Mobile machine designers are often faced with the following dilemma: accommodating quite a large functionality in the smallest possible installation space. Some mobile machines and utility vehicles must comply as well with unambiguous regulations regarding the width or height of the vehicle. The difficulty of this task becomes particularly evident when additional functions are to […]
Tilting coupler technology helps in construction application
Ray Clapp, owner of Coast Range Construction, Homer, Alaska, was searching for a way to increase efficiency on job sites. Coast Range specializes in setting foundations for lodges and cabins as well as performing house-site development for contractors. Homer has very little flat ground to build on. Terrain ranges from sea level up to 1,400 […]
Progressive versus linear spools in Danfoss PVG mobile proportional valves
Contributed by Buck Schmitt, CFPS, Territory Manager – Eastern PA and Mid-Atlantic, Kraft Fluid Systems When designing hydraulic systems for mobile machinery, there are a variety of requirements that range from basic setup functions to extremely precise maneuvers. Let’s examine the more precise and critical functions. There are several ways to approach hydraulic system challenges. […]
We’ve come a long way, baby: the evolution of construction equipment hydraulics
Modern mobile machinery has changed quite a bit. Here is a look at how construction equipment hydraulics have changed over the last couple hundred years. By Josh Cosford, Contributing Editor On a road near my home, there exists a hand-laid stone fence, perhaps 4 ft high and a hundred times as long. Crafted from locally-sourced […]
Mobile hydraulics gets an unwelcome jolt
One unmistakable take-away from this year’s bauma show was the buzz surrounding electrification. The idea of massive mobile machines running only on batteries may seem far-fetched, but for smaller equipment it has become a reality. At every turn, major manufacturers like Cat, Kobelco, Komatsu and Volvo to niche players like Ecovolve and Giant featured electrified […]

Bucher Hydraulics announces “revolutionary” new pump design
The performance of traditional hydraulic pumps has not kept up with increasingly stringent customer demands and new application requirements, according to officials at Bucher Hydraulics, Klettgau, Germany. They’re tackling such concerns with a new design for piston pumps and motors called the AX series. The AX is not an evolutionary improvement over existing products, said […]
Transforming mobile machines
Like the construction equipment industry as a whole, the Mobile Hydraulics Group of Bosch Rexroth enjoyed a good a year in 2018. “Our efforts to restructure the company and gain market share definitely paid off,” said Bernd Schunk, Senior Vice President Sales for Mobile Hydraulics. “We generated another double-digit increase in revenue, boosted by the […]
Learn the latest in mobile hydraulic technologies at FPTC 2019
It’s no secret that mobile machinery is possibly the biggest user of hydraulic technologies. Hydraulic components are ideal because they offer the power density required to move heavy loads used in construction, the precision required in agriculture and the safety of mining. As a result, many of the sessions at this year’s Fluid Power Technology […]
