As shown in Publication No. 62-18618, a round pipe receiver is buried in the upright wall, and a round bar hoist is connected to the end of the wire rope for pulling the lifting machine.
When lifting and reversing concrete products,
The hanging tool is inserted and locked into a locking hole formed in a hollow portion of the receiver.
（考案が解決しようとする問題点）
しかしながら、該吊具は丸パイプの平滑な内周
面と丸棒の平滑な外周面との面接触による摩擦力
によつて該受具に係止されているだけであるた
め、十分な係止力が得られず、コンクリート製品
