<p>PURPOSE:To obtain a slip preventing apparatus which has high adhesive performance with energy-saving by storing a vibration mode in adavnce in a computer, and controlling the voltage and current of a main motor by a command signal from the computer when the slip occurs. CONSTITUTION:When a slip phenomenon occurrence is detected by the output signal of an acceleration detector 6, a computer 5 applies a control signal for a vibration mode stored in advance to an electric circuit 34 to control the voltage and current of a main motor 10. Further, the computer operates to open a discharge control valve 17, to scatter sand in a sand box 22 from a tube 21. In addition, the computer operates to open or close a valve 23 to vary the axial load of the slipping wheel.</p> |
