This part of ISO 14397 specifies the means for determining the rated operating capacity of wheeled or crawler loaders or of the loader portion of backhoe loaders, having buckets and material handling forks, as defined in ISO 6165. It gives standard methods for the calculation and test verification of the tipping load (mass). It is applicable only to the use of buckets and forks on loaders. NOTE Certain attachments can exceed the normal operating capacity and will require restricted machine operating conditions, such as reduced machine speed or limited lifting height. Refer to the attachment manufacturer’s instructions for the intended use of the attachment.
