The EN 474-3:2006+A1:2009 standard offers a comprehensive framework focusing on the safety requirements specific to loaders used in earth-moving machinery. Its scope is well-defined, centering on significant hazards and hazardous situations relevant to loaders, as established by EN ISO 6165:2006. This makes the standard particularly relevant for manufacturers and operators who need to ensure the safe use of loaders while adhering to the expected standards of performance and safety. One of the key strengths of this standard is its thorough approach to addressing not only intended use but also foreseeable misuse scenarios. By considering various applications, including fork application, single heavy object handling, object handling, and log handling, the document provides a robust safety guideline adaptable to diverse operational contexts. This inclusivity fosters a safer working environment as it covers the full spectrum of potential risks associated with loader operations. Moreover, EN 474-3:2006+A1:2009 serves as a complementary document to the common requirements established in EN 474-1:2006, ensuring that manufacturers and operators are well-informed of both general and specific safety measures. By specifying technical measures tailored to the unique risks associated with loaders, this standard enhances the ability to effectively eliminate or mitigate these risks during commissioning, operation, and maintenance phases. Importantly, the standard's delineation of responsibility clarifies that it does not apply to loaders produced prior to its publication, which aids in establishing a clear regulatory framework for newer models and ensuring safety compliance in current manufacturing practices. Overall, the relevance of EN 474-3:2006+A1:2009 in enhancing safety standards around loaders cannot be overstated, making it an essential document for industry stakeholders committed to maintaining high safety protocols in earth-moving machinery.
標準EN 474-3:2006+A1:2009は、「地面を動かす機械 - 安全性 - 第3部: ローダーの要求事項」に関するものであり、ローダーに関連する重要な危険、危険な状況、及び事象を扱っています。この規格は、EN ISO 6165:2006で定義されたローダーが意図された通りに使用され、製造者が合理的に予見できる誤使用の条件下でのリスクを対象にしています。 この標準の大きな強みは、フォーク適用、単一重物の取り扱いや、物体取り扱いおよび丸太取り扱いの場合におけるリスクに関する具体的な要求事項を含んでいる点です。また、EN 474-1:2006で定められた共通の要求事項とは補完的であり、ローダーに特有の要求を追加または置き換えています。これにより、ローダーに特有の安全性の要件が満たされることになります。 さらに、本規格は、ローダーの commissioning、運転及びメンテナンスの際に生じる重要な危険、危険な状況、及び事象を低減または排除するための適切な技術的措置を特定しており、実用的な指針を提供しています。これにより、業界における運用の安全性が大幅に向上すると期待されます。 なお、このヨーロッパ規格は、CENによる公表日以前に製造されたローダーには適用されません。この点にも注意が必要です。全体として、EN 474-3:2006+A1:2009は、ローダーの安全性に関する包括的な要求事項を提供しており、その関連性と重要性は高いと言えます。
SIST EN 474-3:2007+A1:2009 표준은 로더의 안전성에 중점을 둔 중요한 문서로서, EN 474 시리즈의 필수적인 부분을 구성하고 있습니다. 이 표준은 로더 사용 시 발생할 수 있는 주요 위험 요소 및 위험 상황을 포괄적으로 다루고 있으며, EN ISO 6165:2006에서 정의된 로더의 정의와 함께 의도한 사용 및 제조업체가 합리적으로 예견할 수 있는 오용 조건에서의 안전 요건을 규명하고 있습니다. 본 표준의 강점 중 하나는 포크 적용, 단일 중량물 취급, 물체 취급 및 목재 취급과 같은 다양한 작업에 대한 구체적인 요구사항을 명시한다는 점입니다. 이는 로더의 다양한 운용 환경을 고려하여 안전성을 극대화하는 데 기여합니다. 또한, 이 표준은 EN 474-1:2006에서 제정된 일반 요구사항에 보완적인 역할을 하며, 중복된 요구 사항 없이 로더에 대한 추가적이거나 대체적인 요구사항을 제공합니다. 로더의 설치, 운영 및 유지보수 과정에서 발생할 수 있는 상당한 위험 요소를 제거하거나 줄이기 위한 기술적 조치를 명확히 규정하고 있어, 해당 기계 장비의 안전성을 향상시키는 데 필수적입니다. 이러한 구조적 접근은 사용자 및 작업자를 보호하고 잠재적인 사고를 예방하기 위한 체계적인 기반을 제공합니다. 마지막으로, 이 유럽 표준은 2006년 발행 이전에 제조된 로더에는 적용되지 않는 점을 명시하여, 최신 기술과 안전 기준을 기반으로 한 현행 로더에 대한 안전 요구사항을 설정하고 있습니다. 전반적으로 SIST EN 474-3:2007+A1:2009 표준은 로더의 안전성 및 효율성을 향상시키는 데 중요한 초석이 될 것으로 평가됩니다.
