You can’t get something for nothing

November 12, 2020 By Josh Cosford

A float trailer like this one was not able to lift the load required of it because of altered hydraulic pumps were not sized correctly.

I once had a customer call to request I visit them at their own customer’s site to help with a “breakdown.” I’m always down to help a customer, so I gladly paid a visit. Arriving on-site, many looming pieces of machinery greeted me in a heavy equipment yard. An excavator sat atop a float trailer […]

U.S. Navy wakes up, revisits hydraulics

August 14, 2020 By Ken Korane

In a push toward everything “cutting edge” and “high-tech,” the U.S. Navy in recent years has gone overboard — no pun intended — with the wholesale replacement of proven hydraulic-powered systems with untested electric drives. The results in many cases have been dismal. The $13 billion USS Gerald R. Ford aircraft carrier is the most […]

Rotational speed sensors allow highly sensitive mobile machine control

August 13, 2020 By Mary Gannon

Sugar beet harvesters from Homer Maschinenbau require precise data collection, provided by Rheintacho speed sensors.

Holmer Maschinenbau GmbH, a German-based agricultural company, developed the first self-propelled six-row sugar-beet harvester in 1974. Since that time, the Holmer machines have been in successful operation by customers in over 40 countries world-wide. On its sugar beet harvesters, it requires a precise collection of actual values directly at the place of consumption (propulsion, toppers, […]
