Grounding Brushes

Copper-graphite grounding brushes are essential for safely diverting unwanted electrical currents in crane installations. Drives and frequency converters generate parasitic currents that, without proper grounding, can flow through bearings and shafts. This leads to spark erosion, accelerated wear, and ultimately costly downtime. Copper-graphite combines high electrical conductivity with the self-lubricating properties of graphite, ensuring durable, stable, and low-maintenance performance, even under heavy industrial conditions.

For precise positioning and consistent pressure on the grounding brush, the GH812 lubrication stick holder is used, which is fully suitable for copper-graphite grounding brushes. Together, they provide a reliable solution that protects bearings from harmful currents, prevents wear, and significantly reduces maintenance costs.
