Ground Ball, truck-mounted electronic ground proving ball for Independent Grounding System.
- Part of the original patented Scully Groundhog static ground verification system.
- “Smart” circuitry verifies proper connection is made before loading can begin; if the ground connection is broken during loading operation, the operation ceases.
- With the Scully Ground Bolt, only one connection is needed for overfill prevention and ground verification when using ST-47 Groundhog and Scully Overfill Prevention Control System.
- Special “smart” Ground Ball is used for independent ground verification where Scully overfill prevention system is not in use.
