Rigger Basic ADC Practice Test

Which item is NOT among the tools or rigging devices that can be used to level a structural steel column?

Level Packers Tape measure Wedges

Correct Answer:

Tape measure

Explanation:

Leveling a structural steel column relies on tools that both provide a reading and enable adjustment. The level is used to show when the column is truly vertical or horizontal, a crucial real-time feedback for accuracy. Packers (shims) are added to fill gaps and raise one side to bring the column to the desired height, while wedges are used to fine-tune the seating and tilt as needed. A tape measure, though useful for checking distances or dimensions, doesn’t actively adjust or indicate level by itself, so it isn’t considered a tool for leveling.
