레일 & 광산용 자동차 커플러: 군용 등급 내구성, 다국적 표준, 고하중 성능 (여객/화물/광업)

Overview of Rail Car Coupler

This series of rail car couplers are core connection devices designed for railway transportation and heavy-load mining scenarios, focusing on mechanical structure stability, basic functional compatibility and full-condition durability. The products cover three major areas: 여객 열차 (EMU/urban rail), freight heavy-load, and mining locomotives. They support manual/semi-automatic coupling, are compatible with multi-national railway standards and special mining needs, and ensure train/mine car marshaling, traction transmission, longitudinal impact buffering and basic gas-electric docking functions. They are suitable for high-frequency, high-load transportation tasks in harsh environments.

Features of Train Coupler

Military-grade materials and structures

• Coupler body material（metal hooks）: high-strength low-alloy steel (such as Q345E, ASTM A572 Gr50), tensile strength ≥600MPa, yield strength ≥345MPa, impact resistance increased by 40%.
• Mining reinforced version: the surface of the hook tail frame and hook tongue is thickened with chrome plating (≥80μm), the wear resistance is increased by 3 타임스, and it is suitable for the dust and gravel impact environment of open-pit mines.

Multi-scenario compatible design

• Railway standard: compatible with mainstream railway coupler interfaces in many countries, supporting transnational intermodal transshipment.
• Mining customization: optional wide-body hook for mining (coupler tongue opening angle ≥ 110°), adapted to wide track gauge (1435-2000mm) and overload requirements (single hook load ≥ 350 톤).

Simple operation and safety redundancy

• Couplering mechanism: three-level locking structure (main coupler tongue + anti-unhooking coupler tongue + mechanical locking pin), manual couplering torque ≤ 60N·m, hooking success rate ≥ 99.5%.
• Anti-unhooking guarantee: The hook tongue pin hole is built with a double-row needle bearing to reduce hooking wear; the coupler tail frame is equipped with an anti-unhooking baffle to prevent longitudinal impact unhooking.

Technical Specifications of Train Coupler

Core functions of Train Coupler

Mechanical coupling and locking

• Railway type: After the convex cone of the coupler tongue is engaged with the concave cone hole, the lock pin is manually inserted and rotated 90° to lock, and the coupling time is ≤15 seconds/section. Train connect and coupler railway.
• Mining type: The opening angle of the couplertongue is expanded to 110°, supporting blind coupling of mine cars at a slope of ±20°, and the width of the hook body is increased by 30% to resist lateral impact.

Buffering and vibration reduction system

• Railway standard version: rubber buffer + friction buffer combination, energy absorption rate ≥75%, impact attenuation time ≤0.8 seconds.

• Mining enhanced version: hydraulic buffer (optional) + rubber spring composite structure, adapted to high-frequency impact in open-pit mines (impact ≥200 times per shift)

Adaptability to extreme environments

• Railway type: coupler surface is galvanized + 다크로메트코팅, salt spray test ≥ 720 시간, anti-corrosion ability is improved by 50%.
• Mining type: The coupler body is fully sprayed with wear-resistant ceramic coating (hardness ≥ 9H), and the anti-gravel impact performance is improved by 200%; optional heating module, no jamming when connected at low temperature of -40℃.

Application scenarios of Train Coupler

Railway transportation
Intercity EMUs, heavy-load freight, and cross-border transport.
Mining transportation
Open-pit mines: Adapt to 220-ton mining dump trucks, and the impact resistance of the coupler body matches the violent bumpy working conditions of ore transportation after blasting.
Underground tunnels: Optional mining narrow-gauge couplers (gauge 900mm), with adjustable coupler height (400-600mm) to adapt to low tunnel operations.
Mixed deployment of multiple models: supports mixed deployment of mining electric locomotives, hydraulic support transport vehicles, and personnel transport vehicles, with a single-row load capacity of ≥5,000 tons.
