Feature
¡¤ Inside building grouting reinforcement and basement
water leak age interception in work.
¡¤ The noise level reduced since the hydraulic motor
takes charge of revolution strength.
¡¤ Work is more convenient as one may revolve the
revolution panel beside the hydraulic speed reduction instrument.
¡¤ Since the length of 'rod' work is becoming longer
compared to the boring machine, the work is faster. |
