Capacity Rating--Loader Bucket J742_198502

The purpose of this standard is to provide a uniform method for determining the SAE struck capacity and rated capacity. The volume calculations used results in a realistically conservative heaped volume. The calculations are based on the inside physical dimensions of the bucket only without regard to bucket action provided by any particular machine. for rating purposes, a nominal heaped load with a 2:1 angle of repose is to be used with bucket orientation dictated by the strike plane defined in paragraph 3.1. This in no way implies that the loader linkage must carry the bucket oriented in this attitude, or that all materials will naturally have a 2:1 angle of repose. This standard applies to buckets of loaders (as defined by SAE J1057a, Identification Terminology of Earthmoving Machines). This method applies primarily to buckets having parallel sides and a cutting edge parallel to the top edge of the top edge of the back sheet. Moderately clipped back sheet corners will introduce no appreciable errors. bucke tteeth, tooth adapters, as well as other similar local discontinuities are ignored. (a) Interpretation of irregular shaped cutting edges is identified in paragraph 4.4. (b) Interpretation of irregular shaped side sheets is identified in paragraph 4.5.
