Cat Detect - Collision Mitigation System is an operator assist feature designed to enhance situational awareness when reversing the machine. It utilizes an integrated and intelligent sensor array to provide reverse collision warnings, detect people, inhibit motion, and enable automatic emergency braking. Additionally, visibility into event data and safety trends is available through VisionLink™.
Rear Object Detection for wheel loaders is a two-part system providing enhanced blind spot awareness. Radar provides visual and audible alerts when objects enter a safety proximity zone, while a camera allows the operator to see what's behind the machine when reversing.
