The importance of small bolts on excavators

The strength of China's infrastructure is beyond doubt, and China's excavator technology is also well-known. As the main construction machinery in engineering construction, the importance of excavators goes without saying. So, what should be paid attention to when using various bolts of different sizes on excavators?

Many people, when repairing and maintaining excavators, will go to the original factory to replace large parts that are broken, while for some small bolts and screws that need to be replaced, they can simply find a replacement of the same specification. It is precisely because of this mindset that excavators continue to malfunction frequently even after repairs. This is because many bolts used on excavators have high requirements for performance and quality, and finding them randomly on the market may not necessarily meet actual usage needs. Many parts of the excavator require the use of "fine buckle" bolts, copper plated bolts, and copper bolts. If ordinary bolts are used instead, problems such as loosening, detachment, and difficulty in disassembly may occur. Some bolts may also be stretched and deformed during use. If this is repeated, it is surprising that the excavator does not malfunction. In addition, there are some special bolts on excavators that require high strength and toughness, which require special materials and special processing techniques, such as engine crankshaft bolts, cylinder head bolts, connecting rod bolts, flywheel bolts, nozzle fixing bolts, etc.
