SIST EN 474-5:2007/kprA1:2008

Overview

SIST EN 474-5:2007/kprA1:2008 is a European standard prepared by CEN/TC 151 focusing on the safety requirements for hydraulic excavators, a critical category of earth-moving machinery. This amendment supports the original EN 474-5:2006 and aligns with the essential health and safety requirements of the EU Machinery Directive 2006/42/EC. The standard is designed to ensure hydraulic excavators meet safety benchmarks that protect operators and those working around these powerful construction machines.

Key Topics

• Scope and Purpose
  The standard specifies safety features and protective measures specifically applicable to hydraulic excavators. It addresses structural safety, operational controls, and protective systems necessary to reduce the risk of accidents during excavation tasks.

• Falling-object Protective Structure (FOPS)
  Walking excavators must be equipped with a FOPS compliant with EN ISO 3449:2005, level II. This structure minimizes the risk of injury from falling debris or objects, a common hazard on construction sites.

• Swing Service Brake Requirements
  The amendment clarifies control parameters for the swing service brake, ensuring enhanced operational safety. It limits the brake’s deceleration characteristics to prevent sudden or uncontrolled movements, improving machine stability.

• Compliance with EU Directives
  Annex ZB outlines the relationship between this standard and the EU Machinery Directive 2006/42/EC. Compliance with EN 474-5 confers a presumption of conformity with essential legal requirements covering safety, thereby facilitating regulatory approval and market access within the European Union.

Applications

SIST EN 474-5:2007/kprA1:2008 is intended for manufacturers, safety engineers, and regulatory bodies involved with hydraulic excavators used in:

• Construction and Civil Engineering
• Landscaping and Earth-moving Projects
• Mining and Quarrying Operations
• Infrastructure Development

By following this standard, organizations ensure that hydraulic excavators meet rigorous safety criteria, thereby reducing the potential for workplace injuries and equipment damage. It also helps in risk assessment, safety audits, and compliance verification for hydraulic excavators before they enter service.
