What is ISO 12140‑2 about?
ISO 12140‑2 is the second part of the multi-series standard. ISO 12140‑2 is an International standard for quality assessment. ISO 12140‑2 deals with application safety, test methods and acceptance criteria for agricultural trailers and trailed equipment, specifically drawbar jacks.
ISO 12140‑2 specifies safety requirements, tests and acceptance criteria for the application of telescopic mechanical screw and nut-type drawbar jacks and hydraulic drawbar jacks intended to be fitted on the implement tongue of interchangeable towed machinery or jacks fitted with jack attachment mount.
ISO 12140‑2 applies to implement mounted jacks or jacks fitted with a jack attachment mount.
ISO 12140‑2 approved jacks are used specifically for supporting the hitch points of implements during storage, lifting and lowering of implement tongues to facilitate attaching to or disconnecting from an agricultural tractor and levelling of machinery for stationary use.
Who is ISO 12140‑2 for?
ISO 12140‑2 on application criteria for drawbar jacks is applicable to:
- Manufacturers of agricultural trailers and trailer equipment
- Quality control personnel
- Dealers and importers of agricultural trailers and trailer equipment
Why should you use ISO 12140‑2?
A trailer drawbar jack is a mechanism that is installed on the front of the trailer, it does the simple yet important job of lifting and lowering the front of your trailer. It facilitates connecting and disconnecting trailer from your tow vehicle which is impossible to do physically.
ISO 12140‑2 provides you with extensive guidance on safety requirements and test methods for drawbar jacks. ISO 12140‑2 informs you about the jack stand system application tests. These test methods recreate field conditions that the drawbar jack would endure in its operational life.
ISO 12140‑2 ensures that your drawbar jacks meet the minimum safety requirements.
