<p>An industrial fork lift truck comprising an electric motor (3), a motor controller (2) for controlling the electric motor (3) and a truck computer (1) for controlling the motor controller (2), said truck computer (1) comprising a detection system (5) for detecting spinning and/or locking of the drive wheel of the truck characterized in that the detection system (5) is arranged to receive a signal corresponding to the momentary torque current of the motor (3); and further comprising:
-a calculation unit (12) for calculating the theoretical torque current of the motor (3);
-a comparison unit (13) for comparing the theoretical torque current of the motor (3) and the momentary torque current of the motor (3), wherein the truck computer is arranged to reduce the acceleration or the deceleration of the truck if there is a difference between the theoretical torque current of the motor (3) and the momentary torque current of the motor (3).</p> |
