Enhancing Safety Technologies in Line with the Increasing Speeds of Rail Transportation
As a world-class high-speed railway system, the Shinkansen represents Japanese expertise at its best. Because the speed of these trains can exceed 300 km/h, the technology used to control them needs to ensure absolute safety and reliability.
As part of our commitment to making technological contributions to the safety of high-speed rail transportation, Nabtesco has been developing Shinkansen brake systems and door operating units, both of which are core components of the trains. Our high-standard technologies are also widely used in other transportation systems both inside and outside Japan, including local trains and new transportation systems.
Furthermore, in line with the increasing speeds, railway operators have recently been increasingly intent on reducing the size and weight of machinery and equipment as larger cabin space and environmental measures become more important. To help their trains run faster and more smoothly, Nabtesco is currently developing technologies to boost the evolution of rail transportation in the future.
In Japan, we have around 50% of the market share (Nabtesco’s estimates) for brake systems and a roughly 60% share (Nabtesco’s estimates) for door operating units. Of particular note, Nabtesco’s door operators are installed on all carriages of the Series N700 Shinkansen.
Social Value Provided by the Business
- By providing highly safe and reliable products, we contribute to railroad transportation systems running safely and on time.
- Optimizing railroad transportation helps to reduce traffic congestion as well as CO2 emissions from automobiles.
Main Products
Unit Brakes
The unit brake incorporates the integral functions of a conventional foundation brake rigging and a built-in automatic slack adjusting mechanism. Compared to existing foundation brake units, the product offers reduced size and weight, simplified maintenance, greater noise protection, and heightened consistency of braking efficiency.
Brake Operating Units for Railroad Vehicles
This system is configured as a unit, comprising a brake operating device that plays the core role in the electric commanding air brake system and the air brake valves that provide the brake cylinder pressure output for service and emergency braking.
Door Operators for Railroad Vehicles
Offering a tremendous variety of door operating units, our product line-up comprises door operators that meet the needs of a wide array of applications, from high-speed trains like the Shinkansen to commuter trains and ultra-low-floor light rail vehicles (LRVs).
