As an added measure of safety, many countries are now requiring that passenger elevators have double redundant braking systems. Last fall, Japan made it mandatory that all new elevators have a double brake and double detection system. In order to meet the requirements in Japan, Europe and other countries, Ogura has developed the double RNB0.4WB-01 brake for home elevators.

The double brake is basically just that. It is two identical brakes mounted on one adaptor flange. Since the brakes are holding only, when the brakes are required to come on, both brakes operate at the same time, but in case of a problem with one of the brakes, the other one is designed to still have the capability to handle the torque load required. Both brakes are equipped with limit switches, to know when the brake is either engaged or disengaged. Besides the brake models shown Ogura also makes other series of hoist and elevator brakes.

Ogura has been producing clutches and brakes since 1938. Over that time, we have developed over 5,000 different models of clutches and brakes. Although Ogura primarily produces electromagnetic clutches and brakes, we also produce magnet particle, mechanical, pneumatic, hydraulic and a variety of specialty products. Ogura is the world's largest manufacturer of electromagnetic clutches and brakes. Current manufacturing capacity is over 30 million units per year. To provide localized support, we have fourteen manufacturing plants spread throughout the world in Asia, The Americas, and Europe. All manufacturing facilities are ISO recognized and conform to the ISO 9001;2008, ISO 140001, and ISO/TS 16949.
