The GRUNDODRILL JCS300 is one of the most advanced HDD jet drilling rigs on the market. The precisely steerable 300 kN rig is ideal for long, reproducible bores. To do so, the magazine holds 70 rods of 4.5 lengths each. Up to 6 additional rods can be reloaded simultaneously. An optimised system simplifies cable-guided drilling.

Serial assitance systems, including fully automatic drilling, rod changing and lubrication, ensure maximum efficiency for all drilling projects. For easy servicing, the JCS300 has a central lubrication system and a diesel refuelling pump for simple refuelling on the job site. The efficient, low-wear bBentonite pump is suitable for long-term use in the recycling circuit.

Another advantage of the JCS300 is its high operating comfort: thanks to the mobile HMI, the drill rig can be operated from the cab or remotely in difficult situations. The top equipment of the air-conditioned comfort cab guarantees fatigue-free working even when drilling long distances. Digital tools simplify the documentation and organisation of all drilling projects.
