What Do You Mean by Telescopic Cylinders?

Telescopic cylinders are normally used for applications where a normal cylinder would not have enough space to extend. They are much more expensive than normal cylinders since they require more construction materials and a specialized design. They are only used for hydraulic applications.

The models currently on the market are manufactured with up to five stages and 5 hubs. The largest bushing extends first, then the second largest bushing, and so on. Each bushing is smaller than the previous one. For this reason, the force of the cylinder increases, and the speed increases each time the cylinder passes to the next stage.

This type of cylinder is integrated into the phases where the effect of the piston expands over several barrels, which fit perfectly into the main sleeve of reduced size. Telescopic Cylinders Suppliers provide a wide range of cylinders for your industry.

Since most telescopic hydraulic cylinders are mounted on a sleeve, representing almost 20% of the actual working length, they offer a larger working stroke. If a conventional single-rod hydraulic cylinder cannot be used, a telescopic hydraulic cylinder will be preferred due to its compact size.

Telescopic Cylinders work on a similar principle to single and double-acting hydraulic cylinders. The main difference between the two types is that, in telescopic cylinders, the piston or barrel is integrated with a compact housing with other tubes, which extend along with the extension of the main piston or barrel.

Telescopic hydraulic cylinder applications

A simple rod system will suffice for most equipment requiring hydraulic cylinders as they are less complex and very reliable. However, in some situations, it will be necessary to use telescopic hydraulic cylinders, depending on the application. For good quality cylinders, you can contact Telescopic Cylinders manufacturer.

Telescopic hydraulic cylinders offer more strokes in a compact size. The long stroke, in combination with the size, is very useful when the work surface on a vehicle or machine is very small. Although single-rod hydraulic cylinders can be used in most cases, here are some applications of telescopic hydraulic cylinders:

Garbage trucks

It is the most common use of telescopic hydraulic cylinders. During unloading, a garbage truck must reach an angle of 60 degrees. A normal cylinder cannot do this, as it would require an extremely long rod to complete the task, which is very expensive to implement.

Single Acting Hydraulic Cylinders are ideal for dump trucks as the vertical movement allows for smooth retraction. Double-acting hydraulic cylinders can be used with horizontal movements, although retraction force must be applied.

Construction Equipment

Telescopic hydraulic cylinders can also be installed on construction equipment. Thanks to them, cranes can be extended horizontally to move heavy loads, while excavation vehicles can reach greater depths.

Oil rigs

These locations use a single rod and telescoping hydraulic cylinders. To do this, they create a hybrid by combining both types. Since offshore oil rigs are located in small spaces, telescopic hydraulic cylinders save space and improve performance over single-rod cylinders.

Other uses

Window cleaning lift systems use telescopic hydraulic cylinders. When a fixed height is reached with the metal frame structure, the cylinders extend the top a bit more.
