By broadening its line of production by tightlock and AAR (american Association of Railways) couplers, Voith Turbo Scharfenberg has responded to existing market conditions and is capable of covering an additional coupler market segment.
The tightlock and AAR couplers which are mainly used in North America and Asia are characterized by its simple and robust design, high strength and low price. The can be used both on passenger trains and freight wagons.
Retractable electrical coupling for tightlock and AAR couplers
The contacts of the tightlock and AAR coupler electric heads are subjected to constant movement due to increased play (backlash) of the AAR coupler lock. This leads to reduced contact pressure and formation of arcing.
Benefits
The centring and locking features ensure a rigid and safe connection thus improving the contact pressure. |
