ABSTRACT:
An open forklift truck is provided having an elongated windshield that protects the operator from wind chills experienced when operating the truck in a cold storage environment. The windshield is a laminate having a plurality of heating elements disposed therein that are electrically connected to a control that monitors speed, battery voltage, temperature, and ambient feedback and adjusts the power supply to the windshield based on this feedback. Accordingly, the windshield is maintained at a predetermined temperature selected to limit condensation and fogging of the windshield.
