The construction industry generates a sizeable demand for telescoping hydraulic cylinders. Heavy equipment such as dump trucks and other large back-end loaders require the ability to lift its load high enough to empty gravel, sand or other materials that are used to erect buildings. The agricultural and waste management industries also use telescopic hydraulic cylinders. They are not always easy to spot, as their location requires them to be angled, often buried within the equipment load. They have many uses and show up on all kinds of equipment.

Hydraulic Fluid and Gravity
There are two basic designs for a telescopic cylinder, single and double acting. A single acting model is the most common with a single steel rod style cylinder. The hydraulic pressure extends the telescopic cylinder and it retracts when the hydraulic fluid is removed to a reservoir. Retraction also gets some added help from gravity pressing down on the load.
Six Degrees of Separation
The key design feature of a telescoping hydraulic cylinder is its ability to provide an exceptional long stroke from its initial compact stage. There is a 20 to 40% extension rate and in the retracted position it requires a much smaller space making the system a smart engineered product. As the name implies, the telescopic cylinder is made up of sections of steel tubing and each section is referred to as a stage. The small stage can also be referred to as the plunger. The design of a telescopic cylinder is usually restricted to 6 extendable stages for the sake of stability. When the cylinder is engaged it normally extends from the largest to the smallest stage. It contracts in the opposite direction.
Standard vs. Customized
There are commercial manufacturers with inventory stock, such as the crosstube telescope hydraulic cylinder. A cylinder manufacture will gladly work with you to engineer a design and build to specifications. If you are considering a customize telescoping hydraulic cylinder be sure to check on the date of delivery. Like any component manufacturer special design orders, can delay delivery, although they can usually offer you options for express service at an added cost.
