BM60 Pneumatic Impact Mole for Trenchless Pipe Ramming

Product Overview

The BM60 Pneumatic Impact Mole is a compact and efficient trenchless boring tool designed for underground pipe installation without surface excavation. Powered by compressed air, it delivers stable low-frequency impact energy to penetrate soil layers quickly and accurately, making it ideal for short-distance pipe ramming projects in urban and municipal construction.

This model is especially suitable for installing Ø50 mm pipes, with the flexibility to accommodate one size smaller or larger pipe diameters depending on jobsite requirements.

Technical Specifications – BM60

Note:
Each BM60 impact mole can directly install three pipe sizes:

• Standard pipe diameter (50 mm)

• One size smaller than standard

• One size larger than standard

Working Principle

The BM60 Pneumatic Impact Mole operates using compressed air to drive an internal piston, which repeatedly strikes the anvil inside the tool body. The generated impact force propels the mole forward through the soil, forming a straight borehole.

Once the mole exits at the receiving pit, pipes can be installed by:

• Pulling pipes through the borehole using a steel wire rope, or

• Installing pipes simultaneously using a pipe adapter during boring
