From construction to freight to salvaging forsaken ships at sea, current and early cranes are simply the arms that do the heavy lifting powering our global industries. The world just wouldn’t be the same without them””and it’s our goal to make sure your cranes will perform powerfully, flexibly, and effectively until the jobs are done.
So how did cranes become such an integral part of all of our lives (whether we realize it or not)? Let’s take a look back through history:
Democracy and Devotion: Greeks Invent the Crane
Necessity is the mother of all innovation””and you won’t find a more urgent group of inventors than those under threat of being smote from above. For whatever reasons, the Ancient Greeks felt compelled to build huge temples to their gods, and traditional methods like ramps for moving and lifting the enormous building stones of massive monuments like the Parthenon just weren’t going to get the jobs done. Meet the crane: at first a simple winch and pulley system, and later a compound pulley system credited to Aristotle.
Today, you can see the difference in the way temples were built in different time periods. Pre-cranes, building blocks actually tended to be much larger, because so much effort was required to push each one up a ramp that it was less labor-intensive to use bigger and fewer blocks. Post-cranes, blocks were smaller, but stacked higher, in more complicated and advanced structures, and more quickly.
In the end, the Greeks proved just how much more ambitious projects could be with the help of a crane. The Egyptian slaves responsible for building the pyramids block by ramp-elevated block are still squirming with envy in their graves.
Mobility and Versatility: Cranes Power the Roman Empire
Rome wasn’t built in a day, but without the introduction of and improvement upon the Greek cranes, construction would’ve taken much, much longer than it did. In fact, the Romans were the first to use multiple cranes for cooperative lifting tasks, as is evident by the massive cornerstone blocks used in some of the famous structures.
But beyond the beautiful, historic, crane-built city still very visible today, perhaps the most impressive aspect of Roman crane use was the way they were used far from their home. Again””necessity drives innovation. And as the Roman Empire stretched further and further away from Rome, and as conquering armies became more and more ambitious, mobility and versatility in their cranes became key. The Roman army needed cranes that could move quickly, be assembled and torn down quickly, and perform a variety of tasks””all without losing their powerful lifting capabilities.
Today, you can see that influence in how mobile cranes are used all over the world. You find them on boats, docks, trains, and trucks, often able to be quickly adapted for difficult, unusual tasks. Lifting capacity has skyrocketed, up to 1,000 tons. In the end, the Romans proved just how much mobility and versatility multiply capability.
At K&L Clutch, we understand just how many ways your business relies on your lifting capabilities. When a crane breaks down, we can be there””just about anywhere in the world””with the industrial machine parts to get your project back on track in no time.
Young MOC-8 heat exchanger
Our Young MOC-8 heat exchangers help maintain oil pressure, avoid air flow resistance, and keep your machines running at peak performance better than any others in the industry.
But beyond industrial machinery, heat exchangers play several vital roles in shaping our modern world, from industry to nature to our own, fragile bodies.
Here are three facts you might now know:
1. They’re used all over the place
Anything that needs highly optimized cooling and heating, really, as heat exchangers can reduce heat loss and redirect it to other purposes. Various types of heat exchangers are used in industrial sectors like power plants, petroleum refineries, and chemical plants. They keep jet fuel from freezing at high altitudes. They make up an important part of the wine production process. And they help keep waste water treatment plants operating at optimal temperatures, fostering the growth of microbes that remove pollutants from the water.
2. A similar system can be found in… birds, fish, and whales
Basically, arteries carrying warm blood to the skin get crossed and exchange heat with veins carrying cold blood away. The result is basically a “countercurrent” heat exchanger that reduces overall heat loss in cold waters””for baleen whales when the swallow enormous amounts of water to catch their evening krill, for storks, flamingos, and other wading birds when they stand in cool water, and for fish while breathing underwater.
No word yet if anybody has modeled an industrial machine after a blue whale.
3. We couldn’t live without them
Similarly, human bodies perform heat exchanger functions in two ways: Thanks to their large surface area, the lungs help moderate and optimize the hot or cold air we breathe in, before the oxygen is passed on into the blood stream.

At K&L Clutch, we supply only the highest quality torque converters. But to understand what this means, let’s start with the basics:
Torque converters are, of course, an automatic transmission’s answer to a manual transmission’s clutch””with one big advantageous twist (which we’ll get to below). Torque converters allow the engine to turn while a machine’s wheels and transmission gears come to a complete stop (think cars idling in a driveway).
More specifically, a hydraulic torque converter is a fluid coupling that lets an engine spin independently of a transmission.
To understand why this matters, think of a car in traffic. Keeping the car stopped at a stoplight takes just a light push on the brake, because there is only a tiny amount of torque being passed through the torque converter from the slowly turning engine or motor. But when you step on the gas, the engine roars and more torque is passed to the wheels. It’s basically a transfer of rotation power from any sort of internal combustion engine or electric motor to the driven object or load.
But here’s the twist “” hydraulic torque converters can actually multiply torque when there is enough of a difference between the rotational speeds of the engine and load, basically serving the same function as a reduction gear.
Hydraulic torque converters can be broken down into three basic parts:
Impeller “” The impeller (or the pump) is basically a ring of metal blades that are driven by the engine shaft, flinging fluid about in a manner similar to a washing machine, thereby imparting kinetic energy. The spinning also creates a vacuum, drawing even more fluid into the center.
Turbine “” The turbine is a set of three rings of blades connected to the shaft. The fluid from the impeller enters and turns the turbine and causes the transmission to spin, powering the machine.
Stator “” Located in the fluid circuit between rings of turbine blades, the stator (or reaction member) is made from two non-rotating sets of blades, contained in a stationary housing. The original fluid exits the turbine, moving in a different direction than when it came in (and in an opposite direction of the engine and pump spin). The stator keeps the fluid from hitting the pump, which would slow the engine.
Benefits:
· Longer Engine Life
· Longer Equipment Life
· More Efficient Fuel Economy
· Smoother Operation
· Better Shock Protection
· More Reliable Automatic Braking
· Faster Work Cycles
Hydraulic torque converters also have specific benefits that depend on your type of use.
For example, with slush pumps, hydraulic torque converters permit operation through a wide range of volume vs. pressure while using the maximum size liner. Crawler tractors can operate with maximum drawbar pull at all times, even in the roughest of operating conditions. Hoists and winches can hold loads in mid-air with the throttle alone, without bobbing. Shunting locomotives benefit from a good tractive effort curve. And in excavators, hydraulic torque converters deliver two to three times the amount of torque for hoist and crowd loads.
Check out our complete line of torque converters, or contact us for more information. We’ll tell you everything you need to know.
This great post has been a long lasting servant, and we recently decided to put out an update. Go ahead and read this too, though – It’s an oldie but a goodie!

Cranes are multi-faceted pieces of apparatus, and while they are capable of some quite incredible feats the way they actually work is based on some pretty straightforward laws of physics. Boom cranes are used to effectively and effortlessly lift heavy and/or awkward to move objects. The crane is most commonly used to hoist weighty equipment and/or materials on construction sites and to load cargo to ships. Read Full Article →

Dallas Cowboys fans got a glimpse of everything they were hoping to see Friday night. Their new stadium dazzled. Tony Romo was darn good. And the Cowboys won, pretty easily. In the first football game at the nearly $1.2 billion Cowboys Stadium, Romo looked right at home, going 18 of 24 for 192 yards and sending Dallas on its way to a 30-10 victory over the Tennessee Titans in a preseason game. “It was incredible,” Romo said, comparing the atmosphere to a regular-season game.
