TELESCOPIC BOOM AND CRANE DEVICE
PROBLEM TO BE SOLVED: To provide a telescopic boom which can eliminate the change of a suspension position of a suspended object by telescopic motion, and eliminate the complexity of position control of the suspended object, which is generated along with the movement of a take-out position of a wire.SOLUTION: A telescopic boom comprises: a first arm 11 having a first wire sheave 16A, to which a wire WR connected to a suspended object is hung, near the tip; a second arm 12 provided along the first arm 11 so as to move forward and backward, from which the tip of the wire is taken out; a slider 27 provided movably along the first arm; engagement means 21, 26, 32 for extending and contracting the second arm along with the movement of the slider, which engage with both the first arm and the second arm; an intermediate wire sheave 33R provided in the slider for winding the wire that is hung to the first wire sheave and sending the wire to the second arm; and drive means 31 for moving the slider.
【課題】伸縮により吊下物の吊り下げ位置の変化をなくし、ワイヤの取り出し位置の移動に伴って生じる吊下物の位置制御の煩雑性を解消することができるテレスコブームを提供する。【解決手段】テレスコブームは、吊下物に接続されたワイヤＷＲが掛けられた第１ワイヤシーブ１６Ｒを先端近傍に有する第１アーム１１と、前記第１アーム１１に沿って進退可能に設けられ、前記ワイヤの先端が取り出される第２アーム１２と、前記第１アームに沿って移動可能に設けられたスライダ２７と、前記第１のアームと第２のアームの双方に噛合し前記スライダの移動に伴って前記第２アームを伸縮させる噛合手段２１，２６，３２と、前記スライダに設けられ前記第１ワイヤシーブに掛けられた前記ワイヤを巻き回して前記第２アームに送る中間ワイヤシーブ３３Ｒと、前記スライダを移動させる駆動手段３１とを有する。【選択図】図４
