Cutting Edge - Optional Cross-Sections and Dimensions Loader Straight
Description / Abstract:
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.
Cutting Edges without Holes—The dimensions, for cutting edges used on buckets for loaders defined in SAE J1057, are appropriate to rolled, cast, forged, flame cut, and machined sections. This recommended practice applies only to straight cutting edges, which are those whose leading edge and rear edge are parallel and, thus, are of constant cross section. Cutting edge cross-section thicknesses below 20 mm and above 35 mm are not changed from SAE J1303 and are not included.
Cutting Edges with Bolt Holes—The dimensions, for cutting edges used on buckets for loaders defined in SAE J1057, are appropriate to rolled and machined sections only. This recommended practice applies only to straight cutting edges, which are those whose leading edge and rear edge are parallel and, thus, are of constant cross section. Cutting edge cross-section thicknesses below 20 mm are not changed from SAE J1304 and are not included. Maximum thickness has been increased to 45 mm. Selected cross-section widths are a minimum required to accommodate bolt-on tooth adaptors. Welded-on teeth are used on thicker bucket cutting edges.
