のためこれを支持する構造も単に板金構造となっていた
。The canopy of a conventional excavator was considered to have a lightweight structure because it was only necessary to provide habitability. Therefore, the structure supporting it was simply a sheet metal structure.
掘削機のキャノピは転倒保護構造にするようキャノピ強
度の規制が実施されようとしており、最近のキャノピは
、キャノピ内に補強枠を入れてたとえ掘削機が転倒して
もキャノピが壊れることがなく、運転者を保護できるよ
うにしたものが作られるようになってきた。Regulations on the strength of excavator canopies are about to be implemented, requiring them to have a structure that protects them from falling over.Recent canopies have a reinforcing frame inside the canopy, which prevents the canopy from breaking even if the excavator falls over. Vehicles that can protect drivers have begun to be made.
このためキャノピの従来の支持構造では強度不足となっ
て上記キャノピを有効に支持することができなかった。For this reason, the conventional support structure for the canopy lacks strength and cannot effectively support the canopy.
