Overview
ISO 11525-1:2020 - Rough-terrain trucks - Safe use requirements - Part 1: Variable-reach trucks provides safety and safe-use requirements for non-slewing, variable-reach rough-terrain trucks (as defined in ISO 10896-1). The standard focuses on preventing personal injury, property damage and accidents by establishing clear criteria for application, inspection, maintenance, repair, training and safe operation of these machines. It is not applicable to lorry-mounted trucks; national or local rules may also apply.
Key topics and technical requirements
The standard covers practical, safety-focused topics including:
- Scope and definitions for variable-reach rough-terrain trucks and related terms (operator, user, competent person, maintenance, modification, stability).
- General principles for safe use: management responsibility, application selection, and ensuring operators are competent and fit for duty.
- Operator’s manual requirements: availability, interpretation and referral to the responsible entity when in doubt.
- Modifications and alterations: prohibition without manufacturer approval, or controlled procedures if the manufacturer is unavailable (design, testing, records, and labelling).
- Manufacturer’s bulletins: mandatory compliance where applicable.
- Operator qualifications and training: only competent, authorized operators trained per ISO 23676 may operate these trucks; familiarity with manuals, site rules and emergency procedures is required.
- Inspection and maintenance: planned inspection schedules, competent personnel, authorized areas for maintenance, preparation for repair (parking, disabling start, energy isolation, PPE), and performance checks (pre-operation inspections, control system tests).
- Operational safety rules: visual inspections, functional tests, safe travelling, picking/placing loads, using attachments, hazardous environment precautions and refuelling guidance.
Applications and who uses it
ISO 11525-1:2020 is intended for:
- Equipment users and owners who need to implement workplace safety programs for rough-terrain trucks.
- Operators to understand daily safe-use expectations and pre-operation checks.
- Maintenance teams and inspectors who perform scheduled inspections, repairs and performance checks.
- Manufacturers and responsible entities for producing manuals, addressing modifications and issuing safety bulletins.
- Safety managers, trainers and regulatory bodies who develop training, site rules and compliance programs.
Practical uses include developing operator training syllabi, defining inspection/maintenance regimes, authorizing modifications, and integrating safe-operating procedures on construction, mining and industrial sites where variable-reach rough-terrain trucks operate.
