Frequently Asked Questions
Q&A About Hercules Anti-Jackknife System?
How does the Hercules Anti-Jackknife system work?
It automatically engages a steel bar into the fifth wheel when the truck reaches 12 mph, locking the trailer from swinging past a critical angle.
Does the driver need to do anything to activate it?
No, the system engages automatically at the correct speed. However, the driver can manually activate it at lower speeds if needed.
Can the system disengage automatically?
Yes, the system disengages when the vehicle slows below 12 mph unless the manual override is in use.
What happens if a jackknife starts to occur?
The app immediately alerts the driver, and if no corrective action is taken, the system engages to prevent the jackknife.
Is the system compatible with all trailers?
Yes, the system is compatible with all trailers, but it can only be connected to one trailer at a time.
How does the app connect to the device?
Via Bluetooth, with an automatic pairing feature when the driver is within 25 feet of the trailer.
What does the app show the driver?
Real-time notifications for connection status, device engagement, and jackknife alerts.
Can the app be used on both iOS and Android?
Yes, the app will be available on both platforms.
What if the Bluetooth connection drops?
The app will alert the driver, and the system will remain engaged until the connection is re-established or the vehicle slows.
Can a driver pair with multiple trailers?

Is there a risk of false engagement?
No. The system uses precise speed data and locking mechanics to prevent unnecessary activation.
Can the system be manually overridden in emergencies?
