　　Semi-enclosed hook group is a common lifting equipment, but some common problems may be encountered during use. The following will discuss the common problems and solutions of semi-closed hook groups.

　　First, one of the common problems is the insufficient load-bearing capacity of the hook group. This may be caused by defects in the design or manufacturing process, or by long-term use or incorrect operation. Solutions to this problem include evaluating and verifying the load-bearing capacity of the hook set and performing load testing before use to ensure that it meets safety standards. If problems are found, damaged parts should be replaced or repaired in time.

　　The second common problem is the increase in the operating resistance of the hook group caused by poor lubrication. Continuous poor lubrication can increase friction, causing the hook set to run poorly and may even lead to equipment failure. The solution to this problem is to check the lubrication system regularly to ensure the adequacy and quality of the lubricant oil. At the same time, pay attention to cleaning the working surface of the hook set to avoid accumulation of dust and debris.

　　The third common problem is electrical system failure. Semi-enclosed hook group is usually equipped with an electrical control system. If the electrical system fails, it will affect the normal operation of the hook group. The solution to this problem includes regularly checking the connections and lines of the electrical system to ensure that it is stable and reliable. At the same time, operators need to receive relevant training to understand the basics of electrical systems and how to deal with common failures.

　　Also, one of the common problems is the lack of safety measures. The operation of the semi-enclosed hook set may involve dangerous environments such as high altitude operations, so the lack of safety measures may lead to serious accidents. The solution to this problem is to establish strict safety operating procedures and provide necessary personal protective equipment. Operators need to be trained to understand safety operation requirements and strictly abide by relevant regulations.

　　To sum up, semi-enclosed hook sets may encounter common problems such as insufficient load-bearing capacity, poor lubrication, electrical system failures and lack of safety measures during use. These problems can be solved by evaluating and verifying load-bearing capacity, regularly checking lubrication systems and electrical systems, and establishing strict safety operating procedures, etc., to ensure the safe operation of the semi-enclosed hook group.
