In the process of hoisting machinery testing inspection, we found that a lot of manufacturing installation dept and end users blind to operate the overload test, when they don’t know well about the loading test processing, the result is often not ideal, and will also bring damage to the structure of the crane, lead to new potential accidents, bring economic disputes. In this paper, the conditions and procedures of load test and judgment are discussed so that cause the attention of the relevant dept.
Some condition missing when make a loading test , easily lead to accidents.
1. Products quality without verified, especially the main stress part weld line without inspection, crane without a quality certificate .
2. Crane without finishing mounted and verify by installation director before handover.
3. Safety device is not complete, unqualified crane.
4. Lack of full oil lubrication, prone to gear abrasion damage, failure, and cause an accident.
