Benefits of Spherical Hobs in Hydromill Cutting

1. Cost Savings: The use of spherical hobs leads to significant reductions in expenses related to hydromill cutting in hard rock, facilitating faster project delivery.

2. Streamlined Processes: The absence of a need for precutting holes simplifies machinery requirements and construction workflows.

3. Prolonged Operating Duration: The hob-tooth hydromill wheel supports continuous operation for up to 100 hours, reducing the need for frequent hydromill lifts and extending project timelines while decreasing labor demands.

4. Reduced Maintenance Needs: Operating with less strain on the gearbox, the hydromill module enhances efficiency and minimizes both maintenance time and costs.

5. Low Environmental Impact: This technology causes minimal disruption to the ground, making it ideal for projects located close to existing infrastructures.

6. Improved Cutting Deflection: The design optimizes deflection capabilities, making it effective for hydromill cutting in challenging rock conditions.

7. Precision in Operations: Trenches can be aligned vertically with an accuracy of up to 1‰, ensuring high-quality outcomes.

8. Fuel Efficiency: The system achieves over 20% fuel savings, averaging 73L/h with a CAT C18 engine, contributing to energy efficiency and environmental friendliness.

To keep the Spherical hob work, sufficient downforce must be exerted on it. This is the basis for the success of the Spherical hob. This solution mainly adds a pressure device between the cutting module body and the wheel, so that modifications can be made on the basis of the existing module with low cost. After the downforce increased, the original gearbox's load-bearing capacity was insufficient, and a larger gearbox needed to be redesigned. Due to the limitation of the wheel size, the original shock absorber ring should be removed. This solution places the shock absorbing device between the motor reducer and the module.
