### Type 10

###### FRONT COUPLERS

##### Type 10

##### Automatic coupler type 10

The automatic coupler head type 10 is designed for regional and intercity, high-speed trains and railcars. It is compliant with the Technical Specifications for Interoperability (TSI) for the European rail system. This automatic coupler system is part of Dellner’s modular design concept, which is characterised by excellent spare parts availability and very low maintenance costs.

The automatic coupler type 10 is supplied with a pivot anchor as a deformation unit for crash absorption. The train coupler can be fully integrated with Dellner’s Crash Energy Management system. It comes as a top mounted electrical coupler including D-REX ethernet connection and pneumatic connections for main air and break air systems.

### Type 12

###### FRONT COUPLERS

##### Type 12

##### Automatic coupler type 12

The type 12 automatic coupler head is designed for regional, intercity, and high-speed trains as well as metros. The coupler head type 12 is part of Dellner\`s modular design concept. It comes with a pivot anchor with an integrated release function, allowing the coupler to shear off in the event of a collision.

Product details

Centre section with gas hydraulic damper
Pivot anchor with internal release function
Side guide horn for increased gathering range
Bottom mounted electrical coupler including D-REX (100 Mbit Ethernet connection)
Pneumatic connections for main air and uncoupling air
Buff/Draft strength: 1500/850 kN

### Tight lock type H coupler

###### FRONT COUPLERS

##### Tight lock type H coupler

##### Tight lock type H coupler

The tight-lock Type H coupler, like the Knuckle coupler, is based on the design of the Janney coupler. This type of coupler is particularly common in the USA.

The Dellner tight-lock Type H coupler is available for regional, intercity and high-speed trains, as well as railcars. It complies with the American Public Transportation Association (APTA) PR-CS-RP-019-12 Rail Transit Standard. The coupler features an anti-rotation joint, and its design ensures that, in the event of a collision, the end frames are brought together in a way that minimizes vertical and lateral movement between the coupled vehicles and the impacting vehicles.

The tight-lock Type H coupler is rigorously tested under both static and dynamic conditions and is equipped with a mechanical Knuckle coupler head. The coupler features a rubber draft gear for regenerative energy absorption, while non-regenerative energy absorption is controlled by a deformation tube. The force and stroke characteristics of the deformation tube can be adjusted to meet the vehicle manufacturer's crash energy management requirements.

Product details
