Telescopic Hydraulic Cylinder for Dump Trailer

The cylinder consists of multiple tubes, called stages, nested within one another. Each stage is a cylinder, with its own piston and sealing elements.

Piston and Seals
Each stage has a piston attached to its base, and the piston moves within the cylinder stage to extend or retract it. High-quality seals prevent any hydraulic fluid leakage between the stages and between the piston and the cylinder wall.

Hydraulic fluid is supplied to the cylinder through ports, usually located at the base of the outermost stage. The fluid pushes the pistons, causing the cylinder to extend.

The cylinder is typically made of high-strength steel for durability and to withstand the high pressures encountered during operation.

Various mounting options are available, such as trunnion mounts, clevis mounts, or direct mounts, to suit different dump truck configurations.


A telescopic hydraulic cylinder is a specialized type of hydraulic cylinder designed for applications that require a long stroke length while maintaining a compact retracted size. This makes it particularly well-suited for dump trailers, which often need to lift heavy loads over a significant distance but have limited space for equipment.


Dump Trailers
The primary application is in dump trailers used in construction, waste management, and material handling industries.

Agricultural Equipment
In the agricultural sector, these cylinders are used in equipment like grain trailers to facilitate the efficient unloading of produce.

Mining Operations
In mining, they are used in off-road dump trucks and other heavy machinery to manage the movement of earth and ore.

Material Handling
In warehouses and docks, telescopic hydraulic cylinders can be used in lifting equipment to manage heavy or bulky loads over a vertical distance.

Specialized Vehicles
They are also found in specialized vehicles like fire trucks and rescue vehicles, where space is limited but a long reach is required.


Space Efficiency
The telescopic design allows for a long stroke length while maintaining a compact retracted size. This is crucial for dump trailers where space is often limited.

High Lifting Capacity
These cylinders are designed to handle heavy loads, making them ideal for lifting the large and often uneven loads commonly found in dump trailers.

The various mounting options, such as trunnion mounts, clevis mounts, or direct mounts, make it adaptable to different dump trailer configurations.
