About Hercules
Engineered for Safety
The Hercules Anti-Jackknife system is built on innovation, precision, and real-world testing. Designed to give drivers confidence in every mile, it automatically engages the fifth wheel connection once the truck exceeds 12 mph, stopping the trailer from swinging past the critical angle that causes a jackknife.
When connected via Bluetooth, the driver’s mobile app provides instant alerts—confirming engagement, connection status, and potential risk warnings in real time. If a jackknife is imminent, the system alerts the driver and automatically prevents it.
Tested across 188 trials at the Transportation Research Center in Ohio, Hercules has proven to prevent every jackknife event, even while hauling 80,000 pounds at speeds over 70 mph. It’s not just advanced technology—it’s the future of trucking safety.
