GB/T 18577.2-2008Earth-moving machinery -- Definitions of dimensions and codes -- Part 2: Equipment and attachments (English PDF)

Foreword

GB/T 18577 "moving machinery size and symbol definitions" is divided into two parts.

--- Part 1. Host;

--- Part 2. Equipment and fixtures.

This section GB/T 218 577 Part of this part identical with ISO 6746-2:2003 "moving machinery size and symbols Definitions - Part 2. Equipment and fixtures "(in English).

This section is equivalent translation ISO 6746-2:2003.

For ease of use, this section made the following editorial changes.

--- "This International Standard" be replaced by "this section";

--- Deleted international standards foreword;

--- To ISO 6746-2:2003 international standard referenced with the international standard has been adopted as the standard instead of the corresponding country.

This Part replaces GB/T 18577.2-2001 "moving machinery - Definitions of dimensions and symbols Part 2. Equipment." this section compared with the GB/T 18577.2-2001, the main changes are as follows.

--- Standard name from "earth-moving machinery - Definitions of dimensions and symbols Part 2. Equipment" to "earth-moving machinery and character size Defined number - Part 2. Equipment and fixtures ";

--- Standard English name was modified accordingly;

--- Original 3.1 "three-dimensional coordinate system" and the contents of Appendix A merger is 3.1 "three-dimensional coordinate system", and the content of the standard will be Modified accordingly;

--- Adjust and modify the contents of the appendix.

This section of the Appendix A, Appendix B, Appendix C, Appendix D and Appendix E are normative appendix.

This part is proposed by China Machinery Industry Federation.

This part of the National earthmoving machinery Standardization Technical Committee (SAC/TC334) centralized.

This section is drafted. Tianjin Construction Machinery Research Institute.

1 Scope

This section GB/T 18577 specifies the definition of the size of the symbol of earth-moving machinery and work equipment attachments and provides for the use in size defined coordinate system, coding system terminology standards and commercial specifications in the corresponding size.

This section applies to GB/T 8498 basic types of earth-moving machinery and work equipment and fixtures defined.

3 Terms and Definitions

GB/T 8498 and established the following terms and definitions apply GB/T 18577 in this section.

Moving machinery used to define the size of the three-dimensional coordinate system (Figure 1).

3.1.1

Vertical plane through the longitudinal center line of the machine.

3.1.2

Any of a vertical plane perpendicular to the Y plane.

3.1.3

Either the horizontal plane X and Y plane orthogonal to the plane.

3.1.4

Above the front plane of the zero X, Y plane to the right of zero and zero Z plane are positive directions.

Note 1. The intersection of the X, Y, Z axis (zero plane) should be located on a well-defined reference point (seat index point; the engine crankshaft centerline; bulldozer driver Rear axle or wheel center line; the whole measure of the horizon).

Note 2. If only represents a member (the engine, the seat), from the X, Y, Z-axis (zero plane) from the intersection of the axis relative to the orientation of the machine components should be in Normal position (first cylinder of the engine facing the front of the machine; the seat facing forward) is determined as the positive direction.

Note 3. If you represent a machine or a work unit, you should indicate the machine is traveling from right to left orientation.
