  • Forklift controller
    Patent number: 5592817
    Abstract: The forklift controller changes the speed of the actuator, corresponding to the operational angle of the lift lever, and then changes the vehicle speed, corresponding to the amount of depression of an accelerator. This allows the controller to control the throttle opening corresponding to the operational angle of the lift lever, and together controls the amount of depression of the accelerator. During running without being loaded, the forklift controller changes the vehicle speed, corresponding to the amount of depression of the accelerator, and together determines the number of revolutions of the engine to the throttle opening so that the optimum fuel consumption can be obtained. The controller controls the throttle opening and speed ratio so that the vehicle speed and number of revolutions of the engine can be controlled.
