Title:
OUTRIGGER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/166720
Kind Code:
A1
Abstract:
The present invention provides an outrigger control device that can detect grounding with fewer sensors and eliminate wiring for connecting a movable part to a controller, and is profitable in cost and reliability. An outrigger control device (A1) comprises: a plurality of outriggers (30) that is provided in a traveling body (10) and extendable/contractible between a non-grounding state where the traveling body is not supported and a grounding state where the traveling body is supported; an inclination sensor (310) that is provided in the traveling body and can detect inclination of the traveling body; and a controller (100) that controls an extension/contraction action of each outrigger and acquires a detection signal of the inclination sensor (310). Further, the controller is provided with a grounding determination processing unit (101) that controls the outriggers to perform a predetermined grounding determination action and determines whether or not each outrigger is in the grounding state on the basis of the detected value of the inclination sensor at the time.
