To provide a wind velocity measurement system of a crane capable of diagnosing the presence/absence of the abnormality of an anemometer.SOLUTION: The wind velocity measurement system comprises an anemometer 50 to be attached to the work attachment of the crane, a representative value calculating unit 72 during stopping to calculate a representative value during stopping which corresponds to a representative value of the wind velocity measured during the anemometer stopping when the anemometer 50 does not move due to the movement of the work attachment, an abnormality determination unit 76 to determine the presence/absence of the abnormality of the anemometer 50 based on the comparison of the measured value during moving corresponding to the value of the wind velocity measured when the anemometer 50 moves by the movement of the work attachment, with the representative value during stopping, and display devices 78, 80, 82-84 to display the determination.SELECTED DRAWING: Figure 4
【課題】風速計の異常の有無の診断が可能なクレーンの風速計測システムを提供する。【解決手段】風速計測システムは、クレーンの作業アタッチメントに取付けられる風速計50と、その作業アタッチメントの動作による風速計50の移動がない風速計停止時に計測される風速の代表値である停止時代表値を算定する停止時代表値算定部72と、作業アタッチメントの動作によって風速計50が移動しているときに計測される風速の値である移動時計測値と前記停止時代表値との比較に基づいて風速計50の異常の有無を判定する異常判定部76と、その判定を表示する表示装置78,80,82〜84と、を備える。【選択図】図4
