The Type 330 is used primarily in light rail and tram applications. It is small yet strong. Locating the electrical coupling underneath at the head is also possible. The coupler can transmit a buff load of 800 kN and a draft load of up to 600 kN.
Its especially compact and lightweight construction makes the Type 430/530 Scharfenberg coupler the ideal type of coupler for low-floor trams and monorails. As a folding coupler, it also fits behind front covers. It can transmit compressive and tensile forces of up to 300 kN. The type 530 was mainly developed for the Eastern German market and is compatible to the TGL couplers that used to be very common there.
Modular transitional coupler
Transitional couplers are used when vehicles have different types of couplers or coupling heights, e.g. when shunting and towing. Until now, this frequently required special designs. The new, modular transitional coupler separates the different components into two separate heads and an adapter that forms the step. The two separate heads can also be connected to one another directly. This makes it possible to combine coupler heads of any kind and at different heights easily into an transitional coupler.
CFP transitional coupler
When towing is necessary or when shunting, transitional couplers are often mounted on the train for a short period of time by the operating personnel. For this reason, they should be light yet still withstand the high operating loads encountered when towing entire trains. In order to reduce weight even further, coupler bodies can be constructed from CFRP (carbon fiber-reinforced polymer) today. Until now, this high-performance material has been used primarily in aviation. Load tests have provided results that demonstrate its performance capabilities. These can be optimized even further through refinement.
Albert couplers are used primarily on vehicles that are coupled only infrequently. The connection is made by means of pins. The coupler's drawbar can be provided with a folding knuckle (joint) which allows the uncoupled drawbar to be folded under the car.
