To provide a horizontal movement auxiliary device for suspended loads, a crane with it, and a horizontal movement method for the suspended loads capable of stably controlling the horizontal movement of the suspended loads.SOLUTION: A horizontal movement auxiliary device 10C has a jib operation lever 33A, a first rotation angle detecting part 52A, a first jib angle gauge 53, a driving control part 901, a derrick angle calculating part 902 of a jib, and a command value calculating part 903 of a main winding winch. The derrick angle calculating part 902 of the jib calculates the estimated derrick angle of the jib 105 based on the initial derrick angle of the jib 105 and on the rotation angle of a jib derrick winch 112 detected by the first rotation angle detecting part 52A during a derrick operation of the jib 105. The command value calculating part 903 of the main winding winch calculates the feed forward control quantity of the main winding winch 110 based on the estimated derrick angle and on the length of the jib 105.SELECTED DRAWING: Figure 3
【課題】吊り荷の水平移動制御を安定して行うことが可能な吊り荷の水平移動補助装置およびこれを備えたクレーン、吊り荷の水平移動方法を提供する。【解決手段】水平移動補助装置10Cは、ジブ操作用レバー33Aと、第1回転角検出部52Aと、第1ジブ角度計53と、駆動制御部901と、ジブ起伏角演算部902と、主巻ウインチ指令値演算部903と、を有する。ジブ起伏角演算部902は、ジブ105の初期起伏角と、ジブ105の起伏動作中に第1回転角検出部52Aによって検出されるジブ起伏ウインチ112の回転角とに基づいて、ジブ105の推定起伏角を演算する。主巻ウインチ指令値演算部903は、前記推定起伏角とジブ105の長さとに基づいて主巻ウインチ110のフィードフォワード制御量を演算する。【選択図】図3
