GB/T 25625-2017Earth-moving machinery -- Trainer seat -- Deflection limiting volume, space envelope and performance requirements (English PDF)

Foreword

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

This standard replaces GB/T 25625-2010 "Earth-moving machinery dump truck coach seat/environment space." This standard and GB/T 25625-2010 compared to editorial changes in addition to the main technical changes are as follows.

--- Modify the standard name;

--- Modify the scope of the standard (see Chapter 1, 2010 Edition Chapter 1);

--- Modify, increase the normative references (see Chapter 2, 2010 edition Chapter 2);

--- Modify, add terms and definitions (see Chapter 3, 2010 edition Chapter 3);

--- Modify "Seat Size" "Coach Seating Position" "Coach Size/Adjustment/Suspension of Environmental Space" "Material" "Handrail" "Storage Requirements for Survival and Constraint Systems (see 4.1, 4.2, 4.3, 4.7, 4.8, 4.9 and 4.10, Chapter 4 of the 2010 Edition);

--- Added "Trainer's seat FOPS or roof guard requirements" "trainer seat ROPS requirements" and "trainer seat ROPS/FOPS or top guard label "requirements (see 4.4, 4.5 and 4.6);

--- Increases the size of coach DLV and coaches DLV acceptance criteria (see Appendix A and Appendix B);

--- Added references (see references).

This standard uses the translation method identical with ISO 13459:2012 "Earth-moving machinery trainer seat deflection limit, environmental space and Performance requirements. " the normative references to this standard in international documents corresponding to the consistency of our documents are as follows.

This standard is proposed by the China Machinery Industry Federation.

This standard by the National Earth Machinery Standardization Technical Committee (SAC/TC334) centralized.

1 Scope

This standard specifies the amount of flexing limit of the trainer's seat, environmental space and performance requirements and dimensions for earthwork defined by ISO 6165 Laboratory evaluation of mechanical protection structures.

The impact of vibration on short-term or temporary seats is not considered as a significant hazard and therefore this standard does not consider the effects of vibration.
