Rail Fasteners TRIZ Cases
- Auto-Adjusting Rail Clamp for Multi-Profile Secure Gripping
A spring-loaded moving jaw creates three-point contact so one clamp fits varied rail profiles and stays secure during installation.
- Reconfigurable Track Working Machine for Confined Rail Maintenance
An adjustable connecting unit lets a track working machine shorten and reorient for switches, bridges, and other tight rail maintenance areas.
- Linked Impact Wrench Layout for Confined Track Processing
A linking unit splits the impact wrench into two structural units, shortening machine length for switches, bridges, and other tight track spaces.
- Rail Fastening Anchor with Breakaway Holder for Dowel Repair
A breakaway holding section keeps the rail plate fixed while the dowel body is removed through the opening for easier rail repair.
- Rail Expansion Joint Structure With Sliding Buffer Adjustment
Sliding plates, support rods, and buffer springs expand rail joint adjustment range while reducing breakage, deformation, and derailment risk.
- Rail Fastening Base Plate With Replaceable Top-Access Dowel
A through-hole base plate locks the dowel against concrete-pour buoyancy while allowing top-side removal and replacement without breaking the track bed.
