Practical Notes

Ensure piling rigs are erected on firm, leveled ground or supported by heavy timber mats to prevent overturning during operation.

Wire ropes, sheaves, and lifting tackles are subjected to extreme dynamic loads and must be inspected daily before starting pile driving.

Open boreholes for cast-in-situ piles must be securely covered or barricaded immediately after boring to prevent workers from falling in.
