The Greatest Advantage Of Telescopic Cylinder

The biggest advantage of telescopic cylinder is that it can provide ultra-long stroke from a compact initial package. The folded length of a typical telescopic cylinder varies from 20% to 40% of its extended length. Therefore, when the installation space is limited and the application needs a long stroke, the telescopic cylinder is a reasonable solution.
For example, suppose that the dump body needs to be tilted 60 degrees in order to completely empty. If the body or trailer is equipped with a traditional rod cylinder (with an integral cylinder, with a stroke long enough to reach the angle), the dump body cannot return to the horizontal direction of road travel even if it is fully retracted due to the length of the cylinder. The telescopic cylinder can easily solve this problem.
Telescopic hydraulic cylinders are relatively simple devices, but their successful application requires understanding the characteristics of these components. Understanding the working principle of telescopic cylinder and the special application standards that need to be considered will enable you to design it into equipment safely and economically.
Main stage
As the name implies, the structure of telescopic cylinder is like a telescope. Steel pipe segments with smaller diameters are nested with each other. The part with the largest diameter is called cylinder barrel; The moving part with smaller diameter is called stage; The smallest stage is also known as the plunger. The maximum actual number of mobile stations seems to be 6. Theoretically, more cylinders can be designed, but their stability will be daunting.
The telescopic cylinder usually extends from the largest stage to the smallest stage. This means that the largest stage - all the smaller stages nested inside - will move first and complete its journey before the next stage starts moving. This procedure will continue at each stage until the minimum diameter stage is fully extended. Conversely, when retracted, the smallest diameter stage will fully retract before the next stage starts to move
