ISO 13031
Safety standard for quick couplers on earth-moving machinery, specifying requirements that guard against accidental attachment release.
ISO 13031:2016/Amd 1:2025 specifies safety requirements and performance tests for quick couplers used on earth-moving machines. Its aim is to prevent attachment drop incidents.
Safety features it deals with: 1. Front Lock: Separate locking system at front of attachment 2. Safety Springs: Maintain lock position if hydraulic pressure lost 3. Visual Indicator: Shows locked/unlocked status from operator position 4. Connection Test: Procedure to verify full engagement before lifting
Testing requirements:
- Static strength tests
- Dynamic fatigue tests
- Lock mechanism reliability
- Environmental testing (temperature, dust)
Compliance importance:
- Contractors may ask for ISO 13031 conformity before a coupler goes on site
- Insurance coverage may depend on compliant equipment
Sieruta quick couplers are designed to ISO 13031. Each coupler family page lists the locking features that family has.
