In the process of using and maintaining the excavator, the selection of accessories is very important. Today, I will talk to you about the doorway in this.
In terms of the quality of accessories, you should choose a formal channel. Give priority to the official authorized dealers or after-sales service centers of the excavator brand, which can ensure the quality and compatibility of the accessories. For example, if you buy the accessories of Komatsu excavators from official authorized stores, you can ensure that they are genuine products produced by the original factory or approved by the original factory. Formal second-hand dealers can also be one of the channels to choose. Some well-known and reputable second-hand dealers will test and sort the available accessories obtained from the dismantled equipment after purchasing second-hand equipment. The quality of these screened accessories is guaranteed and the price may be relatively low. For example, "XX Second-hand Engineering Equipment Trading Center" has strict processing procedures and standards. At the same time, you should also check the quality certification and check whether the accessories have quality system certifications such as ISO 9001. For key components such as engine parts, hydraulic components, etc., the quality certification mark can guarantee their quality and reliability. Both new accessories and accessories purchased from formal second-hand dealers should pay attention to this. In addition, the appearance and workmanship of the accessories should be carefully checked to see if there are any flaws, rough processing marks or obvious wear. For example, the gear accessories should be checked for tooth surface smoothness and cracks, and the seals should be checked for surface flatness and deformation. If purchased from a second-hand dealer, it is even more necessary to check carefully to ensure that there is no excessive wear or damage in previous use.
In terms of adaptability, the model and specifications must be checked to ensure that the accessories match the model, production year and specific configuration of the excavator. Different models of excavators may have different accessories even if they are of the same brand. For example, some accessories of the Caterpillar 320D and 320E series cannot be used universally. Second-hand dealers should also clearly inform the range of compatible models when selling accessories. Compatibility should also be considered. If the excavator has been modified or upgraded, the compatibility of the new accessories with the original equipment should be considered when purchasing accessories. Second-hand dealers should provide reasonable suggestions based on their professional experience. In terms of price, you cannot choose accessories just because they are cheap. Too low a price may mean poor quality, counterfeit or refurbished parts. For example, a hydraulic pump with a price far lower than normal in the market may be a refurbished old pump. Its performance and service life are not as good as new original accessories. When buying from a second-hand dealer, you must also judge whether the price is reasonable. At the same time, you can consult multiple regular suppliers for prices to understand the market situation, but you must comprehensively consider factors such as the supplier's reputation and after-sales service, including the reputation evaluation of second-hand dealers.
In terms of after-sales service, you must ask for after-sales guarantees and understand the return and exchange policies and warranty periods provided by suppliers. For example, some suppliers provide warranty periods ranging from 3 months to 1 year, and regular second-hand dealers should also provide after-sales guarantees for the accessories they sell. When purchasing accessories, be sure to ask for and keep invoices, receipts, product certificates and other documents. This can be used as a basis for rights protection when quality problems or disputes arise. This cannot be ignored whether it is a new accessory or a second-hand dealer.
In short, purchasing excavator accessories requires a comprehensive evaluation of factors such as quality, adaptability, price and after-sales service, so that you can choose suitable accessories to ensure the normal operation and service life of the excavator.
