How to extend the service life of the port crane correctly and effectively? How do you extend the service life of port crane? Many people may think that how can this basically open-air port crane control its service life? This practice is certainly unrealistic, but the fact is that it can be manipulated. Let's take the professional technicians of port machinery manufacturers with us to understand it.

The truck chassis of the port crane is a beam structure, which is dominated by bending stress. The stress is at the position where the core rotates and merges with the far side of the support foot, and the cross section of the truck chassis is a box structure. According to this specific situation, in addition to the integration of engineering construction regulations, people decided to choose their own opposite panels, horizontal plates to carry out plate structure reinforcement, and the two plates were welded with a suspension plate. In this way, the three plates produced a solid tripod structure. According to the calculation of basic theory, the compressive strength increased by more than 15%, taking into account the actual stress Use the rules.

When it comes to welding materials for port cranes, in fact, the materials are close to the crane materials, so as to ensure the actual effect of electric welding, and the characteristics of the materials should meet the requirements of compressive strength. After the raw materials are selected, the butt weld and new materials are sampled respectively, and then the electric welding is welded together to carry out the damage test. The result is that the butt weld is broken, which indicates that the compressive strength of part of the new materials and electric welding exceeds that of the butt weld, and ensures the construction quality and pressure resistance requirements of the project.

The key is to remove the heating, welding wire air drying, production and processing of structural reinforcement plate, secondary arc welding machine, welding engineering construction process and heat insulation after welding, so as to ensure the quality of engineering construction.

Check the welding position of the port crane for false welding and burn through, and whether it meets the application requirements. After the structure is reinforced, part of the parts should be inspected to distinguish the percentage of compressive strength improvement of the parts of the port crane truck chassis, and then compare with the actual 15%, so as to calculate whether the engineering construction is qualified or not.
