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...

Not every construction project takes place downtown (despite the way it may seem during rush hour). There are dozens of construction projects near you right now taking place in new developments, in out-of-the-way areas, and even in older neighborhoods undergoing urban...

Easily the most recognizable of the heavy equipment seem at construction or dig sites, excavators have a very imposing appearance. With the huge arm at the front and the myriad of potential accessories attached, these machines can range into tens of tons in weight and...

The hydraulic fluid inside your heavy equipment is the lifeblood of your machine—without it moving to power the different components in your hydraulic system, your dozer or crane is nothing more than a very expensive collection of metal. So it’s critical to maintain a...

Wherever you go in the world of heavy equipment, you will find hydraulic cylinders. Using long-understood principles of hydraulic science to operate, hydraulic cylinders are reliable, and they also provide an enormous amount of power for the space they take up. But...

Cranes are found everywhere these days—construction sites, docks, railyards—the list goes on. However, the infrastructure required to put a traditional crane in place often makes them very limited in their usage. Unlike a traditional crane with its fixed boom length,...
