View ArticleTwo Speeds Keep CTLs on Track
Sponsored by Eaton Compact track loaders (CTLs) have been the fastest-growing segment of the mobile equipment market since the start of the century. With broad, high-flotation rubber tracks, these...
View ArticleInverter-Driven Hydraulic Power Units
TP and TV series hydraulic power units feature a variable-speed electric motor driving a piston or vane pump, respectively, to match pressure and flow output to demand. The result is 35 to 65%...
View ArticleWhat to Consider When Selecting a Hydraulic Motor
Sponsored by Eaton What are the major considerations I need to think about when designing in (or replacing) a hydraulic motor? When considering reliability, what key...read more

View ArticleLoader-Backhoe Offers Power, Low Maintenance, and Economy
Alan Hitchcox Case Construction Equipment's 580N EP is a lower-horsepower version of the 580N with the same lift capacity and breakout force with greater fuel efficiency. Case Construction Equipment,...
View ArticleHydraulic-Electrical Analogies: Transmission Comparisons, Part 1
The hydrostatic transmission and Ward Leonard generator-motor drive are so perfectly analogous to one another that they must be included in any complete review of analogies. The hydrostatic...
View ArticleHydraulic Motors Give Mexican Dam a Big Lift
Electromechanical drives on spillway gates at Mexico’s Malpaso Dam needed to be replaced. Low-speed, high-torque hydraulic motors proved not only to be the best solution, but also serve as a blueprint...
View ArticleAn Alternative to Displacement Controls
James D. Van de Ven, University of Minnesota Variable-displacement pumps have emerged as an energy-efficient means of matching hydraulic power transmission to a varying load. The latest method under...

Troubleshooting Challenge: Drill Rig’s Top Drive Drops Uncontrollably
When a drill-rig operator started the unit and commanded the top drive head to be lowered, it dropped uncontrollably, damaging the drill bit or buckling the drill string. read more
View ArticleHydraulic Cylinders Keep Their Cool
Alan Hitchcox Intense heat is often the Achilles heel of any form of power transmission unless special provisions are made. Hydraulic cylinders often operate under conditions that would quickly...
View ArticleMath Models for Hydraulics Coming to ISO
Design methodology will increasingly use an analytical highway that is paved with an innovative, yet practical, set of new first principles using ever more powerful computers.read more
View ArticleHydraulic-Electric Analogies: Transmission Comparisons, Part 3
Analytical schematics reveal the analogous nature of pumps and generators—both suffer resistance losses that lead to inefficiencies. Analytical schematics reveal the analogous nature of pumps and...
View ArticleDifferent Driver, Different Torque
A Staff Report Electric motors can produce starting torque several times that of their operating torque. This gives them an advantage over gasoline and diesel engines for driving a pump in a hydraulic...
View ArticleSuction Strainers, a Hungry Donkey, and the Paradox Of Choice
We’re faced with decisions every day. Decisions on minor issues are fairly easy because wrong choices carry little or no consequences. But what about technical issues, such as whether you should use a...
View ArticleDouble-Indemnity Insurance for Your Pump
Perhaps a compromise can be reached when it comes to the argument of whether or not to use a suction strainer—incorporate a bypass.read more
