Hendrickson Launches Watchman Sensor System for Predictive Wheel-End Maintenance

Key Details Hendrickson unveiled Watchman, an advanced wheel-end sensor system designed to help fleets shift from reactive to predictive maintenance strategies. The technology was introduced March 17 at the Technology & Maintenance Council 2026 Annual Meeting in Nashville, Tennessee. How It Works Watchman provides real-time visibility into tire pressure and wheel-end temperature at each trailer wheel position. Hub-mounted sensors transmit data via Bluetooth to a mobile app, generating actionable alerts for slow leaks, major leaks, and low-pressure conditions. The system integrates with existing telematics platforms, making it compatible with most fleet operations. Why It Matters Tires represent one of the largest operating expenses for fleets. Even slightly underinflated tires reduce fuel efficiency, shorten casing life, and cause unplanned downtime. By pairing Watchman with Hendrickson's Tiremaax Pro inflation system, fleets gain a complete solution that automatically maintains proper tire pressure while providing intelligent diagnostics. What's Next The Watchman system expands Hendrickson's smart trailer portfolio and serves as the intelligence layer connecting the company's suspension, brake, wheel-end, and tire-inflation products. This integrated approach supports fleets in reducing costs and improving uptime.
