To provide a crane control device and a crane capable of controlling the trajectory of swing of a suspended load in a plan view.SOLUTION: A sway prevention device 100 includes a rope length detection unit 74 that detects the rope length of a main hoisting rope, and a control unit 90. The control unit 90 calculates the sway period of the sway of a suspended load based on the detected rope length, and inputs a length command signal to a winch driving unit 81 so as to increase or decrease the rope length according to the rope period determined on the basis of the calculated sway period. The winch driving unit 81 winds and unwinds the main hoisting rope, causing the trajectory of the suspended load in a plan view to become elliptical.SELECTED DRAWING: Figure 2
【課題】平面視における吊り荷の振れの軌道を制御することが可能なクレーンの制御装置およびクレーンを提供する。【解決手段】振れ止め装置100は、主巻ロープのロープ長さを検出するロープ長さ検出部74と、制御部90とを備える。制御部90は、検出された前記ロープ長さに基づいて吊り荷の振れの振れ周期を演算し、当該演算された振れ周期に基づいて決定したロープ周期に応じて前記ロープ長さを増減させるように、ウインチ駆動部81に長さ指令信号を入力する。ウインチ駆動部81が主巻ロープの巻き取り、繰り出しを行うことで、平面視における吊り荷の軌道が楕円化する。【選択図】図2
