Railcar Knuckle: Made of AAR M-201 Grade E steel

Type and description

A rail car coupler knuckle that meets AAR (Association of American Railroads) standards is a device that connects and maintains stability between cars.

First of all, the coupler knuckle is made of high-quality steel material and has undergone strict quality control and testing. It has high strength and wear resistance, and can withstand the impact and tension between trains. In addition, it maintains its performance and reliability in harsh climatic conditions.

Secondly, the coupler knuckle design conforms to the geometric parameters of the AAR standard, ensuring an exact match with other vehicles’ shackles or couplers. It usually has a ring interface for the coupler and eye and is secured with bolts or pins. This structure can provide a stable connection and ensure the accuracy of force transmission. In addition, the coupler knuckle is equipped with reliable safety devices such as locking devices or safety pins. These safety devices can ensure that there will be no loosening or separation during the connection process between vehicles, thereby improving the stability and safety of the connection.

Finally, AAR-compliant coupler knuckles undergo rigorous testing and inspection to ensure they meet durability, reliability and safety requirements. These tests usually include static load test, dynamic load test and fatigue test etc. to verify its performance and quality.

To sum up, AAR-compliant railroad car coupler knuckles have high-strength materials, accurate geometric parameters, reliable connections, and safety devices. It can stably connect and maintain the connection between vehicles, ensuring the safety and stability of train operation.
