Description
Scully’s ST-47 Groundhog Static Ground Proving Control Unit can be used with a variety of loading operations including tank trucks, rail tank cars, aircraft refuelers and tanks to ensure that transport vehicles are properly tied to ground before and during the loading operation. These can operate in conjunction with the Scully Overfill Prevention System (ST-35® or ST-15) or as an independent ground verification unit.
Note: Includes Deadman Switch.
