Holding Brake produces more than 23,000 lb-ft torque.
Press Release Summary:
Multiple disk, spring-applied Holding Brake is intended for emergency braking on electric motors used in construction elevators, which transport both people and construction material and have potential load of 155 tons. If power or motor failure occurs or if cable breaks, brake immediately stops elevator from falling. Since safety is of highest concern, brake is mounted on output side of gearbox.

Monster Holding Brake Developed
Ogura Industrial Corporation announces the release of one of the largest production multiple disk, spring applied brakes in the industry. This new brake is capable of producing torque in excess of 23,000lb.ft. (approximately 3,000Nm).
The purpose of this brake is for emergency braking on electric motors used in construction elevators. These elevators are used in the construction of high rise buildings to transport both people and construction material. If a power or motor failure occurs or if a cable breaks, the brake immediately stops the elevator from falling.
In normal holding brake applications, the brake is usually mounted directly on the motor. This allows the smallest possible brake to be used. However, in this instance since safety is of the highest concern, the brake is mounted on the output side of the gearbox. The tremendous torque, coupled with a potential load of up to 155 tons, necessitated this type of brake.
Ogura was founded in 1938. They have since grown to be the largest manufacturer of electromagnetic clutches and brakes in the world. Ogura is ISO9001, 14001, TS16949 and RoHS and WEEE compliant.
