To ensure that the Shaft Grounding Assembly is in proper working condition, make the following inspections frequently:
-
Check for any cracking or breakage of components.
-
When installing or removing the rope, check the “snap in” pressure.
-
Confirm that the rope guide is not contacting the shaft. There should be approximately 1/16" (1.6 mm) between rope guide and the face of the shaft.
-
Inspect the integrity of the rope guide and attachment arms.
-
Inspect the shaft condition for any visible signs of wear, pitting, grooving, and contaminants.
-
Inspect ropes for wear and contaminants.
-
Inspect the electrical contacts on grounding ropes and in their corresponding slots in the Shaft Grounding Assembly for any wear or contaminants.
-
Inspect clearances and tightness of SGA/SCA arms to ensure there is no loosening over time, which could result in rubs and/or interference from thermal expansion.
