1. Comprehensive Product Overview
The EPYY11112006 AWP Lifting Cylinder represents the pinnacle of high-reach hydraulic power. As a primary Aerial Work Platform Hydraulic Cylinder, its job is to bear the foundational weight of the boom and personnel basket, elevating them seamlessly to peak operational heights. Designed as a premium aftermarket replacement, it offers true 100% mechanical compatibility with heavy-duty lift models from global OEMs including JLG, Genie, Manitou, Skyjack, and Haulotte.
Target Industry Applications:
- Infrastructure Construction: Primary elevation for high-reach articulating and telescopic boom lifts on mega-sites.
- Bridge & Highway Maintenance: Stable lifting against extreme wind sheer and uneven road cambers.
- Aviation & Shipbuilding: Long-stroke vertical access for massive fuselage and hull painting.
- Heavy Industrial Plants: Unyielding lifting force for heavy material and personnel transport.
Core Advantage Summary: What sets the EPYY11112006 apart is its integrated heavy-duty base mounting flange combined with a massive 1260mm stroke. Weighing in at 54kg, this Hydraulic Lift Ram diffuses extreme compressive loads across a wider chassis footprint, preventing structural fatigue while maintaining a 27MPa burst-proof safety margin.

3. Working Principle & Structural Blueprint
The EPYY11112006 functions as the primary double-acting Lifting Cylinder for mega-reach aerial platforms. Due to its massive 1260mm extension capability, the physical laws governing its operation require exceptional structural integrity to prevent buckling or bending.
Operational Dynamics: When the operator engages the lift controls, hydraulic fluid at 18MPa fills the base chamber, exerting tremendous force across the Φ65mm piston face. This extends the thick Φ45mm rod upward. A counterbalance (load-holding) valve is typically integrated into the circuit, trapping fluid in the cylinder to ensure the boom cannot drop in the event of a power loss or hose rupture.
Flange-Mount Blueprint Anatomy: The provided CAD drawing reveals a unique and highly critical structural feature: a massive square mounting flange integrated at the base of the cylinder body. Instead of a single pivot pin at the bottom, this flange uses a 4-bolt pattern to anchor the 1629mm cylinder solidly to the AWP chassis. This rigid mounting style drastically reduces side-loading and evenly distributes the immense downward force of the boom across the machine’s frame.

4. Core Advantages of EPYY Lifting Rams
Extra-Long 1260mm Stroke
Designed specifically for high-reach AWPs. The massive 1260mm continuous extension allows articulation booms to achieve maximum working height smoothly, reducing the need for multiple staged cylinders.
Rigid Flange Mounting
Unlike standard pin-eye bases, the heavy-duty square flange distributes compressive forces over a wide area of the chassis, offering unparalleled rigidity and eliminating base-wobble during operation.
27MPa Shock Resistance
A 54kg solid steel build grants this cylinder an immense 27MPa burst rating. It safely absorbs severe hydraulic shock loading caused by wind gusts or sudden emergency braking.
Zero-Drift NOK Sealing
Utilizing an imported Japanese NOK polyurethane sealing matrix, the EPYY11112006 prevents internal fluid bypass. Your boom stays perfectly locked at altitude, eliminating dangerous creeping.
Anti-Buckling Φ45mm Rod
Pushing a load up 1.26 meters creates immense columnar stress. The oversized Φ45mm piston rod is specifically designed to resist buckling and bending under maximum compression.
5. Structure and Material Craftsmanship
As a globally trusted Aerial Work Platform Cylinder Manufacturer, we recognize that a 54kg lifting ram is the backbone of your equipment. We utilize uncompromised metallurgical standards to guarantee decades of service life.
The main cylinder barrel is CNC machined from ST52.3 (E355) high-yield seamless steel. To protect the high-pressure seals over the massive 1260mm stroke length, the interior bore is skived and roller-burnished to a mirror finish of Ra 0.2µm, virtually eliminating friction-induced heat and seal degradation.
- Induction Hardened Rod: The Φ45 rod is forged from 45# carbon steel, deep-induction quenched for impact resistance, and coated in 30-50µm of hard chrome to repel concrete dust and maritime salt spray.
- Robotic Flange Welding: The critical base mounting flange is fused to the barrel using multi-pass, automated robotic TIG welding. Every weld undergoes ultrasonic non-destructive testing (NDT) to ensure zero porosity.
- 100% Load Testing: Prior to shipping, every EPYY11112006 undergoes a strict 27MPa hydrostatic pressure test to guarantee structural integrity.

6. Typical Aerial Application Scenarios
🏗️ Infrastructure Construction
Building highway overpasses and bridges requires massive boom lifts. The EPYY11112006’s 1260mm extension capability pushes articulation arms high enough to clear massive concrete pillars safely and steadily.
🚢 Shipbuilding & Drydocks
Scaling the sides of cargo vessels requires unwavering vertical lift. The rigid flange mount ensures that even when fully extended at 18MPa, the platform does not wobble against maritime crosswinds.
🏙️ High-Rise Maintenance
Used in the base lifting mechanism of large truck-mounted AWPs. The anti-buckling Φ45mm rod guarantees that two operators and their heavy tools can be elevated simultaneously without structural deflection.
