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.
4. 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.
