This bogie is designed for operation on the 1435 mm standard gauge.

It is suitable for new-built wagons and wagon maintenance and refurbishment.

• The axle load is 22.5 t, and the operating speed is 120 km/h.
• The bogie mainly comprises wheelsets, axle boxes, suspension devices, bogie frame, foundation brake rigging, and load-proportional valves.
• The bogie frame is of welded construction, featuring high structural rigidity and low unsprung mass.
• Equipped with a spherical pivot bearing, the contact area between the bogie pivot and the car body is increased,resulting in uniform load distribution and enhanced capacity to transmit longitudinal and transverse forces.
• A two-stage stiffness spring suspension system is adopted to improve the vertical ride comfort of empty wagons, ensuring excellent dynamic performance for both empty and loaded conditions.
• The application of Lenoir damping devices satisfactorily meets the demand for different damping forces between empty and loaded wagon operations.
