ISO 11525-2:2020

Overview

ISO 11525-2:2020 - "Rough-terrain trucks - Safe use requirements - Part 2: Slewing variable-reach trucks" specifies safe-use requirements for slewing variable-reach rough-terrain trucks (commonly called rotating telehandlers or multi-purpose rotating handlers). The standard focuses on application, inspection, maintenance, repair, operator qualifications and safe operation to prevent personal injury, property damage and accidents. It is the second edition (2020) and complements ISO 10896-2 (equipment definition and safety verification) and other parts of the ISO 11525 series.

Key topics and technical requirements

• Scope and applicability
  • Applies to slewing variable-reach rough-terrain trucks only; not applicable to lorry‑mounted trucks or mobile cranes.
  • National/local regulations may also apply.
• Operator responsibilities and training
  • Only competent, authorized operators may use the truck.
  • Operators must be familiar with the manufacturer’s operator’s manual and site‑specific rules and emergency procedures.
  • Training requirements are addressed alongside ISO 23676.
• Inspection, maintenance and repair
  • Requires planned systems for scheduled inspection, lubrication, maintenance and adjustment.
  • Inspections and maintenance must be performed by competent personnel in authorized areas with safe clearances.
  • Preparation steps before inspection/repair include parking on firm level ground, isolating power, preventing unintentional movement and eliminating stored-energy hazards.
• Performance checks and pre‑operation testing
  • Pre-operation inspection and recorded checks are required; functional testing of steering, brakes, load-handling and safety devices must follow manufacturer instructions.
• Modification, documentation and manufacturer interaction
  • No modification affecting capacity, stability or safety without written approval from the original manufacturer or successor.
  • If manufacturer is unavailable, competent-person design/testing must follow ISO 10896-2 and permanent records/labels are required.
• Other safety controls
  • Requirements for operator manuals to be available, compliance with manufacturer bulletins, handling of hazardous environments and refuelling provisions (added/clarified in this edition).

Practical applications and users

• Intended users:
  • Fleet managers, site safety officers, inspection and maintenance teams, equipment owners, rental companies and trainers.
  • Manufacturers and OEM service organizations for compliance guidance.
• Typical uses:
  • Safe operation and maintenance guidance for rotating telehandlers used in construction, agriculture, utilities, and industrial sites where variable reach and slewing capability reduce repositioning needs.
• Benefits:
  • Reduces accident risk, standardizes inspection/maintenance procedures, clarifies operator competency and documents requirements for safe modifications.
