What is the maximum slope for setting up a digger derrick as per ANSI A 10.31?

The correct response regarding the maximum slope for setting up a digger derrick as per ANSI A 10.31 is indeed 5°. This standard is crucial for ensuring safety and stability while operating digger derricks, which are used for tasks such as digging holes and setting poles.

A slope greater than 5° can compromise the stability of the digger derrick, increasing the risk of tipping or other accidents, especially when the machine is in operation. Adhering to this maximum slope limit helps ensure that the equipment remains level, providing a solid base for the boom and any loads being handled.

Using a measurement of 5° reflects careful consideration of the equipment's center of gravity and its design limitations. It's essential for linemen and operators to be fully aware of and comply with these guidelines to maintain safety on the job site while performing lineman duties.
