Breif introduction:
CA-3/SA-3 Coupler is the main coupler for former Soviet Union Railways. It has higher impact speed and has significant traction effect under the extreme climate conditions.
CA-3 type automatic coupler is the main coupler for former Soviet Union railways locomotive, coaches, freight wagons. It was defined as standard coupler. CA-3 coupler can tow goods with a total weight of more than 8000 tons under bad weather conditions.

CA-3 coupler has reasonable design and high structural strength. Its main parts are made of TB / T2942-E grade steel. CA-3 coupler is easy to connect and has good coupling performance. When two couplers are in free state, they can be connected once they are touched. The coupler has a unique ‘push’position, which is convenient for shunting operation. The free clearance between the connecting profiles of the two couplers is 10 mm, which belongs to the tight coupling type in structure. It has the characteristics of small coupling clearance, which can reduce the longitudinal impact of the train and improve the dynamic performance of the train.
At present, CA-3 automatic coupler is mainly used in the following countries: Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Lithuania, Latvia, Moldova, Russia, Tajikistan, Ukraine, Uzbekistan, Finland, Iraq, Turkey, Sweden, Norway, Australia, Slovakia, etc.
