On many construction sites, we can see large bridge cranes of many specifications and models, through which we can complete tasks that people cannot complete. However, since the crane is a large-scale equipment, if there is any problem during use, the consequences will be very serious.

The impurities that adversely affect the crane are mainly non-metallic materials such as dust and dirt, metal shavings, wear products, etc. When these impurities enter the crane, they will not only hinder the normal operation of the various components of the equipment and accelerate wear; they will also damage the equipment. The most obvious manifestations are the temperature rise of parts and the deterioration of lubricating oil.

Secondly, you must use high-quality and applicable lubricating products to reduce the existence of impurities;

Therefore, it is necessary to pay attention to the safe operation rules of the double-girder bridge crane.

With the development of society, the industry develops rapidly. Large-scale lifting equipment is used more and more widely in various industries, giving full play to its unique advantages. However, when paying attention to the economic benefits of large-scale lifting equipment, the daily maintenance of large-scale cranes cannot be ignored. Only by doing this well can large lifting equipment work better. The daily inspection can focus on the reliability of the brake, the flexibility and accuracy of the safety protection switch and limit switch, the installation status of the wire rope, and the abnormal noise of the organization's operation, etc.

The complexity and urgency of crane equipment repair is a kind of active repair and condition repair mechanism of crane equipment repair. Condition-based maintenance is the use of different information from equipment to determine the location and cause of a failure when the equipment is running or not disassembled at all. Condition detection avoids sudden failure and forced shutdown of large lifting equipment, affecting production. Prepare repair parts in time, organize repair plans, and shorten repair cycle.
