WatchGUARD

In-Cab Hazard Awareness

Targeted protection when seconds matter. WatchGUARD monitors hazards and alignment conditions in real time from the cab, improving low-visibility awareness so operators can identify risk sooner and respond with more confidence. When risk is detected and identified, WatchGUARD can automatically brake for obstruction scenarios.

Part of YardGUARD’s real-time safety intelligence system – helping teams verify conditions and proceed with confidence.
