StopGUARD

Crew Emergency Stop & Video

StopGUARD strengthens protection during critical moves by giving crews emergency braking capability — including automatic stop activation in a person-down event — and live visual support that reduces blind spots when seconds matter. Crew-worn cameras provide live views to the operator through the YardGUARD in-cab display, reducing reliance on radio-only communication.

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