AAR standard grade E steel coupler common characteristics:

Coupler high structure strength, safety performance is reliable, free exchange,The latest production of coupler,All structure with prevent fall off.SBE type coupler is to prevent the coupler fall off,SE type coupler is to prevent the coupler up or down fall off.

AAR truck standard coupler is the mainstream of the heavy-load transportation products.

It in improving transportation safety reliability and efficiency of the train has obvious advantages.


1.E type coupler including small gaps coupler, even hung with longitudinal free clearance reduction, can reduce the train longitudinal impulse, improve vehicle dynamic performance.


2.F type coupler has the ability to interlock, automatic, Rotatable FR type coupler, reliable performance, reliable in three state function, curve through performance is good, locking pin to prevent jumped and bolt rod two methods to prevent function, AAR standard F type coupler is now main type F70DE.


3.EF type coupler curve through performance is good, enough structure to the horizontal momentum, the under of  motor vehicles is F type coupler is simple and EF type coupling head structure of E type coupler, a hook and hook tail using F type coupling structure.

The service life of our products have more advantages and wear-resisting performance, more diversified functions and USES, at the same time, we better production efficiency to save time cost for the customer.


Product quality guarantee

AAR standard grade E steel coupler adopts advanced quality testing equipment, a long time ago, the introduction of the portable 3 d laser scanner to enhance the quality of the product testing. The smelting and refining equipment of our product is the latest equipment, through chemical and mechanical properties after heat treatment products can reach the best level.

In the process of casting products of every link to chemical tests, in order to make the product achieve better mechanical performance at work.

Our products get the AAR certification
