Key Features / Benefits
. Corrosion Resistance
Available with coatings or made from upgraded alloy steel to resist corrosion in challenging environments.
. Fatigue Resistance
Engineered to withstand repetitive stress and avoid fatigue failures, ensuring long-term performance under cyclic loading conditions.
. Heat Treatment
Components are all heat-treated to improve hardness and wear resistance.
. Lubrication Options
Can include self-lubricating features or be compatible with advanced lubrication systems to reduce maintenance needs.
Key Benefits
Superior Strength and Durability:
Thickened Components: Thicker side plates, larger pins, and stronger rollers/bushings than standard chains withstand significant tensile and fatigue loads.
High-quality Materials and Heat Treatment: Made from high-strength alloy steels, they are often specially heat treated (e.g., induction hardening, shot peening) to maximize hardness, wear resistance, and toughness.
Shock Load Resistance: Designed to absorb large shocks and sudden load changes common in mining operations without premature failure.
Reliability in Harsh Environments:
Contamination Resistance: Operates effectively in environments with highly abrasive dust, dirt, moisture, and even corrosive media with tighter tolerances, superior sealing, or larger gaps (some types).
High Temperature Resistance: Able to maintain performance across a wide range of operating temperatures in mines.
High Power Transmission Capability:
Constant Ratio: Provides positive, slip-free drive, ensuring consistent ratios and high mechanical efficiency for power transmission, which is critical for synchronized motion and precise timing.
High Torque Capacity: Designed to transmit extremely high torque from the power source to the driven components, which is critical for heavy machinery.
Longer Wear Life:
Due to the use of high-quality materials and manufacturing precision, internal wear is reduced, resulting in longer service life and less frequent replacement.
Cost Effectiveness (Long Term): While the initial cost may be higher than a standard chain, its longer service life and reduced maintenance requirements generally reduce the total cost of ownership in demanding mining applications.
Applications
Excavators and Shovel Trucks: Drive systems for crawler propulsion, slewing mechanisms, and sometimes bucket articulation, where high torque and impact resistance are critical.
Drilling Rigs: Propulsion systems that transmit power to the drill bit, rotary table, or crawler drill.
Crushers and Mills: Drive components within these machines, such as rotating elements or feed mechanisms, require strong power and durability to handle large, tough materials.
Conveyor Drives (Main Drives): While chains also make up the conveyor itself (e.g., flight chains), heavy-duty drive chains are often used in the main drive units of large belt or plate conveyors, connecting the motor/gearbox to the head pulley.
Feeder Breakers: Transmit power to the breaking bars and conveyor components in these machines, which are used to screen and move coal or ore.
Shuttle Cars and Loaders (Mobile Equipment Drives): Provide drive to the wheels or tracks of these vehicles that move material within the mine.
Stacker Reclaimers: Used for bulk material handling in mines, they transmit power to large booms and reclaiming mechanisms.
Heavy-duty Pumps and Fans: In some cases, used to drive large industrial pumps or fans used for mine ventilation or dewatering.
