Hydraulic Pump Displacement Controlled by Solenoids
A new radial-piston pump design uses solenoid valves instead of a swashplate to vary displacement.

Self-Contained Electrohydraulic Actuator Offers Failsafe Operation
Gas and steam turbines often integrate hydraulic cylinders for valve-actuation purposes. Hydraulic cylinders usually can transmit extremely high force and precise position and force control within a much smaller package than electromechanical actuators.
Advanced Machine Tools Revitalize Cylinder Manufacturing
In 2011, Jim Warneke, general manager, and Frank Laratta, manufacturing engineer, both arrived at Hanna Cylinders, Pleasant Prairie, Wis. Their first major project was to give Hanna a much needed “manufacturing face lift,” as they put it, to shorten production lead times.
Hydraulic Cylinders Provide Muscle for Pipelaying

Enerpac supplied dozens of high-pressure hydraulic cylinders for the topside lift system beams on Allseas ‘Pioneering Spirit’ vessel. The cylinders are an integral part of the vessel’s lift system, enabling the installation and decommissioning of complete topsides weighing up to metric 48,000 tons. ‘Pioneering Spirit’ is the largest platform installation, decommissioning, and pipelay vessel in the world. The vessel’s 16 lifting beams feature 64 Enerpac CLRG-Series  double-acting hydraulic cylinders arranged in groups of four.

Combining Functions Saves Time, Cuts Cost, Improves Quality
A slip ring and hydraulic swivel cohesively designed together as a single assembly improves economies of scale and reduces the number of components, suppliers, and the potential for component failure.
Toughened-Up Hitch Control Also Drops in Price
When introducing an electrohydraulic hitch control to the Indian market, engineers had not accounted for the hostile conditions typically found on Indian farms. After some seat-of-the-pants modifications, a revised hitch control not only stands up to tough conditions, but carries a lower price tag as well.
The Many Roles of Accumulators
Accumulators, which store energy by compressing a gas, are useful for reducing rapid dynamic behavior of a hydraulic system.
Raymond F. Hanley, Champion for Fluid Power Certification

Raymond F. Hanley passed away Saturday, May 30, 2015 at the age of 89. He was born February 10, 1926 in Altoona , Pa and died at the Earl Hadlow Community Hospice Center in Jacksonville, Fla.

Hanley was a depression-era child born in Altoona, Pa. He entered the Navy in 1943 and was assigned to the USS McGinty, a destroyer escort in the South Pacific.  Ray’s duties on the ship included ship’s photographer, mailman, and helmsman.  His primary duty on the ship was anti-submarine warfare, which included operation of a 50-caliber machine gun.

Remembering the Henry Ford of Fluid Power

It’s graduation time, and all across America, dignitaries are giving speeches telling graduates to make a difference and change the world. Changing the world might be a bit overly ambitious, but each of us can certainly make a difference in our part of the world.

HAWE Creates New Service Division

During its North American Partner Meeting last month, HAWE Hydraulics North America, Charlotte, N. C., announced the launch of a new division: HAWE Service Solutions (HSS). This year’s meeting took place in Vancouver, BC and connected HAWE’s North American distributors with HAWE employees from Germany and the US. For years this annual meeting has served as a conduit to discuss new products and the overall direction of the company as a whole.

Fluid Power Associates Becomes Atos North America

Atos SpA, Sesto Calende, Italy, announced today that it has acquired full ownership of Fluid Power Associates, Inc., an import, distribution, and repair center for electrohydraulic components in which Atos held a minority stake.  The name of the newly restructured company is Atos North America.  The purchase will allow the Italian hydraulics manufacturer to better operate in the North American market by providing a larger local stock, enhanced technical support, and better customer service.

CFC Training Hits 25-year Milestone

CFC Industrial Training, a division of CFC Solar, Inc. began a year-long celebration of 25 years as a global leader in providing industrial skills training and consulting for companies across the US, Europe, Latin America, and the Middle East.

Has the Next Generation Arrived?
Aside from a big jump from analog to digital control, electronics in fluid power has gone through evolutionary changes. Components with Bluetooth and similar wireless communication have only recently been introduced to the fluid power market, though.
Smart Actuation of Pumps and Valves
New actuation technology holds promise to do away with the need for pilot circuits for valves in mobile hydraulic systems.
Like Magnets on Steroids
This hydraulic filtration technology combining magnets and specially formed steel plates collects sub-micron and larger-sized contaminants from hydraulic fluid.
