Overview
HARDLOCK Nut uses a device that connects high-speed vehicles.
Implementation


- Locations where shock loads are applied when connecting and disconnecting high-speed vehicles.
- Running in a connected state is a place that receives stress during acceleration/deceleration and impact from the track.
- Locations requiring strict torque control and inspection.
Improvement
- Maintenance work such as retightening has been reduced.
- We were able to reduce the work load and reduce the total cost.
