  • Patent number: 6246198
    Abstract: In a current-limiting setting mode, with, the motor locked and with the accelerator 4 operated fully, the detection current value of the motor provided by a current sensor CT is displayed. The operator, while observing the display, operates up/down push buttons 13 and 14 until the detection current value reaches a predetermined current-limiting value, and a duty of application of current is stored. This feature makes it unnecessary to additionarily provide a current meter, and makes it possible for only one person to perform the adjusting operation.

  • Patent number: 4994973
    Abstract: A control system for industrial use vehicles such as battery powered fork lifts in which regenerative energy is saved when the direction of travel is reversed. The control system functions to moderate the current drain on the battery. The control system comprising: a travel signal input means for generating an output signal from a travel accelerator, a cargo-handling signal input means for generating a cargo-handling signal, a monitor voltage input means for detecting a voltage at each of a plurality of monitor points and for outputting a detected signal, a sensor input means for generating an output signal from each sensor, monitor input means for generating an output signal from each monitor, and a microprocessor controller for receiving the output signals of the respective means and for outputting predetermined control signals.
