1. An outrigger control device comprising:
a plurality of outriggers that are provided in a traveling body, and are extendable and contractible between a non-grounding state where the traveling body is not supported by the plurality of outriggers and a grounding state where the traveling body is supported by the plurality of outriggers;
an inclination sensor that is provided in the traveling body, and is able to detect an inclination of the traveling body; and
a controller that controls an extension and contraction action of the plurality of outriggers and acquires a detection signal of the inclination sensor, wherein
the controller performs a following process for all of the plurality of outriggers:
extending one of the plurality of outriggers from the non-grounding state, and
determining the extended one of the plurality of outriggers is in the grounding state when a change of a detected value of the inclination sensor at a time of extension exceeds a preset threshold.
