The AAR (Association of American Railroads) followers

Type and description

The AAR (Association of American Railroads) compliant railroad car coupler follower is a critical device for connecting railcars and ensuring the transmission of tractive forces. The follower is a brief introduction to this coupler follower: AAR-compliant coupler plates are generally made of high-strength steel to ensure excellent load-carrying capacity and durability. This steel is specially treated to increase its strength and corrosion resistance, ensuring reliable operation in the various conditions of rail transport. The coupler follower is designed to meet the strict requirements of the AAR standard regarding geometric parameters to ensure a good fit with other couplers or vehicles. It has a standard circular interface for a secure connection with a coupler or other attachment device. To enhance the stability and security of the connection, AAR-compliant coupler followers are often supplied with locking devices or safety pins. These devices ensure that the connection between the coupler and the follower plate is strong and will not loosen during operation. In addition to meeting the design requirements of the AAR standard, the coupler follower must pass a series of tests and inspections to ensure it meets quality and performance standards. These tests usually include static load tests, dynamic load tests and fatigue tests to verify its reliability under significant loads and operating conditions.

In conclusion, AAR-compliant railway car coupler followers are manufactured from high-strength steel with accurate geometric parameters, reliable connections and safety devices. It ensures a stable connection between railway vehicles and contributes to the safety and reliability of railway transportation.
