Manual Release Lock Security

With just four moving parts, JOST’s Manual Release Lock Security ensures ultimate safety and simplicity for secure, efficient hauling.

The LockTronic Security System is a self contained battery-powered LED that confirms the fifth wheel is properly secured. When properly locked, the LockTronic flashes a bright LED light. Operators can see the light from any point between the cab and the landing gear crank.

The JOST USK Sensor Wheel allows the driver to know when the fifth wheel is properly and safely coupled from inside the cab by sending a signal to a display in the cab that illustrates when the wheel is properly coupled.
- Visual lock indicator for proper locking.
- Automatic secondary lock to ensure security.
