Overview
The 856A3387G03 is a high-performance, heavy-duty Engine Transport Stand Locking Pin and modular positioning hardware custom-engineered for the rigorous logistics, hangar relocation, and overhaul (MRO) handling of commercial turbofan engines. Classified as a flight-critical powerplant handling asset and specialized Ground Support Equipment (GSE), this locking pin is purpose-built to provide a rigid, deflection-free interface between the engine’s primary structural lugs and the transport dolly assembly. Manufactured by JUNXUN to comply with strict aerospace dimensional and material integrity standards, the 856A3387G03 ensures that the engine remains locked in an absolute, vibration-isolated position, effectively preventing structural load-shifting, case damage, or accidental detachment during intensive hangar-based transit or maintenance sequences.

Key Points
High-Shear Structural Metallurgy: Fabricated from premium, heat-treated high-tensile alloy steel certified to withstand the immense static and dynamic loads exerted by fully assembled propulsion units during transit.

Precision-Fit Alignment Geometry: Engineered with micro-tolerance shaft diameters and chamfered insertion tips that ensure seamless, jam-free mating with standard engine transport stand receiving sockets.

Vibration-Resistant Secure Locking: Features an integrated locking-detent or bolt-collar interface that anchors the engine firmly to the stand, preventing operational vibration from inducing hardware loosening.

Corrosion-Resistant Surface Treatment: Outfitted with advanced aerospace-grade passivation and anti-corrosion coatings, ensuring durability in extreme hangar environments and resistance to aviation fluid degradation.

Applications
Commercial Engine Fleet Transit: Deployed by global airline engineering divisions for the secure movement of heavy-weight turbofan modules between hangar bays and flight-line staging areas.

MRO Depot-Level Positioning: Utilized within heavy engine repair cells to dock and stabilize the propulsion unit during complex module teardowns, cleaning, and build-up operations.

Airlines Ground Support Equipment Logistics: Essential specialized GSE hardware for commercial carrier tool cribs and third-party maintenance organizations to ensure reliable, zero-defect engine handling and airworthiness compliance.

856A3387G03 is a precision-engineered specialized component for critical aviation ground support equipment (GSE) and professional aircraft maintenance rig systems, compatible with global mainstream commercial narrow-body, wide-body and regional aircraft fleets. Manufactured in strict compliance with AS9100D aerospace quality standards and FAA/EASA safety protocols, it is precision-machined from high-strength corrosion-resistant aerospace-grade alloy with a rugged wear-proof and anti-corrosion surface finish, optimized to endure harsh airfield operational conditions including continuous vibration, mechanical impact, extreme temperature fluctuations and chemical exposure from aviation fluids like fuel and hydraulic oil. It features ultra-tight application-specific dimensional tolerances and industry-standard mounting interfaces for seamless integration into GSE and maintenance assemblies, delivering superior structural stability and long-term wear resistance to effectively boost the operational reliability and service life of ground support equipment for worldwide aircraft MRO and on-tarmac ground support operations.
