97 mm Pneumatic Underground Boring Machine
The ALM 97 Thrust Boring Machine is a powerful trenchless tool designed to install pipes and cables without digging. It creates a straight and clean horizontal bore under roads, sidewalks, and other structures—without disturbing the surface above.
This machine is part of our trusted Allame Ground Mole series, built for fast and safe underground installations. With its 97 mm bore diameter, the ALM 97 is ideal for laying gas pipes, water lines, telecom cables, and electrical conduits.
How It Works
The ALM 97 runs with compressed air at 6 bar pressure. It uses a pneumatic forward-and-back motion to move through the soil. This motion pushes the machine ahead, creating a tunnel in the ground.
The ALM 97 is best suited for medium-size utility lines. It works in many soil types, including clay, sandy soil, and soft mixed ground. Its steel body is tough and made for long-term use in the field.

Why Choose ALM 97?
The ALM 97 is a top choice for contractors who need speed, accuracy, and reliability. It reduces the need for open trenching, which saves time and money.
