Brakes with a System Rail Safety HANNING & KAHL

85 Years of Brake Competence Rail Safety HANNING & KAHL has been producing track brakes since 1928. The very serious discussion on the significance of road safety for passengers has always spurred us on the look for new technical solutions, to accelerate their development and to make sure that they are widely applied in practice. Following on from this commitment, the first electro-hydraulic spring-applied brake systems were produced in 1959. Today the product range in the Rolling Stock Division encompasses a wide selection of highly-sophisticated units for rail-based vehicles: spring-applied...

Spring-applied Actuator Full Force Spring-applied actuators are the “fail-safe ele-ments“ of the safety system in tram vehicles; if the energy supply fails, the braking force is provided with the force of a mechanical spring. The brake caliper design is particularly preferred in low-floor vehicles as there is not enough space for solutions which require brake riggings. Brake calipers are also lighter and they also have lower working strokes which reduces reaction time and the braking distance, too. Spring-applied brake calipers can either be mounted on the hollow shaft of the gear box, on single-running...

Apart from the spring-applied actuators, HANNING & KAHL also supplies so-called "Active" brakes, where braking force is generated by hydraulic pressure. This favourably-priced type of brake is an appropriate choice whenever the extra safety advantages of the spring-applied actuators are not essential. They are primarily deployed in the brakes in trailer bogies to support the electro-dynamic service brake and maximise brake force whenever emergency braking is called for. Active brakes fit well into the modular concept because they have the same mechanical interface as the spring-applied actuators....

HANNING & KAHL brake discs are designed with braking specifications and brake strengths in line with the requirements for urban transport vehicles. Brake discs are exposed to extremely high mechanical and thermic strain. Customised to the respective bogie/chassis designs and drive concepts, we offer a wide range of brake discs. Brake discs are primarily made from grey cast iron, nodular cast iron or cast from suitable steel alloys, and then machined.

Hydraulic power units supplied by HANNING & KAHL reliably control all functions necessary for operation of the braking unit. Our hydraulic power units have a compact design consisting of three parts: tank, manifold and hood. The particularly compact basic device can be fitted on request with convenient or special-purpose functions. These, however, require more installation space. Hydraulic power units are ideal for deployment in low-floor vehicles where very little space is available. It is possible to activate all the brakes on the bogie by means of a common hydraulic circuit or to control the...

Brake controllers form the interface between the HANNING & KAHL braking system and the vehicle controller. The hydraulic power units, and thus the braking force, are activated in line with the project-specific braking matrix. The brake controllers of type HEY und HEY-C deployed by HANNING & KAHL are found in light rail vehicles, trams and driverless metro vehicles. The controllers can implement certain functions with SIL2 in accordance with EN 50657 / EN 50128 (software) and EN 50129 (hardware), and also comply with standard rail-application norms EN 50155, EN 50121-3-2 and EN 61373. With its...

To extend connectivity, both control types can be equipped with different bus systems (CAN, MVB and Ethernet). Software download and extensive diagnosis are usually effected via Ethernet or CAN. The VSS valve control stage and the NSE control electronics are designed for less demanding tasks in braking management. They activate the brake in analogue/singlechannel manner per microprocessor. The PM (electronic semi-conductor contactor) component can switch on/off DC motors with a power up to 1KW wear-free. Brake controller HEY-C

IElektro-Hydraulic Modules HANNING & KAHL has added an electro-hydraulic module for hydraulic brake activation to its product portfolio designed especially for the use of hydraulic brake systems in metro vehicles. The ready-to-install, electro-hydraulic module comprises hydraulic pressure generation, pressure regulation and electric control in one. The wiring between the electronic brake control unit and the hydraulic system which usually takes place in the vehicle is already integrated. In basic version, the electro-hydraulic module is composed of proven standard components in modular design....
