GB/T 13331-2014Earth-moving machinery -- Hydraulic excavators -- Lift capacity (English PDF)

Foreword

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

This standard replaces GB/T 13331-2005 "moving machinery - Hydraulic excavator from the weight." This standard and GB/T 13331- Compared to 2005, in addition to editorial changes outside the main technical changes are as follows.

--- Add and remove some of the normative references;

--- Modify a number of terms and definitions (see 3.2, 3.3 and 311 in 2005, version 3.2 and 3.9.);

--- Increasing the number of terms and definitions (see 3.11.3,3.14,3.15,3.16,3.17 and 3.18);

--- Modify the part of the calculation method (see 41, 2005 version 4.1.);

--- Removed some test requirements (see 2005 5.3.6);

--- Modify the part of the test requirements (see 5.3.7,5.3.9 and 54, 2005 edition of the 5.4, 5.5.);

--- Modifications and additions about the graphics [Figure 2, Figure 3a) and Figure 3b), 2005 edition of Figures 2 and 3];

This standard uses the translation method identical with ISO 10567:2007 "moving machinery - Hydraulic excavator from the weight" (in English).

Correspondence between the consistency of the standards of international documents and normative references of the following documents.
