Draft gear system for railway

Product Advantages and Features:

Our company can have the strong capacity of supplying coupler , draft gear and yoke whole set, including some specifica type buffer gear

Small Curve Radius Coupler, difunctional coupler, which includes one

AAR coupler head inaccord with the Number 10-Acontour at coupler mating lines and

one UIC standard Screw coupling.Thesetwo coupler heads are interchangeable.When

Folding Central Coupler coupled toAAR standard railway system,AAR coupler head will

workand if itcoupled to UIC standard railway system, screw couplingwill work.AAR/ UIC

Folding Central Couplerassemblestogether with AAR standard draft gear and coupler yoke.

It hasbeenwidelyused in the countries and regions where mixedstandards are being.

applied,like Southeast Asia.

AAR coupler head strength : ≥3000KN

Screw coupling strength: ≥1350KN

AAR standard coupler is the leading product for heavy duty railway wagons in the worldwide. Our AAR couplers are furnished with bodies, knuckles, and locks of quenched and tempered grade E steel, which are high strength structure, reliable safety performance, and high interchangeability. It obtains obvious superiorityin improving the safety and reliabilityof transportation and the efficiencyof train formation. AAR standard coupler mainly includes type E, type F, type FR and type EF. Except type F coupler and type FR coupler are equipped with primary anti-creep mechanism to prevent disengagement, the new-built type E and type EF couplers have the anti-creep mechanism design too.

1)E type coupler: The latest model is E60EE and approved to be AAR standard coupler in 2000. Comparing with the previous model E60DE, it optimizes wall of knuckle side, knuckle tail end face and lock face, and coupler lock face structure, further controls the longitudinalfree clearance of coupler. Besides, AAR present service E type coupler has E60DE, SBE60EE and SBE60DE with bottom shelf, SE60EE with top and bottom shelf, and SBE67DE with bottom shelf and long body.

2)F type and FR type coupler:F type interlock coupler obtains high strength structure, small coupling clearance, anti-creep, interlock and automatic centering functions, reliable three states operation and anti-creep performance, good curve passing performance. FR type coupler is a rotatable interlock coupler, it was developed to meet the requirement of mass goods transportation and turnover discharge. AAR present service F type coupler has F70DE, SF70DE with top shelf, F79DE with long body, etc. FR type coupler has FR207AE, FR209E, etc.

3)EF type coupler: It was developed on the base of E and F type couplers to provide enough lateral oscillatingquantity for train curve passing. It mainly applies to the railway wagons with longer traction beam. It obtains the features of high strength structure, good curve passing performance. AAR present service EF type coupler has E68DE, E69CE, SBE68DE with bottom shelf, SE68DE with top and bottom shelf, etc.
