Janney coupler
(1) Coupler Head
Material: Forged high-strength steel (e.g., 25CrMo4).
Locking Mechanism:
Automatic locking jaws (spring-loaded).
Pneumatic/electric release (optional).
Wear Pads: Replaceable friction surfaces.
(2) Draft Gear (Buffers & Shock Absorber)
Type: Hydraulic or elastomer-based (e.g., Fleischmann-type draft gear).
Energy Absorption: ~30–40 kJ per stroke.
Stroke Length: ~80–100 mm.
(3) Coupler Shank
Material: High-strength steel (e.g., S355J2G3).
Length: Adjustable (typically 1,000–1,200 mm).
(4) Mounting & Pivot System
Attachment: Bolted to wagon underframe (UIC 571 compliant).
Pivot Mechanism: Allows vertical/lateral movement (±15°).
