Devices Secured To Track TRIZ Cases
- Rail Derailer Geometry for Higher-Speed Portable Installation
An angled wheel-deflecting surface and segmented clamping let a rail derailer handle higher speeds without sacrificing portability or integrity.
- Low Profile Portable Derail Segmentation and Nesting
Segmented low profile derail prevents locomotive push-off while enabling single-worker handling without special tools.
- Portable Derailing Device With Angled Deflecting Surface
An angled deflecting surface and clamping mechanisms enable high-speed derailment while maintaining portability.
- Double Point Derail Switch Inversion for Track Bump Elimination
A double point derail switch lifts railcar wheels using an outside and inside switch rail configuration.
- Low Profile Derail for Locomotive Safety
A low profile derail assembly uses an angled bar and clamp to secure the rail while maintaining a height under three inches.
- Derail Assembly with Angled Bar and Tie Spacer
Angled derail bar engages wheels while rigid hooks secure the unit to rails, preventing pilot dislodgement.
- Hinged Derail Torsion Spring Manual Lifting Assistance
A torsion spring mounted on a hinged derail base provides upward lifting force to the pivotally mounted shoe, reducing operator back injury risk.
