Abstract:
A method of operating a lift truck, the method including the steps of actuating an override to move the lift truck from a safety configuration into a working configuration, positioning a load onto a front end assembly movably attached to the lift truck, disengaging the override, whereby the lift truck may move into the safety configuration once the load is removed from the front end assembly. The lift truck includes a motorized mover, a front end assembly movably coupled to the motorized mover, and a load sensor coupled to the front end assembly. The front end assembly is positionable between a safety configuration and a working configuration. The load sensor detects the presence of the load on the front end assembly. The front end assembly is moved into the safety configuration when the load sensor does not sense the load on the front end assembly.
