Abstract
A work state monitoring device for a work vehicle is provided, such that an operator can perform the work without receiving a warning. The work state monitoring device acquires a current work state of a crane using work posture detectors. A calculator calculates at least a predetermined work state corresponding to a warning load factor based on the current work state acquired by the work posture detectors. A monitor informs an operator of the predetermined work state calculated by the calculator.
