Engineered for heavy-duty industrial and mining applications, our AAR Type 10/A Automatic Coupler offers a robust, reliable, and safe connection solution for narrow-gauge rolling stock. Designed with high-precision cast steel, it ensures maximum durability under high-impact conditions.

Key Features:

• Automatic Locking: Increases operational efficiency and personnel safety.

• Heavy-Duty Casting: Manufactured from premium cast steel for superior tensile strength and wear resistance.

• Versatile Mounting: Equipped with a standard 4-bolt mounting flange for easy installation on various chassis types.

• Wide-Angle Swing: Designed to handle sharp curves and uneven track conditions common in mining and tunneling operations.

Applications: Underground Mining Wagons

• Steel Plant Slag Cars and Ladle Cars

• Tunneling Construction Trains

• Narrow Gauge Industrial Locomotives

Technical Specifications & Features

1. Product Classification

• Standard: Based on AAR (Association of American Railroads) design principles but scaled down for industrial use.

• Model: Commonly referred to as the 10/A Automatic Coupler (Small Pattern).

• Material: High-strength Grade C or Grade E Cast Steel (Quenched and Tempered).

2. Key Components & Mechanism

• Coupler Head: The "knuckle" design allows for automatic coupling upon impact.

• Knuckle : The pivoting part that locks the connection.

• Knuckle Pin : The vertical axis (visible in your first photo) that allows the knuckle to rotate.

• Locking Block : An internal gravity-fed or spring-loaded mechanism that prevents the knuckle from opening during transit.

• Shank & Yoke : The rear part of the coupler that handles the draft (pulling) and buff (pushing) forces.

3. Functional Advantages

• Automatic Coupling: Enables "hands-free" connection between wagons, significantly increasing safety in mining and factory environments.

• High Articulation: The rear mounting flange and pivot pin allow for horizontal and vertical angling, which is critical for navigating tight curves in underground mines or industrial plants.

• Standardized Compatibility: As an AAR-pattern device, it can usually couple with other AAR-style couplers of the same size, regardless of the manufacturer.
