Reasons for the disqualification of lifting equipment in Zhongyuan Heavy Industry

During the inspection of lifting machinery and other equipment, Henan Zhongyuan Heavy Industry Equipment Co., Ltd. strictly follows inspection standards, but sometimes discovers non-compliant equipment. There are many influencing factors. Through long-term observation and statistics, the main reasons are found in the following aspects:

During Henan Zhongyuan Heavy Industry Equipment Co., Ltd.'s inspection of lifting machinery, discrepancies often exist between product markings and regulatory requirements. According to lifting machinery regulations, equipment should have graded working levels, so incomplete documentation is a common cause of non-compliance. Secondly, in various parts of lifting machinery, some installation details are often overlooked by designers, such as neglecting to install main circuit contactors. This fails to leave sufficient operational space for installers, leading to easily adhered contact points in the operating system, which adversely affects the machinery's operation.

Additionally, Henan Zhongyuan Heavy Industry Equipment Co., Ltd. considers unreasonable design of lifting machinery as another major factor causing inspection failures. During production, certain components may sometimes be missing. According to lifting machinery safety regulations, emergency stop switches often replace the equipment's tonnage switches during startup. Over time, emergency switches wear out, reducing the equipment's responsiveness in emergencies and potentially causing accidents. Therefore, the equipment must have pressure loss protection. Moreover, neglecting grounding wire installation can also lead to non-compliant equipment detection and may endanger operators.
