GB/T 5905.1-2023 Cranes - Inspection and text code - Part 1: General principle
1 Scope
This document specifies inspection and test items, test conditions and apparatuses, requirements and methods, records and reports for verifying crane performance (including working parameters and bearing capacity).
This document is applicable to the performance test of all types of cranes defined in GB/T 6974 (all parts), which are first put into use after their manufacture, renovation and the vital repair of their bearing structure or components.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 6974 (all parts) apply.
4 Inspection and test items
4.1 Inspection and test items for verifying crane performance, including but not limited to the following items:
a) visual inspection;
b) parameter measurement and performance verification;
c) load test;
d) noise test (if necessary).
4.2 For mass-produced cranes, the quantity of prototype cranes to be used for inspection and test shall be agreed between the manufacturer/supplier and the purchaser.
5 Test conditions and apparatuses
5.1 Test conditions
5.1.1 In order to carry out the test, the crane shall be equipped with working devices suitable for operation and shall have the conditions meeting the test requirements.
5.1.2 At least the following conditions shall be met during the test:
a) The test environment shall meet the working conditions of the crane.
b) The foundations and tracks shall have the conditions for crane operation. For example, the cranes running on track shall have the conditions for running on the track manufactured and laid according to the crane specifications; the cranes other than those running on track shall meet the requirements of the order contract.
c) The error of test load shall not exceed ±1%.
d) The inspection and test, when carried out outdoors, shall at least meet the following requirements:
1) the wind speed is not greater than 8.3m/s (30km/h), and the crane is not required to be in the most unfavorable position for wind action unless otherwise stipulated in the order contract.
2) the inspection and test shall not be conducted under extreme weather conditions such as heavy rain, fog, and blizzard that affect the test safety.
e) No obstacles affecting the normal operation of the crane are available on the test site, and warning signs shall be arranged to prevent irrelevant personnel or vehicles from
