What must NOT be attached to equipment used for pile driving?

When considering equipment used for pile driving, it is important to understand the specific functions and safety implications of attaching additional components. In this context, a jib, which is a horizontal arm that extends from the mast or tower of a crane, can create stability issues and complicate the lifting process when used with pile driving rigs. Pile driving requires precise control and stability, and the addition of a jib can introduce unnecessary risk by altering the center of gravity and increasing the likelihood of instability during operation.

Counterweights, winches, and pulleys play important roles in enhancing the effectiveness and safety of pile driving equipment. Counterweights help balance the rig and prevent tipping during operation. Winches are essential for lifting and lowering the pile, making them critical for the operation. Pulleys can assist in managing load direction and adding mechanical advantage. Together, these components align well with the fundamental requirements for safe and effective pile driving operations, while a jib does not appropriately fit into that system, emphasizing why it should not be attached.
