Rough-terrain trucks — User requirements — Part 4: Additional requirements for variable-reach trucks handling freely suspended loads
ISO 11525-4:2016, when used in conjunction with ISO 11525‑1 or ISO 11525‑2, defines specific user requirements relating to the use of non-slewing and slewing variable-reach trucks operating with freely suspended loads. When provisions of this part of ISO 11525 are different from those which are stated in ISO 11525‑1 or ISO 11525‑2, the provisions of this part of ISO 11525 take precedence over the provisions of ISO 11525‑1 or ISO 11525‑2. It is intended to achieve the following: a) prevention of personal injuries, property damage and accidents; b) establishment of criteria for inspection, maintenance, operation and training. NOTE National or local requirements can apply, whichever could be more stringent. General user requirements for non-slewing variable-reach trucks are given in ISO 11525‑1. General user requirements for slewing variable-reach trucks are given in ISO 11525‑2. ISO 11525-4:2016 is not applicable to flexible intermediate bulk containers as defined in ISO 21898.

Overview
ISO 11525-4:2016 - "Rough-terrain trucks - User requirements - Part 4: Additional requirements for variable-reach trucks handling freely suspended loads" provides specific user-focused safety, training, inspection and operational requirements for slewing and non‑slewing variable‑reach rough‑terrain trucks when they handle freely suspended loads. Used alongside ISO 11525‑1 or ISO 11525‑2, this part takes precedence where its provisions differ. It aims to prevent personal injury and property damage and to establish clear criteria for operation, maintenance and training. Note: ISO 11525‑4:2016 is not applicable to flexible intermediate bulk containers (see ISO 21898).
Key topics and technical requirements
- Scope & precedence: Supplements ISO 11525‑1/‑2; where conflicts exist, Part 4 prevails for freely suspended loads.
- Operator documentation: Operators must have access to the manufacturer’s operator’s manual and safety bulletins.
- Training & qualifications:
- Mandatory additional training on handling freely suspended loads (stability effects, tethering, boom positioning, signalling and rigging).
- Practical testing on pick‑up and placement; retraining and record keeping required.
- Pre‑lift checks:
- Verify total load weight including rigging and load centre.
- Confirm ground/surface capacity and frame levelling per manufacturer limits.
- Use approved lifting points and do not suspend loads from forks unless manufacturer‑approved.
- Operational controls:
- Use tether/tag lines and trained personnel when travelling with suspended loads.
- Employ a qualified signal person if visibility is obstructed; follow ISO 16715 hand‑signal guidance.
- Keep loads low, vertical lifts only, avoid dragging or horizontal pulling.
- Never lift personnel on suspended loads; observe wind and fall‑zone restrictions.
- Attachments & equipment:
- Ensure attachments are secured and locking devices engaged.
- Reset rotating fork carriages to neutral before lifting; verify attachment stability under load and vibration.
Practical applications
ISO 11525‑4:2016 is used to manage risks whenever variable‑reach rough‑terrain trucks handle suspended loads. Typical use cases include:
- construction sites, civil engineering and infrastructure
- mining and quarry operations
- oil & gas and utilities maintenance
- heavy equipment yards, ports and logistics hubs It provides actionable guidance for safe lift planning, operator competency, site controls and maintenance practices.
Who should use this standard
- Truck operators and trainers
- Fleet managers and safety officers
- Equipment manufacturers and dealers
- Site supervisors, riggers/slingers and occupational safety regulators
