Excellent write up of Hydraulics

Good posting on this subject.  I appreciate the comparison to electric systems and the benefits to be gained by applying hydraulics.  I have long suspected that the trend to shift as much as possible to electric positioning systems and such might not always be the best approach.

Yes, excellent write up.  Sometimes going back to the simpler designs produces a great improvement.  The one issue, though, is that hose breaking is a bit more problematic than a wire.

Let's be clear here.  This article argues that hydraulics are more efficient than GEARBOXES, not electric motors.  Most hydraulics are powered by electric motors in the first place, and I am quite sure that a high efficiency direct drive brushless motor is more efficient than the induction motors usually used for hydraulics.  However, if you have a gearbox in the drive train, you often lose 40% to the gearbox, and his points about bulk and weight are still well taken in certain applications.  However, it is important that we think clearly about where the inefficiencies are or we will solve the wrong problem.

HYdraulics may be more efficient than some gearboxes, but in many cases the better efficiency would come from being 100% electric everything. What hydraulics can do very well is put the most energy in  a small place, and a cylinder will live well even if you stall it So there is a time and place where hydraulic power is the best choice, but it is not everywhere. Most time changing to hydraulics is not done for efficiency.

Excellent post and hydraulic pumps

Excellent post. I want to further support the importance of properly sizing the hydraulic pump for the machine. An inproperly sized pumped, as most of you know, can cause all sorts of expensive problems.

With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
US factory orders for durable goods tumbled 3.4% in December on a big drop in new bookings for commercial aircraft, according to data the Commerce Department released Tuesday.
