Earth-moving machinery - Volumetric ratings for hoe-type and grab-type buckets of hydraulic excavators and backhoe loaders

ISO 7451:2007 specifies a method for estimating the volume of materials which a hoe-type or grab-type bucket of a hydraulic excavator or backhoe loader can normally contain. The volume assessments are based on the internal dimensions of the bucket and on the representative volumes at the top of the bucket. The method employs the technique of dividing the complex shape of the material in the bucket into simple geometric shapes. This method of assessment is intended to provide a conventional means of comparing bucket capacities. It is not intended to be used to define true capacities.

Le présent document s'adresse aussi bien aux concepteurs qu'aux utilisateurs des godets rétro montés sur pelles ou sur chargeuses-pelleteuses, car il permet une évaluation rapide de la capacité des godets. Une méthode plus complète figure dans la norme NF E 58-077.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
