Overview
ISO 2867:2011 - Earth-moving machinery - Access systems specifies ergonomic and safety criteria for access systems on earth‑moving machines (as defined in ISO 6165). The standard covers means of ingress/egress and movement to routine maintenance points - for example enclosure openings, platforms, guardrails, handrails and handholds, stairways, steps and ladders. Criteria are based on the 5th to 95th percentile operator dimensions (ISO 3411) and address key hazards: slip, trip and fall, unhealthy postures and excessive effort.
Key topics and requirements
- Scope of application: Access systems for machines parked per manufacturer instructions; selection guidance for fixed and portable systems used for repairs and maintenance.
- Access types: Primary/secondary access systems, retractable and powered retractable access systems, alternative exit paths.
- Design ergonomics: Use of inclined ladders where possible; design based on operator anthropometry (5th–95th percentile).
- Support and handhold rules: Encourage three‑point support for access >1 m; two‑point support acceptable for stairways, ramps, walkways and platforms.
- Slip resistance: All walking, climbing, stepping and crawling surfaces must be slip‑resistant (Annex A gives examples).
- Enclosure openings and passageways: Requirements for primary, alternative and maintenance openings to ensure safe passage.
- Stairways, steps and ladders: Definitions and geometric constraints (e.g., ramp ≤20°; stairway >20°–≤50°; ladder angle classifications).
- Safety features and aids: Guardrails, foot barriers, rest platforms, illumination for operator platforms >3 m, and recommendations for PFAS/PFRS for longer‑interval maintenance (see ISO 14567).
- Maintenance and documentation: Instructions in operator manuals for retractable systems, inspection, carrying items (e.g., stair/ramp or intermediate platforms 300 × 400 mm every 1.7 m), replacement and storage of removable parts.
- Durability: Design access parts for easy replacement when exposed to damage.
Applications and users
ISO 2867:2011 is intended for:
- Equipment manufacturers designing operator stations and maintenance access on excavators, loaders, bulldozers and other earth‑moving machinery.
- Safety engineers and ergonomic specialists developing machine access systems.
- Service and maintenance planners creating safe service procedures and external access solutions.
- Regulators and procurement teams specifying compliance and performance requirements.
Practical uses include specifying guardrail layouts, selecting ladder types, defining slip‑resistant surfaces, and writing operator manuals and maintenance procedures to reduce falls and musculoskeletal risk.
