To achieve efficient engaging/removing work of engaging means and to increase carrying stability and work safety in a carrier device which grasps and adjusts the fluctuation amount of a force applied by a spring to a rotary drum so as to increase work efficiency in a balancer, and suspends a product by a wire and carries it by using the balancer.SOLUTION: The balancer including a rotatable conical rotary drum on the tip of which a wire having engaging means engaged with a machine/device or a product is wound and a winding elastic band which is coaxial to the rotary drum and which applies a winding force of the wire to the rotary drum is provided with: (i) detection means for detecting the rotational speed or the rotational angle of the rotary drum rotated along with elongation/contraction of the wire; and (ii) a calculation storage device that calculates (a) the length of the wire pulled out from the rotary drum and (b) the length of the wire rewound on the rotary drum on the basis of the rotational speed or the rotational angle of the rotary drum detected by the detection means.SELECTED DRAWING: Figure 2
【課題】バランサーにおいて、スプリングが回転ドラムに付勢する力の変動量を把握して調整し、作業効率を高め、かつ、バランサーを利用する、製造物を吊りワイヤで吊って搬送する搬送装置において、係合手段の係合・取外し作業を効率化するとともに、搬送の安定性と作業の安全性を高める。【解決手段】先端に、機械・機器又は製造物に係合する係合手段を有するワイヤを巻き付けた回転可能な円錐型の回転ドラムと、該回転ドラムと同軸で、回転ドラムに上記ワイヤを巻き取る力を付勢する巻回弾性帯を備えるバランサーにおいて、(i)上記ワイヤの伸縮に伴って回転する上記回転ドラムの回転数又は回転角を検知する検知手段を備え、かつ、(ii)上記検知手段で検知した回転ドラムの回転数又は回転角に基づいて、(a)上記回転ドラムから引き出されるワイヤの長さ、及び、(b)上記回転ドラムに巻き戻されるワイヤの長さを演算・記憶する演算記憶装置を備える。【選択図】図2
