Essig Hercu 55mm Impact Mole | Horizontal Boring Tool | High-Accuracy Soil Displacement

The Essig Hercu 55mm Impact Mole is a high-performance soil displacement tool engineered for the trenchless installation of underground services such as product pipes and conduits. Driven by a high-frequency internal piston powered by a compressed air generator, the Hercu creates a precise bore by displacing surrounding soil. This displacement method allows for immediate pipe introduction during the mole run or subsequent installation. All Essig units are designed with a fully reversible mechanism that operates without the need for cables or mechanical turning; operators simply manage the compressed air supply and hose tension to reverse direction.

How does the Essig Hercu 55mm facilitate underground boring?

The tool utilizes compressed air at 6-7 bars to drive an internal piston through the body casing, creating a displacement bore through the soil. This process allows for the direct installation of conduits or product pipes up to DN40 in diameter with high directional accuracy.

Is the 55mm Hercu mole reversible during operation?

Yes, all Essig machines are fully reversible without requiring manual turning or cables. Technicians can initiate the reverse cycle by turning off the compressed air supply and pulling the hose while reintroducing air, facilitating safe tool retrieval in varying soil conditions.

What are the primary operational benefits of the Essig mole?

The Hercu 55mm offers a short preparation time and requires only 1 to 2 operators, significantly reducing on-site labor costs. Its design features no thrust bearing and minimal profile overlap, ensuring accurate boring in restricted workspaces.

• For smaller service applications, consider the 45mm Essig Impact Mole for bores up to DN32.
• Compatible with standard mobile air compressors and generators.
• Available with expanders for increased bore diameters where soil conditions permit.
