Product Description

HCIC high-performance hydraulic outrigger cylinder for concrete pump trucks and truck cranes. Bore 50mm-450mm, stroke up to 8000mm. Engineered for stability and safety in heavy construction.

Product Detail

HCIC hydraulic outrigger cylinders are custom made for pump trucks and mobile cranes. With 50–450mm bore and high-pressure resistance, they deliver stable load support. Hardened rods and premium seals ensure durable, drift-free performance on tough construction sites.

I. Ensuring Stability: The Role of the Hydraulic Outrigger Cylinder

In the world of heavy construction, stability is not just a feature—it is a life-saving requirement. When a concrete pump truck extends its boom over 50 meters, the lateral forces on the chassis are massive. The hydraulic outrigger cylinder is the core component that carries this load, anchoring the machine to the ground and preventing catastrophic rollovers.

At HCIC, we specialize in the "big three" of pump truck hydraulics: boom cylinders, pumping cylinders, and outrigger cylinders. Our Hydraulic Outrigger Cylinder is engineered to provide absolute rigidity under high-tonnage static loads, ensuring that your operators can work with confidence on any job site.

II. Technical Specifications

These parameters represent the manufacturing range for our engineering machinery series, verified against the HCIC 2026 technical standards:

Parameter	Specification Range
Bore Diameter	50mm - 450mm
Rod Diameter	32mm - 280mm
Maximum Stroke	Up to 8,000mm
Rated Pressure	25 MPa - 35 MPa
Cylinder Material	ST52-3 / 45# Steel / 20# Steel
Piston Rod Treatment	Hard Chrome Plated / QPQ Nitrided
Seal Package	High-pressure Polyurethane (Hallite/Parker equivalent)

The wide bore range (up to 450mm) allows our hydraulic outrigger cylinder to be matched to equipment ranging from small truck-mounted cranes to the largest concrete pump trucks in the industry.

III. Engineering for Safety and Longevity

3.1 Load-Holding Integrity

The most critical failure for an outrigger is "drift"—where the cylinder slowly retracts under load. To prevent this, every **Hydraulic Outrigger Cylinder** we build is designed to integrate perfectly with pilot-operated check valves or counterbalance valves. This creates a redundant hydraulic lock, ensuring the outrigger stays exactly where the operator set it for the duration of the pour.

3.2 Advanced Surface Protection

Outriggers work in the dirt, mud, and concrete splatter of the construction site. Our piston rods undergo a rigorous treatment process:

- Induction Hardening: To resist mechanical impact from flying debris.

- Hard Chrome Plating: 30-50 microns of plating for superior wear resistance.

- Corrosion Resistance: Salt spray testing to ASTM B117 standards to ensure long-term durability in outdoor environments.

3.3 Precision Welding and Honing

We utilize automated robotic welding to ensure 100% penetration on mounting lugs and ports. The barrel interiors are honed to a 0.2-0.4μm Ra finish, reducing internal friction and heat buildup during deployment.

IV. Application Scenarios

- Concrete Pump Trucks: Front and rear outrigger systems for stability during pumping.

- Truck-Mounted Cranes: Rapid deployment legs for load handling.

- Aerial Work Platforms: Stabilizing jacks for high-altitude maintenance vehicles.

- Drilling Rigs: Leveling cylinders for mobile drilling platforms.

V. FAQ

Are your outrigger cylinders compatible with brands like Putzmeister or Schwing?

Yes. The Hydraulic Outrigger Cylinder from HCIC is designed to be a direct‑fit or OEM‑equivalent for mainstream global brands. We can build to your exact pin‑to‑pin and port specifications.

Can you provide cylinders with integrated valves?

Absolutely. We can machine the cylinder head to accept counterbalance valves or supply a complete manifold assembly as part of the package.

What is the maximum load capacity for the 450mm bore model?

Depending on the system pressure (up to 35 MPa), our largest Hydraulic Outrigger Cylinder can support static loads exceeding 500 tons.
