Engineering Introduction: Mastering the Extended 300mm Span
Systemic longevity in high-capacity overhead transport is dictated by the rigidity of the chain's connecting links. Hangzhou Ocean Industry Co., Ltd. introduces the QXG300 Flange Plate, a specialized heavy-duty component designed for the 300mm pitch series. As facilities scale up for larger workpieces-such as bus frames or heavy industrial equipment-the painting line chain QXG300 conveyor chain becomes the necessary infrastructure. However, an extended pitch places significantly higher localized stress on the connecting link than smaller models.
Our QXG300 flange plates are engineered to serve as the high-tensile "bridge" for these large-span systems. By utilizing a thickened alloy steel profile, we ensure that the industrial conveyor system chain maintains its structural geometry even under maximum take-up tension. This component is the primary interface for the fixed hanging plate chain, meaning it must simultaneously manage horizontal drive forces and vertical gravitational loads. Whether integrated into a single guide conveyor chain or a custom heavy-rail layout, the QXG300 flange plate from Hangzhou Ocean Industry provides the mechanical security required to eliminate the "chain-stretching" phenomenon common in oversized heavy duty conveyor chain operations.
Core Technical Features & Specifications
Extended Pitch Structural Integrity: Specifically reinforced to handle the increased lever arm torque associated with a 300mm link span.
Bore-Hole Precision: CNC-drilled pin apertures ensure a zero-tolerance fit, preventing mechanical "surging" within the industrial conveyor system chain.
Vacuum Heat Treatment: Every plate undergoes controlled quenching to achieve a surface hardness of HRC 40-45, providing superior wear resistance at the joint interface.
Optimized Stress Distribution: The flared geometry of the QXG300 flange plate helps dissipate tension away from the pin holes, preventing cracks in heavy duty conveyor chain setups.
Multi-Stage Chemical Coating: Finished with a specialized electrophoresis barrier to withstand the high-humidity and corrosive degreasing zones of a painting line.

Engineering Selection & Implementation Strategy
Engineering Selection Advice (The 300mm vs. 250mm Choice)
The decision to utilize QXG300 over the 250 series is typically driven by the "Component Footprint." For workpieces exceeding 2 meters in length, the 300mm pitch reduces the total number of moving joints by 20%, which significantly lowers the maintenance requirements of the industrial conveyor system chain. However, because the distance between the single guide conveyor chain rollers is wider, the QXG300 flange plate must be checked for lateral deflection. Hangzhou Ocean Industry recommends this reinforced plate for any system where the single-point load exceeds 60kg.
Applicable Environmental Conditions
Thermal Dynamics: Stabilized for continuous operation in 220°C - 260°C curing ovens.
Chemical Exposure: Resistant to alkaline phosphate pre-treatment and acidic electro-coating vapors found in a painting line.
Speed Management: Best suited for stable, constant-velocity heavy duty conveyor chain operations between 0.5 and 8 m/min.
Industrial Application Scenarios
Public Transit & Bus Production: Connecting the painting line chain QXG300 conveyor chain loops for large body panels and chassis.
Agricultural & Earthmoving Equipment: Maintaining the link integrity for heavy duty conveyor chain systems used in tractor and excavator finishing.
Industrial Infrastructure: Supporting large-scale heat exchangers and electrical transformers in an industrial conveyor system chain environment.
Installation & Working Principle
Operational Principle
The QXG300 Flange Plate functions as the load-bearing side-wall of the conveyor link. It acts as the anchor point for the chain pins, which in turn hold the rollers in place. In a single guide conveyor chain, these plates provide the rigid structure that keeps the chain centered within the track. By mounting the fixed hanging plate chain directly to these reinforced flange plates, the vertical weight of the load is distributed across the entire 300mm pitch, preventing localized deformation of the track rail.
Common Installation Best Practices
Pitch Verification: During assembly, ensure that all QXG300 flange plates are from the same production batch to maintain absolute pitch consistency across the industrial conveyor system chain.
Pin Lock Security: Always use high-grade cotter pins or snap-rings to ensure the flange plate remains seated against the link rollers under high-speed operation.
Alignment Audit: Post-installation, run the heavy duty conveyor chain for 24 hours and inspect for "side-rubbing" on the plate faces, which indicates a track curve misalignment.
