4 Stage Hydraulic Cylinder for Dump Truck

Nested Barrels: It features four barrels, each progressively smaller and nested within the other, enabling a significant extension range.

Piston Rods: Each barrel contains a piston rod, crucial for the push-pull action of the cylinder.

Pistons: The pistons, located within the barrels, are essential for creating the hydraulic force needed for movement.

Sealing System: High-quality seals are used in each stage to prevent fluid leakage and maintain hydraulic pressure.

Mounting Brackets: Robust mounting brackets at each end of the cylinder ensure secure attachment to the dump truck.

Ports: These ports allow for the flow of hydraulic fluid into and out of the cylinder, controlling its extension and retraction.

External Housing: A sturdy external housing protects the inner components from external elements and damage.


The 4 stage hydraulic cylinder for dump truck is designed to meet the rigorous demands of lifting and dumping large loads. Its four-stage design allows it to extend farther than standard cylinders. When retracted, it is extremely compact, saving valuable space in truck designs.

The telescopic cylinder utilizes hydraulics to extend and retract, providing powerful and smooth operation. In essence, it combines reach, strength and compact design to meet the challenging requirements of dumping operations.


Extended Reach: Its four-stage design allows for a significantly longer extension, perfect for reaching higher dump heights.

Space Efficiency: When retracted, it’s impressively compact, saving valuable space in the truck’s design.

High Lifting Capacity: Capable of lifting heavy loads, it’s ideal for moving large volumes of material.

Durable Design: Built to endure tough conditions, it’s reliable for consistent, heavy use.

Smooth Operation: Ensures controlled and stable movement, crucial for safe dumping operations.

Easy Maintenance: Designed for ease of service, prolonging its lifespan and efficiency.


Construction Sites: For dumping building materials like sand, gravel, and debris.
