What Is a Multistage Hydraulic Cylinder?
A multistage hydraulic cylinder (telescopic cylinder) uses several nested stages to achieve a long stroke while keeping the retracted length compact, ideal for dump trucks and heavy lifting equipment.
Cylinder Structure
A multistage cylinder is built from several nested tube stages. The largest stage is fixed to the machine frame, and smaller stages slide out one by one. Each stage has precision-honed tubes, seals, and guide rings to keep movement stable.
Where It Is Used
These cylinders are widely used on dump trucks, tipping trailers, garbage trucks, agricultural trailers and other equipment that needs long lifting height but limited installation space.
How It Works
When hydraulic oil flows into the base port, pressure first extends the largest stage. After it reaches full stroke, oil is routed internally to the next stage. Each stage extends in sequence, providing smooth and powerful lifting across the full stroke.
Multistage Cylinder Working Diagram
This working diagram shows how each stage of the multistage hydraulic cylinder extends, how the chambers are arranged, and how hydraulic oil flows through the system.

Working Principle
- Pressure oil enters from the base port and acts on the largest piston area first.
- The first stage extends until it reaches the mechanical stop at the end of its stroke.
- Internal passages then open to supply oil to the next stage in the sequence.
- Each stage extends one after another, giving a long and controlled lifting stroke.
Stage Chambers and Areas
- Every stage has its own pressure chamber and effective piston area.
- Larger stages offer higher lifting force at the beginning of the stroke.
- Smaller stages extend later, supporting higher lifting height at controlled load.
- The combination of different areas keeps lifting force and speed more stable.
Hydraulic Fluid Path
- Oil flows from the pump into the base port and is routed through internal drillings.
- Check valves and orifices guide oil into each stage chamber in the correct order.
- During retraction, oil returns through dedicated channels back to the tank.
- Proper flow control prevents knocking, reduces pressure spikes and protects the cylinder.

Frequently Asked Questions
Product-focused answers from a multi stage hydraulic cylinder supplier working with OEMs, fleets, and distributors.
What is the difference between 2-stage, 3-stage, 4-stage, and 5-stage cylinders?
The number of stages mainly affects lifting height and retracted length:
more stages give a longer stroke while keeping the closed length compact.
• 2–3 stages: often used on light-duty dump trailers and small trucks.
• 4–5 stages: common on standard dump trucks, grain tippers, and garbage trucks.
How do I choose the correct bore size and stroke for my machine?
Bore size is chosen according to your lifting pressure and payload. Stroke is decided by body length and required dumping angle. If you send us your truck model, body size, or old cylinder photos, our engineers can calculate a suitable bore and stroke for you.
What hydraulic oil types are compatible with your multistage cylinders?
Our cylinders work with common mineral-based hydraulic oils such as ISO VG32, VG46, and VG68. For low-temperature regions, we recommend low-viscosity oil and cold-resistant seal options. Tell us your working ambient temperature so we can suggest a suitable seal and oil combination.
Can your multistage cylinders match my existing pump, valve, and hose connections?
Yes. As long as we know your system working pressure, flow rate, and port thread type (BSP, NPT, or metric), we can design cylinders that fit your current hydraulic system. This reduces modification work on your truck or trailer.
Why does a telescopic cylinder sometimes knock or lift unevenly?
Typical reasons include air inside the system, contaminated oil, incorrect mounting angle, improper flow control, or seal wear on the first stages. We can provide a troubleshooting checklist based on the symptoms you describe.
How often should I maintain or replace seals in multistage cylinders?
Under normal working conditions, seal life is usually 1–3 years. For heavy-duty or dirty environments (mining, construction, sand, or chemicals), we advise more frequent inspection. We can supply seal kits together with each cylinder order.
Can you produce cylinders to replace an existing brand or model?
Yes. Many customers send us dimensions, drawings, or samples from their current brand. We then design a compatible cylinder with the same mounting, ports, and stroke, so you can switch supplier without changing the truck structure.
What is the usual working pressure range of your multistage cylinders?
Standard working pressure is typically 16–25 MPa, depending on bore size and design. For heavy-duty dump trucks or mining applications, we can design reinforced structures with higher safety factors according to your requirements.
Do you support custom colors, logos, and special mounting parts?
Yes. We can paint cylinders in your brand color, add laser logo or labels, and design custom mounting parts or brackets. This is helpful if you want to sell cylinders under your own brand.
How are cylinders protected and packed for international shipping?
Each cylinder is protected with plastic caps and rust-preventive oil, then wrapped and fixed on fumigation-free pallets. We provide packing photos and loading pictures before the container leaves our factory.
