Multistage Hydraulic Cylinder

Multistage hydraulic cylinder, also known as a telescopic hydraulic cylinder, consists of multiple nested stages (or sleeves) that extend sequentially to achieve a long stroke from a compact retracted length. Each stage operates under hydraulic pressure to extend, providing greater reach without increasing the overall size of the cylinder. Multistage cylinders can be single acting or double acting, depending on whether hydraulic pressure is applied in one or both directions. They are ideal for applications with limited mounting space and the need for long travel, such as dump trucks, lifting platforms, cranes, and refuse vehicles. Their design allows for smooth, controlled movement and efficient force transmission across multiple extension stages.
