For a lot of businesses, hydraulic systems make operations so much easier. It is more common than you might think and it’s what keeps these industries ticking. Hydraulic equipment isn’t limited to heavy machinery like ones on construction sites or the ‘movers’ on huge development projects. Firstly, hydraulics have the highest power density of any mechanical transmission system. It is also said that hydraulics will be around for a very long time (centuries to come) and that we will never stop needing them.
Hydraulic equipment has applications in different industries as some physical work can be accomplished in a simpler and safer manner using hydraulic equipment. Now, let’s take a look at the Top 5 industries that use hydraulic systems.
Automobile
Owning a car tells you that you use hydraulics everyday when you drive. Cars have hydraulic pumps, brakes, and motors to get you from point A to point B. Brakes utilize pressure applied on the brake fluid to press the pistons to brake pads. This allows you to stop.
Fun fact: The lowriders and hopping cars trend are because of hydraulics.
Indeed, the automotive industry not only makes extensive use of hydraulic systems but also utilizes hydraulics in both the manufacturing and finished phase as hydraulic pressure provides the power to trim, form, emboss, and make the major parts of an automobile. When manufacturing cars, machines mold sheets of metal into appropriate shape. A large set of hydraulic equipment is utilized during the manufacturing of automobiles because heavy components must be moved from one place to another, and this is one of the most ideal applications of hydraulics. Hydraulics make automobile manufacturing easier.
A car is completely assembled and is ready to roll off the assembly line. It will then include several distinct hydraulic systems necessary for operation. All repair shops that accomplish automobile repairs or servicing are actually equipped with a great deal of hydraulic lifts powerful enough to elevate a car that weigh thousands of pounds, so it can be worked on by a mechanic.
Being the largest users of hydraulics in the world, the automotive industry is actually the only industry that uses them for all manufacturing processes and also in the products they create like hydraulic systems creating smaller hydraulic systems such as car brakes. From manufacturing machines that make cars to garages/ small workshops that repair them, hydraulics are actually everywhere. Automobile as one of the industries that use hydraulic systems also utilize hydraulics for convertible roofs!
Aerospace
The aviation and aerospace are few of the industries that use hydraulic systems for several network of components on airplanes like takeoff and landing gears. These are also the industries that contribute billions to global GDP and utilize some of the most advanced technology. These are very heavy components which could only be retracted and positioned by using powerful hydraulics. Without hydraulic systems being used in airplanes, getting you to your chosen destination through air would be impossible; adjusting the wings or opening and closing doors would be impossible.
Take-off and landing gears are examples of hydraulic equipment that are equally as important. Hydraulics makes all this much easier and it accommodates the necessities of air travel quite nicely.
Now, the science behind Pascal’s Principle stating pressure on a fluid is equally distributed throughout fluid, is particularly useful for large units or pieces of equipment like the ones on planes. And systems can be included that are compact, lightweight, reliable and inexpensive-all ideal characteristics for those preparing to take to the air.
As a result, hydraulics are responsible in not only activating landing gear but also employing flaps and using brakes.
These basic aircraft systems include:
A pump to generate power
Actuating cylinders, which position components correctly
A heat exchanger to keep the hydraulic fluid at the correct and recommended temperature
A pressure relief valve to avoid dangers involving too much pressure
A reservoir to store the fluid
These components work together to ensure a plane’s inside components function safely and efficiently.
Construction
It’s very typical to see heavy equipment on a construction site as there are a great many heavy tasks that need to be accomplished and which can only be done by hydraulic-powered equipment. Bulldozers and backhoes are the best machinery to move large amounts of dirt and debris at the beginning of a construction project, and for stockpiling top soil. The driver pushes pushes on the soil allowing the shovel to lift heavy loads.
Without heavy machinery like bulldozers and backhoes, even small projects would take to finish.
To dig trenches for connecting sewer lines and water lines, backhoes are needed. They are also used for loading dump trucks full of gravel, dirt, and stone, so that they can be transported to desired locations. Imagine if there is no hydraulic equipment on a construction site, it could take weeks for workers to accomplish the same tasks which are routinely done in an hour or two by hydraulic-powered equipment. Indeed, large construction sites would not be possible without custom hydraulics. They are used in almost all large scale machinery.
Hydraulics are also used as props to hold up unstable walls or roofs. Hydraulics within the construction field is also used in brick molding machines, scissors lifts, concrete pumping, excavators, and more. The use of hydraulic systems transformed the construction industry allowing teams to complete assignments in less time and with less labor.
Agriculture
Agriculture is one of the industries that use hydraulic systems benefiting greatly by using hydraulic-powered equipment, and without it, a great deal of tasks which are necessary would take much longer to accomplish, and would require much additional manpower. Indeed, the food we eat takes dedication, long hours of work, and the proper equipment to make it to our plates.
One example of how crucial the usage of hydraulic equipment is in the three-point hitch, which is used for attaching accessories such as plows to a large tractor. And where would our farmers be (and our stomachs) without the beloved three-point hitch?
The three-point hitch includes hydraulic cylinders that make the movement of arms smoother so any accessory can be attached. The hydraulic cylinders in the hitch allow the arms to move properly so that the machinery can be attached. Tractors themselves are typically equipped with high-lift arms that facilitate loading silage into bins for cattle, and to accomplish a number of other critical tasks on the farm. Without the handy three-point hitch, countless amounts of time and effort would be wasted.
Entertainment
Have you seen the movie The Wicked Witch of the West? Well, she disappears in a puff of green smoke.
Yep, hydraulics.
Hydraulics have been used in the entertainment industry for literally everything from hidden platforms in stages or on sets to special effects. For instance, the 1976 version of King Kong relied tremendously on electro-hydraulics to accomplish all the movements of the monstrous ape as the star of the movie. And if you wondered how the Wicked Witch disappeared so quickly in The Wizard of Oz, the effect was achieved by her being lowered beneath the set by a hydraulic system, and as a puff of green smoke covered her disappearance.
Chances are, any movie which you have seen recently was made easier to film because it relied on hydraulic systems to manage and complete the filming. The mechanism which smoothly moves a camera around a set relies on hydraulics, so that it can position the camera close to the action. Also, a great deal of special effects which you normally see in movies are the result of custom-built hydraulic systems which operate behind-the-scenes. Entertainment is one of the industries that use hydraulic systems not only for filming but also for amusement parks and theatrical performances.
