This standard applies only to straight, angling, semi-U, and U-blades for crawler and wheel tractors. It applies to angling blades only in the straight (not angled) position.
This SAE Standard specifies a procedure for approximating the volume of a typical material carried in the bowl of an elevating scraper as defined in SAE J728 and SAE J1057. The volumes are based on the inside dimensions of the bowl and a representative volume on top of the bowl. This rating method is intended to provide a consistent means of comparing capacities; it is not intended to define actual capacities that might be observed in any specific application.
This SAE Standard specifies a procedure for approximating the volume of typical materials contained in the bowl of Open Bowl scrapers as defined in SAE J728 and SAE J1057. The volumes are based on the inside dimensions of the bowl and representative volumes on top of the bowl. This rating method is intended to provide a consistent means of comparing capacities; it is not intended to define actual capacities that might be observed in any specific application.
This SAE Standard provides names of major components peculiar to tractors used with scrapers and dumpers. (See Figures 1 to 3.) Reference SAE J1057. Illustrations of components are not intended to be exactly descriptive of any particular machine.
This SAE Standard provides names of major components peculiar to dumpers as defined in SAE J1057 (see Figure 1). Illustrations of components are not intended to be exactly descriptive of any particular machine. For component nomenclature for dumper trailers, refer to SAE J734.
This SAE Standard provides names of major components peculiar to graders as defined in SAE J1057 (See Figure 1). Illustrations of components are not intended to be exactly descriptive of any particular machine.
This standard includes names of major components and parts peculiar to this type machine. The illustrations are descriptive of the principles and are not intended to include all existing commercial machines. [Refer to SAE J1057 JUL73)—Identification Terminology of Earthmoving Machines for machine type.]
This SAE Standard provides names of major components peculiar to the scraper portion of tractor-scrapers. Reference SAE J1057. Illustrations of components are not intended to be exactly descriptive of any particular machine.
For cutting edges used on buckets for loaders defined in SAE J1057a. The dimensions are applicable to rolled, cast, forged, flame cut, and machined cutting edge sections. Straight cutting edges are defined as those whose leading edge and rear edge are parallel and, thus, are of constant cross section. For "straight cutting edge sections with bolt holes," see SAE J1304 FEB85.
For cutting edges used on buckets for loaders defined in SAE J1057a. The dimensions are applicable to rolled and machined sections only. Cutting edge cross section thickness is limited to a maximum of 35 mm. Bolt-on tooth adapters are rarely used on loader buckets with cutting edge thicknesses in excess of 35 mm. This recommended practice applies only to straight cutting edges defined as those whose leading edge and rear edge are parallel and thus are of constant cross section. Overall cross sections to which bolt holes were added as indicated by this recommended practice were selected from those indicated per "Cutting Edge—Cross Sections Loader Straight," SAE J1303 FEB85. Selection was based on minimum section width requirements to accommodate bolt-on tooth adapters.
This SAE Standard is intended for curved cutting edge sections used on graders as defined in SAE J870 and J1057. (See Figure 1 and Table 1.) Hole conformation is further defined in SAE J740 and J1580.
This standard is for cutting edge sections typically used in earthmoving machinery defined in SAE J1507: a Tractor - Scrapers as defined in SAE J728. b Dozers as described in SAE J729 and J173. c Loaders as described in SAE J731. d Graders as described in SAE J870. Hole spacing is defined for dozers and scrapers in J737 and graders in J739. Hole conformation is defined in J740.
The purpose of this SAE Recommended Practice is to specify dimensions for loader straight cutting edge cross sections without holes and with bolt holes for mounting bolt-on teeth and tooth adaptors on loader buckets described by SAE J731. This recommended practice is intended to supplement SAE J1303 and SAE J1304 with cross sections for heavier duty applications, by identifying larger blunts, greater bevel angles, larger bolt holes, and greater bolt spacing.
