Telescopic Hydraulic Cylinders

A reliable source for Telescopic Hydraulic Cylinders information and leading Telescopic Hydraulic Cylinders Companies & Manufacturers.

Telescopic hydraulic cylinders, also known as multi-stage cylinders, are linear actuators made of stacked sleeves on tubular rods. Four to five sleeves of shrinking diameters are stacked inside of one another. Hydraulic pressure can expand the largest sleeve (the main or barrel). Once the barrel has completed its full stroke, the following sleeve (called a stage) starts extending. This procedure repeats until the plunger, the cylinder’s final stage. The moment the cylinder’s pressure is released, the force of the load forces the oil out of the system, and the cylinder retracts. Read More…

Types of Telescopic Hydraulic Cylinders

Telescopic hydraulic cylinders are available in two varieties: single-acting and double-acting.

Single-Acting Telescopic Cylinders

In single-acting cylinders, retraction is initiated by gravity or external force. Single-acting telescopic cylinders are designed to extend with hydraulic pressure and retract with an outside force. They provide dependable, long-lasting performance and often have a wider outer diameter than rod cylinders. Single-acting telescopic cylinders are prevalent on dump trucks, platform trucks, and trailers.

Telescopic Hydraulic Cylinder

Double-Acting Telescopic Cylinders

Double-acting telescopic cylinders need hydraulic pressure to both extend and retract. They work well when horizontally mounted cylinders or other obstacles prevent gravity from assisting. Double-acting cylinders are frequently employed in transfer trailers, waste trucks, and non-critical positioning applications.

Double-Acting Telescopic Cylinder

Combination Telescopic Hydraulic Cylinders

Combination telescopic cylinders can be single-acting or double-acting. This means they’ll use hydraulic pressure for a portion of the stroke, then retract via gravity or external force. These multi-stage telescopic cylinders are used for heavy-duty applications like huge mobile drilling rigs. Hydraulic power is used more often than pneumatic telescopic cylinders when moving heavy weights. Telescopic hydraulic cylinders are used when extension starts from a small location because their collapsed length is 20 - 40% of the fully extended length. Combination telescopic cylinders use a longer working stroke than single-stage rod-style actuators. Dump trucks, elevators, and garbage trucks use telescopic cylinders.

Application Of Telescopic Cylinders

Pneumatic telescopic cylinders still exist, despite the prevalence of hydraulic power. Hydraulic power is more dependable for moving large weights. For example, a dump truck must tilt its load to a 60-degree angle to empty its contents. Hydraulic telescopic cylinders are a sensible option for this application.

Benefits Of Telescopic Hydraulic Cylinders

The telescopic hydraulic cylinder's small size, long stroke capacity, and ability to achieve specific angles are its main advantages. The hydraulic system is user-friendly and compact because it can retract.
