During a circus act, a clown balances on a platform resting on the end of a 60-ft pole. The platform has a double rail on all four sides, and the top rail is about waist high. The clown acts like he is trying to cause the pole to sway back and forth, which causes it to break loose and drop to about 30 ft above an open cage holding tigers and lions....More

Analogies exist between hydraulic flow and electrical flow, and the molecules of fluid in a hydraulic circuit behave much like the electrons in an electrical circuit. Let’s examine analogies between pressure and voltage and between ground and the hydraulic reservoir....More

Although most hydraulic and pneumatic manufacturers are reporting orders and shipments down across the board, Bosch Rexroth reports the highest revenues in its history....More

The wind power and petroleum industries may be seen as rivals, yet oil is essential throughout a wind farm to ensure smooth operation. As such, it is necessary to select the right accumulators for both hydraulic and lubrication applications. Wind turbine manufacturers typically speak of having availability levels in the range of 97% to 98%, but a 2008 study by British wind consultants Garrad Hassan found actual availability levels to be lower. In North America, turbines were averaging an availability of 94% to 95%....More

Allow me to preface my article with a recent accident: A maintenance technician was nearly killed when the tilt cylinder hose assembly that was made by an untrained technician unexpectedly failed, causing the mast to tilt forward and stop a few feet from a steel structure. The victim was apparently spared from severe injury, and possibly death, for two reasons. First, he was wearing a safety harness....More

One of the strengths of hydraulics is in its unsurpassed versatility to create and control motion. You can do many things accurately and with tight control, but the plethora of available components and manufacturers can be dizzying, especially when so many companies make many versions of the same thing. I’d say pumps are the most confusing product for the average fluid power learner to get their heads around, but hydraulic motors are a close second....More
