Manual Release Lock Security
JOST’s signature Manual Release locking mechanism is one of the original features in all other JOST fifth wheel products, setting the industry standard for fifth-wheel construction and functionality. With just four moving parts, JOST’s Manual Release Lock Security ensures ultimate safety and simplicity for secure, efficient hauling.
- Standard Handle Features
- Retractable Handle Features
The JOST UBK 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.
- Cushion ring in throat reduces wear on the kingpin and absorbs impact.
- Full size release handle for easy manual release.
The dual-sensor system is connected to the Go/No-Go indicator light located next to the handle. A proper coupling with the handle and kingpin in the locked position will be lit up as green or “Go light”. If the system does not detect the handle and/or kingpin in the proper locked position, the light will flash red or “No-Go light”
Green/Red/White Indicator Light with audible alert.
Throat illumination light for superior lock bar visibility.
