Sustainable machine designs top Bauma innovations

December 8, 2022 By Mary Gannon

Suitable for use under extreme temperatures, shock, and high-dust conditions on construction sites, the 50 ton-operating weight R 9XX H2 may in future offer a robust solution for earthworks and quarrying applications.

While many compact machines boast all-electric systems, several prototype designs feature alternative options to power larger, heavier-duty equipment. At Bauma this past October, most mobile machinery makers touted new or prototype designs that feature low-carbon, sustainable systems. Electrification was a hot topic as it has been, but all-electric designs were mostly limited to compact machinery. […]

Where are compact hydraulic power units used?

November 17, 2022 By Mary Gannon

compact hydraulic power units AdobeStock_85203139

By Josh Cosford, Contributing Editor Hydraulic power units are both the source of hydraulic energy and fluid conditioning. The hydraulic reservoir provides a mounting surface for the hydraulic pump and its prime mover while offering up real estate to mount filters, coolers, valves and accessories. In addition, the reservoir stores the hydraulic fluid, providing a […]

Moving from point A to B with hydraulics

November 1, 2022 By Mary Gannon

Figure 1. The high-lift LH 80 M from Liebherr is designed for use in heavy-duty material handling in the area of scrap, timber, and harbour operations. It is equipped with the patented Liebherr ERC System (energy recovery system), that gives the machine a performance boost while also saving fuel.

Mobile material handling machines rely heavily on hydraulic technologies which pair well with the robust, sometimes challenging environments these machines work in. By Josh Cosford • Contributing Editor Material handling machines are some of the most widespread hydraulic applications developed. Where you must move product or material, a hydraulic machine is available to help. Industrial […]

Contributed by Tracy Jones, Director of CJ Plant Maintenance The challenge with hydraulic pumps is that they are often neglected until something goes wrong. You wouldn’t be blamed for not knowing how often you need to service your hydraulic pump or how often it needs maintenance. However, some common signs indicate when your pump needs […]

By Josh Cosford, Contributing Editor Do me a favor — stand up near a wall just out of arm’s length reach. Now raise your arm with your palm facing the wall and very slowly move toward the wall. Without yet touching the wall, tell me where the force comes from to move your body close […]

Overcoming the roadblocks to fluid power education

August 11, 2022 By Ken Korane

Hydraulic fluid power education book cover

Nearly 30 years ago, the late Bob Koski of Sun Hydraulics made a provocative presentation titled “Fluid Power Education – What went wrong?” He noted that every mechanical and electric engineer learns about electrical power actuation and motion control, but only about 5% of mechanical engineering graduates learn about fluid power actuation and control. The […]

Sorting out auxiliary hydraulics for mobile machinery

June 23, 2022 By Ken Korane

the recently introduced case tv620b ctl comes with a standard high-flow auxiliary hydraulic system.

Understanding the hydraulic system is critical when choosing work tools and attachments for mobile machines. George MacIntyre and Ted Polzer, Product Managers, Case Construction Equipment, Racine, Wisconsin Skid steers and compact track loaders (CTLs) are two of the most useful pieces of mobile equipment, and adding attachments makes them all that much more versatile when […]

Are hydrogen fuel cells the future for mobile machines?

June 17, 2022 By Mary Gannon

Adaptation of the active pre-chamber in Liebherr’s H966 and H964 engines has demonstrated that heavy-duty engines can be operated with hydrogen.

Prioritizing decarbonization is, without doubt, one that most countries agree with almost pure unanimity. Here, in the U.S., the Biden administration has a goal to eliminate carbons from the electric grid system by 2035. Globally, most countries are on similar timelines. But, looking ahead to 2050, there doesn’t seem to be a clear path forward […]

Novel tunnel-boring machine takes on mining with the help of hydraulics

May 2, 2022 By Ken Korane

Hydraulically powered unit is the first to cut rectangular tunnels in hard rock. Circular, full-face tunnel boring machines (TBMs) are well-engineered, proven pieces of equipment, and they’re considered the most efficient machines for mechanical excavation of tunnels in rock. But they are not often used in underground mining. That’s because mines generally require a flat […]
