  • Actively regulated electromechanical controller for fork lift truck
    Patent number: 8096386
    Abstract: The invention relates to a method for controlling the load-handling elements of a fork-lift truck, the load-handling elements being used in the method to grip the load to be handled. The load-handling elements are operated using an electrically controlled operating device, which is controlled using an analog control voltage formed using an electromechanical controller. In addition, the analog control voltage coming from the electromechanical controller is regulated actively externally on the basis of measurement data and set criteria, before the analog control voltage formed by the electromechanical controller is conducted to the electrically controlled operating device. The analog control voltage coming from the electromechanical controller is regulated using a feed external to the electromechanical controller, in parallel with the electromechanical controller. The invention also relates to a corresponding operating system and regulating apparatus.
