nir-vana innovation network

The company was founded in 2019 in Kayseri. The company develops and manufactures subsystems used on rolling stock and maintenance machines. It has completely specialized in the railway vehicles sector. It has developed many high-value-added products as a result of R&D studies since it was founded and commercialized all the products it developed. The company has established commercial and engineering cooperation with companies from the United Kingdom, the Netherlands, and South Africa. They make representativeness in Turkey on behalf of their partner companies. Their partner companies also make representativeness in their regions in equivalence. THEIR PRODUCT GROUPS 1. RAILWAY VEHICLES SUBSYSTEMS 1.1. AXLE BOX The axle box is the fitting between the rotating wheelset and the semi-static bogie chassis. All forces acting between these components are transferred through springs, dampers, and guide elements. Axle boxes have a significant impact on operational safety, reliability and rail system vehicle costs. 1.2. SANDING SYSTEM The sanding system is used to increase the friction force between two surfaces thanks to the sands with a special composition and particle size blasted between the wheel and the rail. The stopping distance is used to prevent skidding and aquaplaning. 1.3. WHEEL FLANGE LUBRICATION SYSTEM To achieve the best balance between wear, lateral forces in the curves, and fuel efficiency, it is necessary to control the frictional forces on the rail surfaces where the wheels come into contact. Optimum driving values are achieved by lubricating the wheel flange with the right time, amount, and method with onboard lubrication systems. 1.4. DRIVER FOOTREST Driver footrest provides an ergonomic seat opportunity for drivers and reduces the tiredness coefficient to a minimum level. By providing the driver with a stable position, the distance between the driver and critical control devices is reduced. In this way, the response times are minimized, which is important in emergencies. Its adjustable structure allows it to create the most suitable cruising position for each driver. 1.5. BO'54 RESILIENT WHEEL Resilient wheels are used effectively to increase navigational comfort and reduce maintenance costs for railway vehicles. The resilient wheels consist of the steel wheel center, steel tire, and rubbers that absorb shock and vibration. 2. RAILWAY VEHICLES MAINTENANCE MACHINES 2.1. MOBILE SAND REFILLING VEHICLE Mobile Sand Refilling Vehicles are used to fill sand tanks in railway vehicle sanding systems. When the vehicle comes to the maintenance workshop, the sand level is checked and sand reinforcement is made. 2.2. MOTORIZED SAND REFILLING VEHICLE Motorized sand-filling vehicles are produced in integration with self-propelled and electrically powered pickup trucks of different sizes. It is produced in versions with a carrying capacity of 0.75t, 1ton, 2ton… and more upon request. 2.3. ELECTRIC RAILCAR MOVERS It is used to move railway vehicles for short distances without needing to run the vehicles. Since battery-powered maneuvering vehicles have much more efficient and flexible mobility compared to railway vehicles, they provide dramatic improvements in fuel efficiency, maintenance times, occupational safety, and operational capabilities. 2.4. RESILIENT WHEEL PRESS The company's wheel presses allow you to make a flawless assembly by applying the pre-tensioning force required for mounting the Bo'54 wheel at a precise position, force, and speed. Machines can be customized according to customer demands and different types of wheels. 2.5. BOJI PRESS The bogie press is a vital test and maintenance machine that allows bogies to be balanced after manufacturing or maintenance before mounting under the vehicle. They are currently working with several countries and looking for commercial and distribution agreements to expand their network.
