Automatic Couplers

​AAR couplers are the standard for railcars in the American market. The Dellner AAR couplers are designed as per AAR standards regarding ma terials, compatibility and strength requirements. They transmit large buff and draft loads and couple automatically. AAR couplers can be combined with state-of-the-art, high-energy absorption draft gears.​​
