BM series pneumatic mole can be used in short distance horizontal pipe laying in soilayer, layer with few pebbles or layer withsome boulders. ts tront impact head independent of the mole body fonward impact, can easily break pebbles and boulders. Whenencountering an impassable obstacle, turn the hose to the right to let the mole return.

The pneumatic spear is essentially a low-frequency, low-pressure pneumatic impact device. It is powered by compressed air, which drives the hammer inside the cylinder to strike the anvil, thereby causing the spear body to be pushed into the stratum. Once the spear body emerges from the stratum, the pneumatic spear body is removed, and the steel wire rope is connected to the air pipe. The air pipe is then pulled back to bring the steel wire rope into the hole, and finally, the steel wire rope is used to pull the pipeline to be laid into the hole to achieve non-digging pipeline laying.
