Train Car Coupler Interlocking Rotary Coupler No.16 Coupler for Side Dump Railcar

Breif introduction:

No.16 coupler is specially designed for ‘Daqin’ coal transportation hopper wagons. It could allow dump unloading without dismounting the coupler. It adopt AAR S117-67 ‘F type interlock coupler profile’.

Main technical features of No.16 coupler:
1. No.16 coupler could be coupled with 13B coupler, 17 coupler, AAR E coupler, AAR E/F coupler, and AAR F coupler.
2. No.16 coupler is made of Grade E high strength low alloy steel. The minimum static tensile failure loads of coupler body and coupler knuckle are 4005kN and 3430kN.
3. The free clearance of closed couplers’ profiles is 9.5mm, less longitudinal impact during train running, better longitudinal dynamic performance.
4. No.16 couplers comply with TB/T 456 standard ‘Automatic coupler buffer device for vehicle with coupler’.
5. The coupler head is equipped with an interlocking device, which could realize automatic centering interlocking after coupled. This centering could reduce the abrasion of coupler body and coupler knuckle, improve the stress state of coupler body and coupler knuckle, and prolong the service lifespan. It could also prevent the coupler separating from vertical direction after coupled, help to transfer the torsional moment of the tipper, and improve the rotation performance of coupler;
6. The end surface of No.16 coupler is approximately circular, reducing the rotation resistance between coupler body and coupler support seat; the contact surface of coupler yoke and slave plate is spherical, which can rotate 360° around the longitudinal center line of the car body relative to coupler yoke, so that the wagon could be unloaded without disassembling the couplers (only need to turn the dumper), thus improving the unloading efficiency significantly.
