Customer challenges
with industrial cranes

Industrial cranes are heavy-duty machines used in a wide range of industries to lift and move heavy loads. These cranes are often powered by electric motors, and their operation can have an impact on power quality.

One of the main effects is voltage sag, which occurs when the voltage in the electrical system drops below the normal level. This can happen when the crane starts up, when it is carrying a heavy load, or when it stops suddenly. Voltage sag can cause problems for other equipment in the electrical system, as it can cause computers to shut down or equipment to malfunction.

Industrial cranes can also generate harmonics if they are fed through a Variable Frequency Drive (VFD) or a DC-drive. Harmonics can cause problems for other equipment in the electrical system, as they can cause overheating, insulation breakdown, and various other issues. They can also cause interference with communication systems, such as radios and telephones.

By mitigating power quality issues, we can ensure that industrial cranes can continue to be used safely and effectively in a wide range of settings.
