クレーンで吊り下げた掘削機を使って、大きな橋梁を解体する作業現場の様子です。
掘削機が乗っている足場が崩れても安全という工法なのでしょうが、かなりレベルの高い技術がないと少し危険な気もします。

A work site where a large bridge is dismantled using an excavator suspended by a crane.
The construction method is probably safe even if the scaffolding on which the excavator is on collapses, but I feel that it is a little dangerous without a fairly high level of technology.
