Ground, mats, and outriggers

The controlling entity has to give you ground that can take the crane, mats, and the load. If the dirt is junk, that is not an operator-only problem — but you still do not set up on it.

Floats need area. Timber mats and cribbing spread the pounds per square foot. A shiny pad on mud is a punch-through waiting.

Level means level. A machine a couple degrees out of level is not on the chart you think it is, and the boom gets side-load.

If the sheet says fully extended outriggers, short-jacking is a different sheet or no pick.
