The elements of hydraulic systems work together as one, converting the attempted compression of liquids into high-torque kinetic energy. If a single element in the chain of components fails, the whole system suffers a loss of efficiency or can fail completely. These...

Traveling across the country, it can be surprising how much of our cargo is still moved by rail transport. However, given the already existing infrastructure of railroads and engines, it remains a surprisingly affordable way to get cargo from one end of the country to...

A frequent sight at road construction and repair sites, the road grader is immediately identifiable with its centrally mounted blade sitting between the single front axle and double rear axles. Though it looks simple in design, the precision required for ground...

Hydraulic systems on heavy equipment are not cheap. Making sure your systems are in perfect shape is the key to not having to pay for expensive repairs or even component replacements. The primary way of caring for these critical systems is via preventive maintenance....

When admiring our heavy hydraulic equipment, we usually pay the most attention to the motors, pistons, and cylinders that convert hydraulic pressure into torque. But of equal importance are all of the “parts” that go along with our hydraulics systemsw—without which...

When we discuss “cranes,” we usually think of the skyscraper-sized machines we see erecting new buildings, or sometimes the smaller units on the backs of trucks used for smaller jobs. But what is the story with cranes that are designed to stay in one place? A great...

Hydraulic systems are used throughout industry, in construction, manufacturing, and automotive design. The long-recognized power of the force multiplier of pistons moving against incompressible liquid means that hydraulics make for a great power-to-weight ratio,...

Hydraulic systems are, by their nature, sealed systems—designed to keep the internal working separate from the surrounding environment. But what happens if foreign substances do somehow manage to get into the system? How does one address it before it becomes a...

The principles of fluid dynamics and hydraulic systems have been understood for most of human history. Despite the age of the science behind it, hydraulics remains in use everywhere in the modern world—from home plumbing to spacecraft. Nowhere is this more apparent...
