GB/T 5905.1-2023Cranes—Inspection and test code—Part 1:General principle (English PDF)

Foreword

This document was drafted in accordance with the rules provided in GB/T 1.1-2020 Directives for Standardization - Part 1: Rules for the Structure and Drafting of Standardizing Documents.

GB/T 5905 Cranes - Test Code and Procedures, GB/T 21457 Cranes and Related Equipment - Accuracy Requirements for Measuring Parameters during Testing, GB/T 22414 Cranes - Measurement of Velocity and Time Parameters, GB/T 22415 Cranes - Requirements for Test Loads and GB/T 30025 Cranes - Measurement of the Mass of a Crane and Its Components jointly constitute the national standard system for general test methods for supporting cranes.

This document is Part 1 of GB/T 5905 Cranes - Inspection and Test Code. GB/T 5905 has issued the following part.

---Part 1: General Principle.

This document serves as a replacement of GB/T 5905-2011 Cranes - Test Code and Procedures.

In comparison with GB/T 5905-2011, apart from structural adjustments and editorial modifications, the main technical changes are as follows.

a) Terms and definitions are added (see Chapter 3);

b) Noise test requirements when necessary are added [see 4.1 d)];

c) The test conditions are modified, including the addition of test load requirements, extreme environmental conditions and instrument requirements, etc. (see Chapter 5; Chapter 5 of Version 2011);

d) The visual inspection requirements are modified, including the addition of visual inspection items, such as. pneumatic equipment, safety signs and hazard illustrations, etc. (see 6.2; 4.2 of Version 2011);

e) The name of qualification test and inspection is modified into "parameter measurements and performance verification"; parameter measurements, such as. load-lowering height, track tolerance, span, track gauge, base distance, amplitude, cantilever effective reach and safety distance, are added; important weld quality inspection and its non-destructive testing method when necessary are added (see 6.3;

4.1 of Version 2011);

f) No-load test and rated load test are added (see 6.4.2 and 6.4.3);

g) The static load test method is modified, including the deletion of the provision that "if the crane specifications permit, a static load test of the joint action of the hoisting mechanism shall also be performed" (see 6.4.4; 4.3.2 of Version 2011);

h) The dynamic load test method is modified (see 6.4.5; 4.3.3 of Version 2011);

i) The stability test method is modified (see 6.4.6; 4.3.4 of Version 2011);

j) The noise test method is added (see 6.5);

k) The requirements for the test record are added (see 7.1).
