Inspection Requirements and Frequency
Factory inspections shall be conducted unit by unit by the quality inspection department at the manufacturer’s facility. Equipment that passes inspection shall be accompanied by a detailed inspection report and a certificate of conformity. Type testing shall be conducted when a new product enters production for the first time, when production is transferred to a different facility, or when major structural changes are made. The periodic inspection interval for in-service equipment shall be determined based on the duty class and operating environment, and generally shall not exceed 12 months.
| Project | Technical Requirements | Note |
|---|---|---|
| 弹簧检查 | 张力衰减/疲劳 | 季度+张力不足调整 |
| 碳刷 | 磨损≤原厚50% | 月度+接触面平整 |
| Cable | 外皮破损/受力 | Monthly + Replace as Soon as You Notice a Problem |
| 滑环 | 接触电阻测量 | 年度+≤10mΩ |
Safety Operation and Management Requirements
The standard places particular emphasis on the importance of operator qualifications and training, requiring that all operators undergo specialized training and obtain the appropriate qualifications before being allowed to operate the equipment. Organizations using the equipment should establish a comprehensive equipment record-keeping system to document in detail the entire process of installation, use, maintenance, and inspection.
