To provide a swing control device for a working machine capable of accurately swinging an upper swinging body at a target swinging speed, and a working machine equipped with the same.SOLUTION: A swing control device 100 is used for a crane 10 having an upper swing body 12, a lower travel body 14, a swing drive unit 101, and an attachment 10S. The swing control device 100 has a controller 110. The controller 110 operates the swing drive unit 101 based on feed-forward control so that the upper swing body 12 swings at a target swing speed. The controller 110 generates a correction command signal by correcting a reference command signal set in advance corresponding to a predetermined target swing speed based on information on fluctuation factors that cause the swing speed to vary, and inputs the correction command signal to the swing drive unit 101.SELECTED DRAWING: Figure 2

    【課題】上部旋回体を目標旋回速度で精度良く旋回させることが可能な作業機械の旋回制御装置およびこれを備えた作業機械を提供する。【解決手段】旋回制御装置100は、上部旋回体12と下部走行体14と旋回駆動部101とアタッチメント10Sとを有するクレーン10に用いられる。旋回制御装置100は、コントローラ110を有する。コントローラ110は、上部旋回体12が目標旋回速度で旋回するようにフィードフォワード制御に基づいて旋回駆動部101を作動させる。コントローラ110は、所定の目標旋回速度に対応して予め設定された基準指令信号を、前記旋回速度を変動させる変動要因に関する情報に基づいて補正して補正指令信号を生成し、当該補正指令信号を旋回駆動部101に入力する。【選択図】図2
