Traffic Gates TRIZ Cases
- Rail Crossing Gate Counterbalance Using Motor Current Sensing
Motor current and speed sensing determine crossing gate counterbalance without manual torque checks, improving adjustment safety and gate reliability.
- Railroad Crossing Gate Obstruction Detection Through Motion Feedback
Motion sensing and controller feedback detect crossing gate obstructions early, preventing over-current damage and improving gate reliability.
- Gate Crossing Motor Direction Control With Relay-FET Logic
Relay-switched FET outputs reverse a gate crossing motor while adding fault detection to improve reliability and reduce maintenance.
- Gate Crossing Main Shaft Bearing Removal Without Full Disassembly
A keyed bearing tool extracts gate crossing main shaft bearings in the field without full disassembly, reducing service time and damage risk.
