Characteristic One：The shiftable alloy blade fastened into the inserting trough of the face milling cutter. So even the hard sundries hidden in the ground could lead to the alloy sheet break or lost, we can supplement in time. This machine could add12,15,18 double blades freely.

Characteristic Two: The front and back axletree pedestal of the machine not collocated in line and they could work across, which cleanse the cement residue completely. It lessens repeated wear while increases efficiency.

Characteristic Three: Implement the only cleaning machine dynamo vertical installation in China and adopt umbrella shape gear wheel shifting .The structure is reasonable while drive strong.

Characteristic Four: Independent research and produced steel axletree pedestal, matched with double row center regulated axletree 2207.There are two rows of steel balls, which are solid,wearable and of lifespan.

Characteristic Five: Support line devince could make the power wire away from the machine, which spares a worder. Pull it forward and backward during working. The wire could be move freely when it’s inconvenient next to the wall. It won’t hurt your hands with three handles. Lay it down by lifting up the pole ,raise the pole flatly and turn back will automatically lock up.

Characteristic Six: The shock absorption of the handle could lessen the violent shake caused by hardness of cement blocks and uneven ground.

Characteristic Seven: Folded wheel can be moved conveniently ,so it can be disassembled and installed conveniently.
