Rated Operating Load for Loaders
2013-01-02
CURRENT
J818_201301
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.

Lift Capacity Calculation and Test Procedure-Pipelayer and Sideboom
2011-12-08
CURRENT
J743_201112
This SAE Standard describes a method to calculate and a test procedure to validate rated lift capacity as presented in commercial literature for pipelayers and tractors or loaders (wheel or crawler), equipped with a hydraulic or mechanically operated sideboom. Rated lift capacity considers hoist mechanism limits, tipping loads, and rope factor. After the lift capacity is validated by testing, a reduction factor is applied to establish the rated lift capacity for the specific pipelayer or sideboom configuration.

Nomenclature - Rollers and Compactors

CURRENT
J1017_201110
This SAE Standard provides names of major components peculiar to rollers and compactors. Illustrations of components are not intended to be exactly descriptive of any particular machine. NOTE: Rollers and compactors will be defined in a section added to SAE J1057a.

Cutting Edge - Cross Sections Loader Straight with Bolt Holes
2011-10-25
CURRENT
J1304_201110
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. NOTE—For some heavy-duty applications, cross sections with larger blunts, greater bevel angles, and larger bolt holes may be required.

Countersunk Square Holes for Cutting Edges and End Bits
2011-10-25
CURRENT
J740_201110
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).

Hole spacing is defined for dozers and scrapers in J737 and graders in J739. Hole conformation is defined in J740.

Earthmoving Machinery-Coupling of Attachments to Skid Steer Loaders
2008-05-01
CURRENT
J2513_200805
This SAE Standard sets forth standard dimension requirements for the loader attachment bracket and attachment interface to allow interchangeability of attachments on skid steer loaders whose operating mass (see SAE J/ISO 6165) is 4,500 kg or less. Narrow skid steer loaders may have a width that does not allow compliance with this standard. The design of the loader attachment bracket locking system is not restricted by this standard and is left to the discretion of the manufacturer. The purpose of this document is to provide dimensions to standardize the coupling interface between skid steer loaders and their attachments that are manufactured worldwide.

Hole Spacing for Scraper and Dozer Cutting Edges

CURRENT
J737_200708
This standard is intended for cutting edge sections used on: a. Tractor-scrapers as described in SAE J1057 and J728 b. Dozers as described in SAE J729. These cutting edges are further defined in SAE J738 for cross section and SAE J740 and J1580 for hole conformation. (Note: Some inch dimentions in this standard are not equivalent to the corresponding millimeter figures because values which are widely used have been adapted. This standard specifies hole placement along with length and width of the cutting edge.

Specification Definitions—Loaders
2007-04-30
HISTORICAL
J732_200704
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.
