Question 1

Before a dedicated pile driving rig arrives on site, the operator notices an area of recently placed, uncompacted fill near the proposed work area. Why is this a concern for machine arrival and setup?

Loose fill increases the load chart capacity of the rig Loose fill can cause the rig to settle or tip because it cannot reliably support the ground bearing pressure Loose fill is only a hazard for wheeled cranes, not tracked pile drivers Loose fill improves traction and is the preferred setup surface

Correct Answer:

Loose fill can cause the rig to settle or tip because it cannot reliably support the ground bearing pressure
