PROBLEM TO BE SOLVED: To provide a slinging device which can reliably determine an insertion completion state of a locking pin for a through-hole of a suspension piece by visual observation from a remote part with a simple structure and, moreover, can improve the accuracy of a slinging work upon rainy weather.SOLUTION: A slinging device 1 includes: a clamp which is engaged with a suspension piece 21 and, thereby, is positioned such that a locking pin 5 can be inserted to a through-hole 21a of the suspension piece 21; a driving device 6 which projects the locking pin 5 toward the through-hole 21a in such a state that the locking pin 5 is positioned on insertion allowable position for the through-hole 21a; and a check mark 71 which is mechanically coupled to a driving mechanism of the driving device 6 and can be moved between a display position of the outer side and a non-display position of the inner side with respect to the slinging device 1. Therein, when insertion to the through-hole 21a of the locking pin 5 is completed, the check mark 71 is located on the display position.
【課題】簡単な構造で、吊りピースの貫通穴に対する係止ピンの挿入完了状態を遠隔部から目視によって確実に確認することができるうえ、雨天時における玉掛け作業の精度を向上させることができる。【解決手段】吊りピース21に係合することで、係止ピン5を吊りピース21の貫通穴21aに挿入できるように位置決めするクランプと、係止ピン5が貫通穴21aに対して挿入可能位置に位置決めされた状態で、係止ピン5を貫通穴21aに向けて突出させる駆動装置6と、駆動装置6の駆動機構に機械的に連動し、玉掛け装置1に対して外側の表示位置と内側の非表示位置との間を移動し得る確認マーク71と、を備え、係止ピン5の貫通穴21aに対する挿入が完了したときに、確認マーク71が表示位置に位置する構成の玉掛け装置1を提供する。【選択図】図4
