Properties specific to PileDriveHammer:

Property or Attribute Name (Type)	Definition	Cardinality
hammerKind (gml:CodeType)	The general classification of the hammer, e.g., drop hammer, diesel hammer, hydraulic hammer.	0..1
hammerType (gml:CodeType)	The specific model or type of hammer within the broader category.	0..1
hammerAction (gml:CodeType)	The mechanism by which the hammer delivers energy to the pile, e.g., single-acting, double-acting, differential-acting.	0..1
ratedEnergy (eml:EnergyMeasureExt)	The manufacturer's specified maximum energy per blow the hammer can deliver.	0..1
ratedStroke (eml:LengthMeasureExt)	The manufacturer's specified maximum distance the ram travels in a single blow.	0..1
ramWeight (eml:ForceMeasureExt)	The weight of the ram (the part that strikes the pile).	0..1
hammerWeight (eml:ForceMeasureExt)	The total weight of the hammer assembly.	0..1
anvilWeight (eml:ForceMeasureExt)	The weight of the anvil (the part that rests on the pile).	0..1
pistonArea (eml:AreaMeasureExt)	The cross-sectional area of the piston (if applicable).	0..1
strikerPlate (StrikerPlatePropertyType)	The properties of the striker plate (the piece that makes direct contact with the pile).	0..1
blowsPerMinuteMin (positiveInteger)	The minimum blows per minute that the hammer can achieve.	0..1
blowsPerMinuteMax (positiveInteger)	The maximum blows per minute that the hammer can achieve.	0..1

Key Points:

• Cardinality (0..1): Most of these properties are optional and may not be applicable to every type of hammer. You would record the ones that are relevant for the specific hammer being used.
• Data Types: The linked data types provide specific information on how to measure and format these properties. It's crucial to adhere to these types to ensure data consistency.
• StrikerPlatePropertyType: This is likely a reference to another section in your documentation where the properties of the striker plate are defined in more detail.
