Enjue Intelligent Mechanical Over Height Spreader: A "Transformer" for Heavy-Duty Loading and Unloading. In the busy ports, facing increasingly diverse cargo transportation demands, the key to improving operational efficiency lies in quickly accommodating oversized cargo and various special containers without changing spreader equipment. The Enjue Overheight spreaders, a mechanical extension unit designed specifically for extreme conditions, stand as a "golden bridge" connecting port spreader equipment and unconventional cargo thanks to their superior load-bearing capacity, fully mechanical synchronous linkage design, and extreme durability.
Heavy-duty DNA, Born for Extreme Working Conditions
The Enjue over height spreaders are not just a simple physical extension, but a highly integrated mechanical solution. It is specifically designed to match ZPMC (Zhenhua Heavy Industries) and SANY (Sany Heavy Industry) container spreaders, perfectly adapting to the highest frequency of operations at the terminal.
Key Performance Specifications:
Rated Lifting Capacity: Capable of stably supporting up to 40 tons of cargo (L3 load condition) under the spreader, handling even fully loaded heavy flatbeds or oversized cargo with ease.
Operating Class: Designed to meet M6 working class standards, meaning it can withstand high-frequency, high-intensity continuous operation, ensuring stable and reliable performance throughout its lifespan.
Effective Clearance: Provides ≥2 meters of vertical lifting space, ensuring sufficient safe operating distance between the spreader and the container top when loading and unloading oversized cargo.
Fully Mechanical Linkage: An Intelligent "Body" Without Power
The Enjue over height spreaders pursue ultimate purity and reliability in their design philosophy. It abandons complex hydraulic lines and electronic components, returning to the essence of mechanical transmission.
Synchronous Extension and Retraction & Locking: The elevated frame itself has no power source. Its core actions-the 20/40/45-foot extension/retraction adjustment and the locking/unlocking of the pivot pins-rely entirely on physical linkage with the spreading gear. The rotation of the spreading gear's pivot pins is converted into the synchronous passive opening and closing of the pivot pins at the bottom of the elevated frame through a precisely designed pivot pin sleeve and linkage mechanism.
This design achieves smooth operation where "when the spreading gear moves, the elevated frame responds," greatly reducing the failure rate.
Anti-Disengagement Auxiliary Connection Mechanism: To mitigate the risk of inadvertent loosening during high-intensity operations, anti-disengagement hooks are ingeniously incorporated on both flanks, achieving a flawless fit with the lifting hook. Upon connection of the main pivot pin, these hooks are securely locked in place, guaranteeing a seamless integration between the lifting apparatus and the overhead frame, thereby effectively eliminating latent safety risks.
In the face of extreme environmental temperature fluctuations, ranging from a frigid -40°C to a scorching +55°C, coupled with the corrosive onslaught of high-salt marine spray and relentless heavy-load impacts, the Enjue super-elevated frame undergoes an exceptionally rigorous material selection process.
Structural Robustness: The primary framework is constructed from Q235 steel, whereas all pivotal load-bearing elements, including beams and corner joints, have been upgraded to Q345 low-alloy high-strength steel. This strategic choice ensures a lightweight design, tipping the scales at a mere 2.1 tons, while simultaneously delivering outstanding torsional and bending resistance.
Surface Protection (Marine-Grade Anti-Corrosion Measures): Adheres to the most stringent corrosion protection standards set forth for port machinery, specifically JT/T 733-2008.
Coating System: Employs Hemmpel paints or an equivalent brand, ensuring long-lasting protection against the elements.
Three-Layer Protection: Epoxy zinc-rich primer (≥50μm) provides cathodic protection; epoxy micaceous iron oxide intermediate coat (≥150μm) forms a shielding layer; polyurethane topcoat (RAL1003 yellow, ≥100μm) provides weather and UV resistance. Total film thickness: The total dry film thickness of the coating is not less than 300μm, which is like putting a thick anti-corrosion armor on the steel structure, so as to cope with the challenges of marine transportation and open storage.
Enjue understands that high-performance equipment must be easy to maintain. Therefore, we incorporated numerous human-centered considerations into the details:
Easy Maintenance Design: All lubrication points are equipped with PT1/4" stainless steel flat-head (button-type) grease fittings, allowing workers to easily add grease with one hand. Sliding surfaces, support surfaces, and other vulnerable parts are designed for quick disassembly and assembly, and are equipped with anti-loosening measures.
High-Standard Fasteners: Bolts and nuts smaller than M12 are all made of A4-70 stainless steel, providing rust and corrosion resistance; fasteners larger than M12 undergo Dacromet coating treatment, ensuring no risk of hydrogen embrittlement under high-strength preload and significantly increasing durability.
Personnel and Handling Convenience:
Personnel Capacity: The structural design includes interfaces for personnel work platforms, meeting the needs of high-altitude maintenance under special working conditions.
Forklift Fork Holes: Standard forklift fork holes are provided at the bottom for easy internal warehouse transport.
Landsweeper Lifting: When relocation is required, the high-reach crane can be fixedly connected to a dedicated base frame for direct lifting and transport by a front-reach crane, enabling rapid site switching.
Enjue mechanical over-height spreaders – more than just an extension of lifting equipment, they expand the boundaries of your operational efficiency and safety. Choose Enjue, choose a proven and reliable commitment.
