Hydraulic telescopic cylinders are in trend. Many heavy-duty machines and lifters use these cylinders. Almost all modern lifters, dumper trucks, and trailers rely on them for the best output. There are many advantages of hydraulic telescopic cylinders. Numerous people consider them similar to normal hydraulic cylinders.
But that’s not true. These telescopic cylinders are unique in many ways, not just in their appearance but also in their functionality. This uniqueness makes them very popular for more heavy-duty machines. Do you want to know WHY? Read this article as I’ll explain the reason for their popularity.
Is Telescopic Similar to Normal Hydraulic Cylinders?
The answer is NO! These cylinders are more like telescopes. They have nested sections or stages that remain inside each other. Each section has its unique cylinder and piston. They extend when hydraulic fluid fills the cylinders. What makes them stand out is their long stroke.
Regular cylinders consist of a barrel and rod. They have one cylinder that uses fluid to push the piston outward. They don’t have any sections or stages. On the contrary, the telescopic cylinders are different. They consist of multiple sections of stages that use their cylinders. The fluid fills each of those cylinders.
What makes them popular is their extension of sections once filled with fluid. They are more expensive than regular cylinders and offer more perks. Their high price is because of those multiple sections. Hydraulic telescopic cylinders can have two, three, or even four sections or stages. Four-stage cylinders will offer a longer extension and vice versa.
Benefits of Hydraulic Telescopic Cylinders
The purpose of the above section was to give a basic know-how of this type of hydraulic cylinder. Let’s go and discuss the different advantages of telescopic cylinders.
1- Long Stroke
As I said, the telescopic cylinders consist of multiple sections. Each section or stage remains nested over each other when not in use. However, when the fluid goes into their cylinders, they extend. Why? Because hydraulic fluid exerts pressure on their piston. Due to this extension, they offer long extensions or strokes.
Due to the long stroke, these cylinders can easily lift the truck’s bed to some height. Have you ever seen a spider lift? Workers use them to reach high points in compact space. Those lifts also use these cylinders. The section of these cylinders extends and takes the lift to a high position. This is the best example of how these cylinders provide a long stroke.
2- Take Less Space
These telescopic cylinders sound like they are bulkier. Right? But interestingly, they occupy very little space. Let me explain how. These sections remain nested over one another. For example, a telescopic cylinder has three stages.
The last two stages would be nested in the first section. They will only extend when the fluid goes inside them. These telescopic cylinders can also be used in machines that are not bulky. They will easily fit in a small space. However, when activated, they will extend and do their job.
3- Specific Angle Requirements
These cylinders are suitable for achieving different-angle lifts. Sometimes, you need to lift something at a particular angle, correct? The dump trucks unload by lifting the truck’s bed at a 50-degree angle. Moreover, the loaded trolley attached to the tractor also lifts at this angle.
In these cases, these cylinders work their magic. Once the fluid comes, press the piston, and the sections extend out. The setup of the cylinder is so that the extension of the section officer lists the bed or trolley at an angle. This lifting helps to unload material quickly. Without this, unloading from the trolley would have been a tedious job.
4- Smooth Operation
The workings of the telescopic hydraulic cylinder are very smooth. The section extends smoothly and doesn’t give any thrust. Let me explain this in simple words. These cylinders use hydraulic fluid. First, the fluid enters the first cylinder and fills it. There remains a check valve in each cylinder of this system.
Once the first cylinder is filled, the fluid goes to the second cylinder. In the meantime, the first start was extended due to fluid pressure. After filling the second cylinder, the check valve allows fluid to enter the third cylinder. The second section starts to extend smoothly as it is filled with fluid. The pressure of fluid extends.
This filling of the cylinder goes in sequence. As a result, the section’s extension is very smooth. Remember, hydraulic fluid pushes pressure on the cylinder that extends the section. Once the job is done, the fluids move back in sequence. The section’s retraction also happens in the proper sequence. Their retraction does not jerk the truck’s bed as well.
5- High Lifting Force
The telescopic hydraulic cylinders are mighty. The extended stages can help complete any heavy-duty task. For example, you can lift, press, and push. There are no restrictions. This is because these cylinders and their sections offer excellent power output.
Due to their power, these cylinders are used in heavy-duty machines. Moreover, three types of these cylinders are available, each offering unique value. For example, the single-acting telescopic cylinder is inexpensive. On the flip side, the double-acting cylinder provides more utility and ease of operation.
However, these cylinders are a bit more expensive. You can even get a combination of single-acting and double-acting cylinders. All these types offer excellent power, but their pricing varies from each other. The purpose of explaining this is that these cylinders are versatile. They can quickly fulfill your needs.
When to Consider a Telescopic Hydraulic Cylinder?
As I said earlier, these hydraulic cylinders are versatile. You can use them on any machine to achieve any secific functionality—there is no limit. However, people prefer them for lifting tasks. Almost all trucks and trollies come with these cylinders. The reason is that they give excellent long strokes and extensions.
The stages of these cylinders extend and lift some to higher heights. I have given many examples in the above section. Many construction and agricultural machines rely on them. Have you seen rescue teams using lifters to reach high buildings and rescue people in an emergency case? Those lifters also use these cylinders.
Quick Highlight: Hydraulic Cylinders are generally used for lifting, pressing, carrying, and pushing. These telescopic cylinders can be used for any of these tasks. However, they work like a charm when it comes to lifting. Their multiple stages can easily lift any object at some height.
Conclusion
Hydraulic telescopic cylinders are excellent in terms of power. They can offer excellent lifting functionality in different machines and equipment. You get so many benefits when using these telescopic cylinders. However, I’ve explained the most important of those. The purpose of this guide was to explain the reason for their popularity. Among all the reasons, the long stroke is the most prominent that makes them stand out.
