This standard provides a uniform method to calculate and a test procedure to validate hydraulic excavator lift capacity. It establishes definitions and specifies machine conditions for calculations in Section 1 and identifies the validating test procedure in Section 2.

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. Bucket teeth, tooth adapters, as well as other similar local discontinuities are ignored. a. Interpretation of irregular shaped cutting edges is identified in 4.4. b. Interpretation of irregular shaped side sheets is identified in 4.5.

This SAE Standard provides uniform definitions of specification terms peculiar to loaders as defined in SAE J1057. The specifications must be qualified by stating the track shoe type, width or the tire type, size, ply, and specified inflation pressure; the model number or type of bucket disregarding teeth; and the type and amount of counterweight and/or ballast, if any, with which the machine is equipped. Paragraphs 4.1 to 4.16 are further defined by Figures 1 to 4. The figures 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 (July, 1973)?Identification Terminology of Earthmoving Machines for machine type.

This SAE Standard establishes the definition of a normal all day rated operating load for loaders as defined in SAE J1057. This SAE Standard applies to wheel and crawler loaders taking only hydraulic lift capacity and tipping capacity into consideration. It is recognized that specific operating conditions may allow larger, or require smaller loads than the rated operating load. Some conditions could require more careful or restricted operation with the rated operating load. This standard is not to be construed as setting up test procedures or conditions.

This SAE Recommended Practice applies to wheel and crawler loaders when equipped with log or material handling forks without vertical masts, taking only hydraulic lift capacity and operating stability into consideration. It is recognized that specific operating conditions may allow larger, or require smaller loads than the rated operating load. Some conditions would require more careful or restricted operation with the rated operating load. This practice is not to be construed as setting up test procedures or conditions.

This SAE Standard provides a uniform method for determining rated and struck capacity for buckets used on excavators, mini-excavators, and backhoes as defined in SAE J1057 and equipped with hoe attachment. Calculations are based on the inside physical dimensions of the bucket only, without use of optional side cutters, spill guards, teeth, or other accessories and without regard to bucket action provided by any specific machine. This document does not cover shovel, clam, or dragline buckets described in SAE J67 or loaders buckets described in SAE J742.

This recommended practice applies to hydraulic excavators as defined in SAE Standard J1057.

To be used on cutting edges and end bits in conjunction with No. 3 head plow bolts (Ref. ANSI B18.9) typically used on off-road self-propelled work machines as described in SAE J1116. Cutting edges are further defined in SAE J737, J739 and J1304. End bits are further defined in SAE J63. 1 When section thickness exceeds A in drawing 1 (Figure 2) (countersunk one side) or B in drawing 4 (countersunk both sides), use counterbore with diameter D, as shown in cross section drawings 2, 5 and 6, or extended countersink C, as shown in cross section drawings 3 and 7. 2 The inscribed circle of the square holes shall be concentric with countersink or counterbore within 0.03 in (0.8 mm).
