SIST EN 474-3:2007/kprA1:2008

Overview

SIST EN 474-3:2007/kprA1:2008 is a European standard developed by CEN Technical Committee 151 focusing on the safety requirements for loaders used in earth-moving machinery. This amendment updates the original EN 474-3:2006, ensuring alignment with the latest international standards and EU directives. The document supports the essential health and safety requirements laid out in the EU Machinery Directive 2006/42/EC and provides clear guidelines for manufacturers and operators to minimize risks during loader operation.

Key Topics

• Loader Safety Requirements
  This standard specifies mandatory safety features for loaders, including access systems, emergency egress provisions, and structural protections against falling objects (FOPS).

• Updated Normative References
  SIST EN 474-3:2007/kprA1:2008 replaces references to older standards with updated versions such as EN ISO 2867:2006, concerning access systems for earth-moving machinery.

• Falling Object Protective Structures (FOPS)
  For loaders with an operating mass of 700 kg or less, FOPS must meet the performance level defined in EN ISO 3449:2005 Level 1 when used in environments where falling objects pose a risk.

• Emergency Exits and Egress Openings
  The amendment revises the criteria around alternative egress openings, ensuring existing and new machinery complies with improved safety protocols.

• Compliance with EU Machinery Directive
  Annex ZB clarifies the relationship between this standard and EU Directive 2006/42/EC, highlighting the presumption of conformity when following the standard’s clauses.

Applications

This standard is essential for:

• Manufacturers of Earth-moving Machinery Loaders
  Ensuring design and production meet mandated safety criteria to reduce risk of accidents and improve operator protection.

• Construction and Excavation Operators
  Understanding operational safety features and maintenance requirements for loaders to maintain compliance and safeguard personnel.

• Inspection and Certification Bodies
  Using the standard as a benchmark for evaluating machinery safety and adherence to EU regulatory requirements.

• Safety Engineers and Compliance Officers
  Implementing risk management strategies based on the standard’s guidelines for machinery use in various earth-moving scenarios.

Practical Value

Adhering to SIST EN 474-3:2007/kprA1:2008 improves operational safety of loaders by defining clear, updated requirements on structural strength, operator egress, and protection against hazards. Compliance also facilitates smoother conformity assessments and market access within the European Economic Area. This standard is indispensable for reducing workplace incidents and meeting legal obligations related to machinery safety in construction and earth-moving industries.
