In the world of hydraulic equipment, there are different classification systems. If you consider the diverse types and typology, you will arrive, eventually at classification according to specification. In this list, besides Plunger (Ram), Cable or Diaphragm hydraulic cylinders, you will find one interesting and unique kind. It is the telescoping hydraulic cylinder. This is a type that is called upon in the industry by those who have limited space.
Characteristics of the Telescoping Hydraulic Cylinder
The telescoping hydraulic cylinder is a type of what is called an actuator. It is sometimes referred to as:
1. A multistage hydraulic cylinder
2. Telescopic hydraulic cylinder
Whatever the nomenclature, this classification of hydraulic cylinders has distinguishing characteristics. The most overt is because the name of this device. They are telescopic in nature. In other words, their cylindrical rods called stages or sleeves are telescopic in nature that act to extend the overall length of the hydraulic cylinder. This hydraulic series of tube-shaped rods nestle one within the other in increasingly smaller size. They can extend or contract as required. At most, the stages or sleeves are numbered a total of six. More frequently they number four or five.
In action, the telescoping hydraulic cylinder can be either single acting or double acting. Some companies specialize in only one version. Others produce both types. However, single acting telescoping hydraulic cylinders are far more common than the double acting type. The resulting stroke of this classification of hydraulic cylinder, whether single or double acting, is long. This makes it very suitable for certain practical applications.
The Actions of a Telescoping Hydraulic Cylinder
The action within a telescoping hydraulic cylinder begins when the hydraulic pressure is introduced. The first extension takes place. This is the largest sleeve or barrel, also called the main. Once the barrel has reached full extension or stroke, the next sleeve, now called a stage begins to stretch out. The entire process repeats itself until the telescoping hydraulic cylinder has become fully extended. In this process, the final stage is referred to as the plunger. The retraction process does not occur until the applied force of the load of the telescoping hydraulic cylinder pushes the oil out of the cylinder.
Applications of a Telescoping Hydraulic Cylinder
Those who prefer a telescoping hydraulic cylinder do so for any of several reasons. The major incentive for its use relates directly to its telescopic ability. If a cylinder can expand and contract, it can fitted to perform in confined or smaller spaces. Although in a relatively small package it can execute a very long stroke. The initially innocuous appearing and compact cylinder can extend and perform a very limited mounting space where other types of hydraulic cylinders cannot. As a result, industries which produce garbage trucks, dump trucks and lifts all rely on the power and capabilities of the telescoping hydraulic cylinder to get the work done.
