In 2010, with the permission of the national nuclear power equipment system software, two independently developed and designed power column type nuclear power plant gearboxes were invested in the assembly line industrial base of the Hongyanhe and Ningde nuclear power plant engineering projects in Liaoning Province and Fujian Province, respectively.

Needle wheel deceleration is a device that slows down the rotation of an electric motor to the required number of rotations and obtains a high torque.

A reducer is a relatively high-precision mechanical equipment, which is used to reduce the speed ratio and increase torque.

The needle gear reducer is based on the basic principle of using a rotary wheel line needle tooth combination and a large planetary transmission system, so it is generally also known as a large planetary hard tooth surface reducer.

The market is applied to major national engineering projects such as the South to North Water Diversion Project, West to East Gas Pipeline, Three Gorges Project, Xichang Satellite Launch Center, Beijing Olympic Stadium, and World Expo Park.
