Your questions — our technical solutions

The 9KW725 machine is designed to serve the power generation sector and heavy machinery industry. It is ideal for balancing:

  • Rotors of high-power steam and gas turbines.
  • Shaft assemblies of hydroelectric units.
  • Heavy-duty turbogenerators.
  • Large-scale assemblies for power plant maintenance facilities.

Thanks to its pendulum suspension and support rollers with cylindrical surfaces, the machine handles massive components with care, completely eliminating the risk of “scoring” or damage to the rotor’s precision journals.

Yes, the 9KW725 machine is specifically designed to handle such loads. This equipment is capable of effectively balancing rotors weighing up to 60 tons. Despite the enormous weight of the workpieces, the machine does not require a special foundation, which is a unique feature. The measurement process takes place at low, safe rotational speeds, which reduces the load on the machine’s components and ensures maximum safety when working with critical masses.

The machine’s design allows it to handle parts up to 12,000 mm in length. We can manufacture an extended version of the bed (over 12 m) for balancing long shafts.

Furthermore, the mobile version of the 9KW725 model can be transported on a special truck platform, allowing the machine to be delivered directly to the site (for example, to a thermal power plant or a nuclear power plant) to perform work at the unit’s operating location.

A high-precision pendulum suspension and a state-of-the-art measurement system enable us to achieve a minimum residual specific imbalance of 1 g·mm/kg.

This ensures superior balancing quality for 60-ton rotors in accordance with international accuracy standards. This result significantly reduces the vibration load on the bearings and foundations of turbine units, extending the equipment’s overhaul intervals.

Yes, the machine is set up for a new product type by the operator using trial runs with calibration weights.

This approach offers several key advantages for B2B production:

  • Maximum Sensitivity: Calibration allows adapting the measuring system to the specific geometry and mass of the rotor, minimizing error.

  • Accuracy Control: The operator can verify and confirm measurement accuracy at any time, eliminating the accumulation of errors during long-term operation.

  • Flexibility: The machine maintains reference-level accuracy even with non-standard or complex parts, as the system is tuned to the actual response of the specific rotor.
