Telescopic Hydraulic Cylinder

Telescopic Hydraulic Cylinder is a type of Hydraulic Cylinder that consists of multiple nested cylinders, with each cylinder gradually increasing in diameter to create a long stroke length while maintaining a relatively short retracted length. This design allows the cylinder to provide a long extension or retraction while using less space than a traditional single-stage cylinder.

Telescopic hydraulic cylinders are commonly used in applications where a long stroke length is required, but there is limited space available. They are often used in mobile equipment such as dump trucks, cranes, and excavators, where the equipment needs to be able to reach and lift heavy loads while operating in tight spaces.

Telescopic hydraulic cylinders can be single-acting or double-acting, depending on the application. In single-acting cylinders, hydraulic fluid is supplied to one end of the cylinder to extend it, while the weight of the load or a spring is used to retract the cylinder. In double-acting cylinders, hydraulic fluid is supplied to both ends of the cylinder to extend and retract it, which provides more control over the movement of the load.

Telescopic hydraulic cylinders are typically more expensive than traditional single-stage cylinders, but they are more efficient in terms of space usage and can provide a longer stroke length, making them a popular choice in many industrial and mobile equipment applications.
