GB/T 25196-2018Cranes -- Monitoring for crane design working period (English PDF)

Foreword

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

This standard replaces GB/T 25196.1-2010 "Crane Status Monitoring Part 1. General", and GB/T 25196.1-2010

In comparison, the main technical changes are as follows.

---Modified standard name (see cover);

--- Revised the scope of the content (see Chapter 1, Chapter 1 of the.2010 edition);

---Modified terms and definitions (see Chapter 3, Chapter 3 of the.2010 edition);

--- Increased crane work records, design work cycle assessment (see Chapters 4 and 5);

--- Revised the content of the special assessment (see Chapter 6, Chapters 4, 6, 7, and 9 of.2010);

--- Increased the content of crane overhaul (see Chapter 7);

--- Increased DWP calculations for cranes and hoisting mechanisms (see Appendix A, Appendix B);

--- Removed the contents of the evaluation criteria for the series of lifting hoists in the original standard (see Appendix A of the.2010 edition).

This standard uses the translation method equivalent to ISO 12482.2014 "Monitoring of crane design work cycle".

1 Scope

This standard specifies the method for monitoring the actual working conditions of the crane during long-term use, and specifies and grading (related design standards).

See ISO 4301-1) for the initial design work tasks to be compared. The closer to the design life limit, the possibility of danger

The greater the sex. The crane usage monitoring method specified in this standard is used to predict whether the crane is close to the design life limit and pay attention to the crane off

Special inspection of the key parts.

This standard is mainly used to adjust or change the inspection requirements specified in ISO 9927-1.

This standard applies to cranes with a permanent construction throughout their life.

This standard does not apply to mobile and tower cranes, except for permanently installed tower cranes.

Note. The methods specified in this standard are used by standards or procedures in addition to ISO 4301-1, which can be classified.
