PROBLEM TO BE SOLVED: To provide a control device for controlling drive of first and second winches so as to move a common load safely and quickly.SOLUTION: A control device comprises: first speed adjustment units 27A, 28A and second speed adjustment units 27B, 28B that adjust driving speeds of first and second winches 20A, 20B respectively; a displacement detection unit for detecting relative displacement from initial states of connection positions P1, P2 of first and second winch ropes 21A, 21B to a load 16; a speed control device 40; and an operation device 30 for commanding a designated speed. The speed control device 40 performs control of decreasing the magnitude of the relative displacement detected by the displacement detection unit by giving a speed same as the designated speed to one of a first speed command and a second speed command to the first and second speed adjustment units and giving a speed lower than the designated speed to the other.SELECTED DRAWING: Figure 1

    【課題】共通の負荷を安全にかつ迅速に動かすように第1及び第2ウィンチの駆動を制御する制御装置を提供する。【解決手段】制御装置は、第1及び第2ウィンチ20A,20Bの駆動速度をそれぞれ調節する第1速度調節部27A,28A及び第2速度調節部27B,28Bと、負荷16への第1及び第2ウィンチロープ21A,21Bの接続位置P1,P2の初期状態からの相対変位を検出する変位検出部と、速度制御装置40と、指定速度を指令するための操作装置30と、を備える。速度制御装置40は、第1及び第2速度調節部に対する第1速度指令及び前記第2速度指令のうちの一方に指定速度と同等の速度を与え、他方には指定速度よりも低い速度を与えることにより、変位検出部により検出される相対変位の大きさを減少させる制御を行う。【選択図】図1
