The Causes of Corrosion in Overhead Cranes by Zhongyuan Heavy Industry

Through long-term experience in the crane manufacturing industry, Henan Zhongyuan Heavy Equipment Co., Ltd. has found that equipment corrosion poses significant hazards to cranes. It not only causes a certain degree of damage to the equipment, affecting the operational performance of the crane, but may also lead to serious accidents. Therefore, anti-corrosion measures are crucial. So, what are the causes of corrosion in steel structures of cranes, and what patterns can be followed?

Based on the requirements and standards of crane inspection institutions, Henan Zhongyuan Heavy Equipment Co., Ltd. has summarized the following causes and precautions.

The corrosion rate of crane steel structures varies in the atmosphere, starting relatively fast and gradually slowing over time. Therefore, the initial protective painting and coating work for new equipment must be done thoroughly to avoid omissions or deficiencies. Additionally, Henan Zhongyuan Heavy Equipment Co., Ltd. has found that the degree of atmospheric corrosion on steel structures differs significantly across various working environments. Among these, coastal and heavily polluted areas experience particularly severe corrosion. Of course, due to climatic factors, corrosion conditions can vary even within the same working area. Without enhanced protection during the rainy season, equipment will suffer severe corrosion.

Through experiments, Henan Zhongyuan Heavy Equipment Co., Ltd. concluded that the corrosion rate of crane steel structures with paint or electroplated layers is about five times slower than those without protective coatings. Outdoor operations result in corrosion rates nearly four times faster than indoor operations. Understanding these patterns allows for effective prevention of corrosion issues.

Of course, users can also summarize more suitable methods based on their own experience during operation. Henan Zhongyuan Heavy Equipment Co., Ltd. has continuously explored and innovated in the production and manufacturing of crane machinery and equipment, ensuring reliable product quality and safety.
