Custom Telescopic Hydraulic Cylinder
Toleng custom telescopic hydraulic cylinders deliver exceptional stroke lengths in a compact retracted package. With multi-stage nested sleeve design, these cylinders extend to several times their retracted length — making them the ideal solution for dump trucks, hoist applications, and equipment where installation space is limited.

What Is a Custom Telescopic Hydraulic Cylinder?
A telescopic hydraulic cylinder, also known as a multi-stage cylinder, consists of multiple nested stages (sleeves) that extend sequentially. When hydraulic pressure is applied, the largest stage extends first, followed by each subsequent stage — providing a stroke length that can be several times the retracted length.
With a custom telescopic cylinder, you get a cylinder engineered to your exact specifications — custom number of stages, bore sizes, stroke lengths, mounting configurations, and pressure ratings. Extension ratios of up to 6:1 are achievable, making them ideal for applications where installation space is limited but maximum stroke is required.
Why Choose a Custom Telescopic Cylinder?
Telescopic cylinders offer unique advantages over standard cylinders
| Feature | Telescopic Cylinder | Standard Cylinder |
|---|---|---|
| Stroke Length | ✅ Up to 60 ft (18m) | Typically 1–20 ft |
| Retracted Length | ✅ Very compact — up to 6:1 ratio | Longer — limited by stroke |
| Extension Ratio | ✅ Up to 6:1 | ~2:1 max |
| Space Efficiency | ✅ Excellent — ideal for mobile equipment | Standard |
| Complexity | Higher — multiple stages | Simpler — single stage |
| Best For | Dump trucks, hoists, mobile equipment | Industrial, stationary applications |
Key Features
Why Toleng custom telescopic cylinders are the preferred choice for mobile applications
Multi-Stage Design
2 to 5 stages of nested sleeves provide smooth sequential extension for maximum stroke in a compact retracted length.
Exceptional Extension Ratio
Achieve up to 6:1 extension ratio — a cylinder that retracts to 10 feet can extend to 60 feet, maximizing stroke in minimal space.
Perfect for Mobile Equipment
Ideal for dump trucks, garbage trucks, trailer tippers, and agricultural equipment where installation space is constrained.
Single Acting & Double Acting
Available in single-acting (gravity return) for dump applications or double-acting for controlled extension and retraction.
Heavy-Duty Construction
High-strength steel sleeves, hard chrome plated surfaces, and premium seals ensure long service life in demanding conditions.
Customizable Options
Custom number of stages, bore sizes, stroke lengths, mounting configurations, and pressure ratings — engineered to your application.

Frequently Asked Questions
Quick answers about custom telescopic hydraulic cylinders
What is a telescopic hydraulic cylinder?
A telescopic hydraulic cylinder is a multi-stage cylinder with nested sleeves that extend sequentially, providing a very long stroke in a compact retracted length.
How does a telescopic cylinder work?
When hydraulic pressure is applied, the largest stage extends first, followed by each subsequent stage in sequence, providing a stroke length several times the retracted length.
What is the extension ratio?
Extension ratios of up to 6:1 are achievable — a cylinder that retracts to 10 feet can extend to 60 feet.
How many stages can a telescopic cylinder have?
Standard configurations range from 2 to 5 stages. Custom stage counts are available upon request.
What is the difference between single acting and double acting?
Single acting extends under hydraulic pressure and retracts by gravity. Double acting uses hydraulic pressure for both extension and retraction.
What applications use telescopic cylinders?
Dump trucks, garbage trucks, trailer tippers, hook loaders, agricultural equipment, and lifting platforms.
Can you customize mounting styles?
Yes, we offer clevis, cross-tube, trunnion, flange, and custom mounting configurations.
How long does the custom manufacturing process take?
Prototypes typically 2-4 weeks. Production runs 4-6 weeks. Expedited options available for urgent requirements.
What seals do Toleng telescopic cylinders use?
Premium polyurethane, nitrile, or Viton seals — temperature-specific options available.
What is the MOQ for custom telescopic cylinders?
We offer flexible MOQs — from single prototypes to high-volume production runs.
What certifications do you have?
ISO 9001 and ISO 14001 certified. 100% pressure testing on every cylinder before shipment.
Can you integrate sensors or valves?
Yes, we can integrate position sensors, counterbalance valves, and custom manifolds.
