Longwall Mining Chains Surface Finish/Coating Review
For longwall mining chains operating underground, corrosion is a persistent threat that works in concert with fatigue and abrasion to shorten service life. Surface finishes are the primary defense against this, but each option represents a compromise between corrosion pr...Read more -
EN818-7 Fine Tolerance Hoist Chains: Engineering Demands and Manufacturing Challenges for Types T, DAT, and DT
EN818-7 is the European standard that specifies safety requirements for fine tolerance hoist chains, Grade T, intended for use in serial chain hoists—both manual and power driven. Unlike general-purpose lifting chains covered under EN818-2 (which are medium-tolerance cha...Read more -
Steel Materials Consideration for Longwall Mining Chains
Longwall mining chains are among the most critical yet cost-intensive consumable components in underground coal extraction. As a result, many overseas clients — particularly for smaller chain sizes such as 14×50 mm, 18×64 mm, 19×64 mm, and 22×86 mm — are actively explori...Read more -
Introduction to Round Link Chain Connectors for Cement Plant Bucket Elevators
In the demanding environment of cement plants, bucket elevators rely not only on robust round link chains but also on the critical connectors that serve as the indispensable interface between the chain and the buckets. These connectors, typically conforming to DIN 745 an...Read more -
Mastering the Depths: The Critical Role of Quality in Pump Lifting Chains for Water Treatment
In the demanding world of water treatment, the pumps that handle seawater and brackish water are the unsung heroes of the operation. These are not ordinary pumps; they are high-cost, critical assets engineered to resist the corrosive nature of saline environments while m...Read more -
The Critical Role of Round Link Chains in Power Plant Ash Conveyor Systems
In the demanding environment of a thermal power plant, the consistent removal of ash is a non-negotiable operation. The efficiency of the entire facility hinges on the reliable performance of the ash handling system, and at the very heart of this system lies the submerge...Read more -
The Non-Negotiable Standard: Quality Assurance in G80 and G100 Lifting Chains
In the world of overhead lifting, there is no room for error. A suspended load is not just material; it is a potential hazard. This is why the quality of a lifting chain—whether Grade 80 (G80) or the higher-tensile Grade 100 (G100)—can never be overstated. For engineers ...Read more -
Conquer Downtime: Solving Chain Knuckling and Mastering Longwall Conveyor Maintenance
For longwall operations, unexpected conveyor downtime is the enemy of productivity. While failures can seem sudden, they often stem from preventable mechanical issues. Two of the most critical areas for focus are the persistent problem of chain "knuckling" and the founda...Read more -
Durability Analysis of Round Link vs. Alternative Chain Designs for Longwall Conveyors
A Technical Perspective 1. The Durability Imperative Reliability is paramount in longwall mining, where AFC-related failures are a leading cause of unplanned downtime, accounting for approximately 27% of total production stoppages. The ...Read more -
Further Review On Round Link Chain Heat-Treatment, Breaking Force and Elongation
The balance between strength and ductility in high-grade lifting chains like G80 and G100 is fundamentally governed by their heat treatment. Achieving a higher tensile strength (moving from G80 to G100) inherently involves metallurgical trade-offs that directly impact el...Read more -
To Learn More About Round Link Chains Breaking Force Testing
Breaking force testing is a fundamental and mandatory quality control procedure for round link chains used across industrial and lifting applications. This paper outlines the methodology, significance, and key considerations for performing accurate breaking force tests, ...Read more -
