Railteco offer a complete assembly system for Coupler, Yoke, Draft Gear and other accessory. Per well-experienced working and professional design ability, we make a turn-key solution, design based on customer’s requirement and provide full sales and technical support from order to installment. We supply AAR 10A Type and H type coupler per customer’s drawing and specification. We can supply: AAR E Type AAR EF Type AAR F, FR Type, per AAR standard. SA-3 Coupler, per Russia standard. AAR E Coupler-EC-A The main parameters: Coupler connecting line to the coupler shoulder length: 298.5mm Maximum longitudinal movement gap: 11.5mm Maximum coupler horizontal range: >= 87.98mm Coupler's largest mobile space: 9.5mm Relative angle: the Maximum angle in the horizontal (when coupler knuckle hanging height 300mm) 6 °. Maximum allowable height difference between the two connected couplers’ Center are 150mm. Summary: Used for vehicle coupling can reduce the vehicle coupling gap, which reduces the vertical impulse, improving train longitudinal dynamic performance, extend service life of vehicles and their parts and components Yoke RTM-3 Draft Gear AAR E Type Coupler- EC-B Coupler connecting line to the coupler shoulder length: 298.5 (mm) Coupler Connecting line to the coupler end surface length 838.5 (mm) Coupler shoulder section dimensions 203x160 (mm) Maximum longitudinal coupling movement gap 11.5 (mm) Maximum relative angle (when two couplers are connected) horizontal 6 ° / vertical 2 ° 11 ' Maximum horizontal swinging angle 10 ° 40 ' Maximum allowable height difference between the two connected couplers’ Center are 75mm.
