Hydraulic Telescopic Cylinder

Dump Truck Hydraulic Telescopic Cylinder

Cylinder Barrel: The external housing is made of high-tensile steel that accommodates the internal components and withstands the internal pressure.

Telescopic Piston Rods: Multi-stage, concentrically nested rods that provide extended linear motion from a compact retracted length.

Piston Assembly: The actuating component situated within the barrel, is responsible for converting hydraulic energy into mechanical force.

Sealing Mechanisms: Comprising O-rings, wiper seals, and rod seals, these elements prevent fluid leakage and ingress of contaminants.

Hydraulic Ports: The apertures for fluid ingress and egress, usually designed as threaded or flanged connections for hydraulic lines.

Rod Bushings: These are wear-resistant guides that stabilize the piston rod’s linear movement and absorb transverse forces.


Dump truck hydraulic telescopic cylinders offer a comprehensive set of advantages tailored for heavy-duty applications. Their adaptive stroke length, facilitated by a multi-stage telescopic mechanism, allows for versatile dumping heights, making them incredibly adaptable. Engineered to tolerate high hydraulic pressures, they are ideal for tasks requiring significant lifting forces. Additionally, their corrosion-resistant coatings ensure durability in harsh conditions. Moreover, their single-acting design enhances energy efficiency by requiring less hydraulic fluid. All these attributes combine to make these cylinders a reliable, versatile, and cost-effective solution for a wide range of demanding tasks.


Bulk Material Handling: Ideal for transporting and unloading large volumes of materials like gravel, soil, or waste.

Heavy Construction: Frequently used in construction equipment for tasks like earthmoving or debris removal.

Industrial Use: Employed in various industrial settings for tasks that require lifting, tilting, or dumping of heavy loads.

Emergency Services: Some versions are used in fire trucks and rescue vehicles for extending ladders or stabilizing platforms.


Adaptive Stroke Length: The multi-stage telescopic mechanism allows for variable stroke lengths, providing flexibility in dumping heights.

High-Pressure Tolerance: These cylinders are engineered to withstand elevated hydraulic pressures, making them well-suited for applications that demand high lifting forces.

Corrosion Resistance: Specialized coatings and finishes provide excellent resistance to corrosion, extending the cylinder’s lifespan.

Safety Measures: Built-in safety features like velocity fuses and load-holding valves offer an added layer of protection, preventing accidental descents in the event of hydraulic failure.
