful demolition robot. Compared with its predecessor, the unit features enhanced design, more rugged engineering and 25% more power, which translates into more-effective hydraulic breakers. All this comes with almost no increase in size and weight. The machine’s SmartPower control and monitoring […]
Hitachi mining excavator gets hydraulic system upgrade
Hitachi Construction & Mining, a division of John Deere Construction & Forestry Co., announced the EX2000-7 — its latest EX-7 series mining excavator that is said to enhance efficiency, reliability and durability. Its new Cummins QST30-C engines cut fuel consumption for significant cost savings and lower environmental impact. Hydraulic pumps optimized with electronic regulation, high […]
Volvo expands range of electric-hydraulic machines
Volvo Construction Equipment has introduced three new electric compact machines, the L20 Electric wheel loader and EC18 Electric and ECR18 Electric excavators. The units join the current L25 and ECR25 electric offerings, and give Volvo the industry’s largest range of electric-drive machines, according to company officials. Volvo CE’s growing range of electric-drive equipment is said […]
