I. Risks of Using Inferior Track Chains
Consequences of Low-Quality Chains:
- Increased Unexpected Downtime: Low-quality track chains are more prone to breakage and wear, leading to frequent and unexpected machine stoppages. This downtime can disrupt project timelines, increase labor costs, and result in significant financial losses due to idle machinery.
- Safety Risk for Operators of the Construction Project: Inferior track chains can compromise the stability and control of asphalt milling machines. This instability poses a safety hazard to operators and other personnel on-site, increasing the risk of accidents and injuries. Ensuring the use of high-quality chains is critical for maintaining a safe working environment.
- Higher Replacement Requirements and Direct Expenses: Poor-quality track chains wear out faster and require more frequent replacements. This not only incurs direct costs for purchasing new chains but also increases maintenance expenses. The cumulative effect of frequent replacements and repairs can significantly inflate operational costs, impacting the overall profitability of milling projects.
II. Basic Consideration Indicators to Compare Track Chain
Attributes Affecting Longevity:
- Resilience Capability: The ability to maintain its original shape, ensuring consistent performance of the chain over the long term.
- Abrasion Resistance: The capacity to withstand wear and tear, determining the longevity of a chain by maintaining usable dimensions.
- Alignment Precision on Each Link: The alignment level of each link in a track chain significantly affects friction levels, determining the smoothness of operation, reducing avoidable wear, and properly distributing operational force.
- Structure Design: Whether the area commonly wear while operating enhanced, this can greatly affect the longevity of a chain.
Attributes Affecting Failure Resistance:
- Structure Design: Optimizes force distribution and provides consistent lifespan, ensuring reliable performance and lifespan consistency. The design's ability to address pin hole break issues is crucial in determining the chain's resistance to premature failure.
- Tensile Strength: The maximum force the chain can resist during operation without deforming, enabling it to handle sudden improper forces.
Attributes Affecting Operation Performance:
- Load Capacity: Determines the maximum weight a track chain can support for a machine, maintaining consistent performance under various operating conditions and slopes.
III. Tips to Evaluate the Probable Performance of a Track Chain on Each Indicator
Tips to Assess Structure Design
1 . Solution for Pin Hole Breakage Issue:
Pin hole breakage is a common cause of track chain failure. Assess if the chain has specific structural optimizations to address this issue, as it is crucial for preventing unexpected failures.
2 . Thickness of the Common Wear Area:
Enhanced thickness in common wear areas can significantly prolong the longevity of a chain by reducing wear and tear.
Why These Solutions Are Hard to Deliver:
Enhancing the thickness of common wear areas can increase production costs due to higher material volume. Solutions for pin hole breakage issues require extensive testing, research, and advanced shaping equipment to deliver more complex structural designs.
Tips to Assess Abrasion Resistance, Resilience Capability, and Tensile Strength of a Track Chain
Stats to Review:
The tensile strength should withstand at least 650 kN with at most 200mm displacement.
1 . Forging vs. Casting:
Forging ensures better quality in the steel outcome of a track chain.
How It Affects the Attributes:
• Abrasion Resistance: Forging produces parts with a uniform and dense grain structure, enhancing wear resistance.
• Resilience Capability: Forged parts maintain their shape better under stress, improving resilience.
• Tensile Strength: Forging aligns the grain flow, providing greater strength and toughness.
2 . Advanced Heat Treatment Equipment:
Advanced heat treatment processes, such as induction hardening, increase precision and quality, and increase the thickness of wear resisted layer.
How It Affects the Attributes:
• Abrasion Resistance: Heat treatment increases surface hardness, creating a thicker wear-resistant layer.
• Resilience Capability: Enhances the internal structure, improving the ability to recover shape after deformation.
• Tensile Strength: Alters microstructure, making the material stronger and more capable of resisting high forces.
3 . Materials Selection:
Selecting high-quality, wear-resistant materials is crucial.
How It Affects the Attributes:
• Abrasion Resistance: High-strength alloys resist surface wear better and increase the possible thickness of wear resisted surface.
• Resilience Capability: Resilient materials withstand deformation and return to shape.
•Tensile Strength: High-strength alloys provide superior tensile strength, making the chain more durable.
Why These Solutions Are Not Widely Adopted:
Methods like forging are more expensive than casting. Advanced equipment and high-quality materials increase costs, making manufacturers reluctant to adopt these solutions.
Tips to Assess Link Alignment Precision on Each Link
1. Advanced CNC Multi-Axis Auto Lathe:
These lathes ensure precise alignment of each chain link.
How It Affects the Attributes:
• CNC lathes achieve tight tolerances, automate shaping, and allow real-time quality control, ensuring each link is identical and reducing misalignment. Traditional methods have looser tolerances and manual processes, leading to variability and errors.
Why Advanced CNC Multi-Axis Auto Lathes Are Not Widely Adopted:
These machines require significant investment in high-precision equipment and skilled operators, making them more expensive to purchase and maintain.
Tips to Assess Weight Load Strength
Stats to Review:
The chain load strength should be at least 1.7 times the machine's weight. A load capacity of 2 times indicates top performance.
Why This Is Not Widely Delivered:
Achieving high load strength involves combining solutions for abrasion resistance, resilience capability, and tensile strength, which increases costs. Most manufacturers are unwilling to incur these expenses.
