Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard uses redrafted Law Amendment uses ISO 21873-1.2008 "Building construction machinery and equipment flow crusher 1

. Terminology and commercial specifications. "

This standard and ISO 21873-1.2008 as compared to the presence of technical differences, specific technical differences and their reasons are as follows.

--- 3.15.1 and 3.15.2 of the "machine quality machinemass" were changed to "quality of work operatingmass" and

"The quality of transport transportingmass", so with the ISO 21873-1 definitions of these two terms, as well as descriptions in parentheses

Our habits are consistent;

--- 3.16 Note deleted because the annotation expression is not clear, easy to cause confusion, GB/T 18577.1-2008/ISO 6746-1.

2003 "Defining the size of earth-moving machinery and symbols - Part 1. Host" in Appendix A of the ground clearance is also given the same

Meaning, but without any comment;

--- 4.3d) in the "V-belt" to "belt", pointed out that since only "V-belt" limit the use of other belt;

--- 5.2.1d) "net power" to "power rating" because domestic and international definition of the rated power is clear and unified, while the net

No unified definition of power or is not defined;

--- 5.2.9d) "trailer wheelbase" added "(kingpins to the horizontal distance from the center axis of the group)," the instructions, otherwise the trailer axle

Distance is not clear, explanation of the increase comes from the GB/T 3730.3-1992 "vehicles and trailers terms and definitions vehicle size"

3.4.2, 5.2.9 of this standard on the "axle load" is also "on-axis group Center" instructions;

And "axle load" belongs Relations "kingpins design height" and "kingpins load" --- canceled 5.2.9f), whereas the "kingpin load

Dutch "and" axle load "are listed separately, because there is no affiliation between them.

This standard also made the following editorial changes.

--- Deletion of ISO 21873-1.2008 Foreword and Introduction of ISO .

The standard proposed by China Machinery Industry Federation.

This standard by the national construction machinery and construction equipment Standardization Technical Committee (SAC/TC328) centralized.
