Therefore, as long as you understand the type of accessories required for the excavator, you can purchase the most suitable excavator accessories. It is best to bring the original parts when buying excavator accessories for reference and comparison. Most excavator accessories have standardized types and technical parameters. It is best to have the best compatibility in terms of information, scale, or quality when selecting new accessories.

In order to prevent delays in the operation and improve work efficiency, it is best to have experienced personnel accompany the purchase of excavator accessories to minimize the risk.

Method for distinguishing authenticity

Domestic excavator parts are divided into original parts, supporting parts, and auxiliary parts. The parts purchased by the main manufacturer from the supporting manufacturer and sold as after-sales maintenance parts are called pure parts, with guaranteed quality but expensive prices. The original OEM parts that come with the host are sourced from the same manufacturer as the pure parts, with the same quality and only different packaging, but at a lower price than the pure parts. However, due to the high prices of original and supporting parts, many users often choose to replace their cars with aftermarket parts after the warranty period, considering the cost issue. Accessory parts refer to accessories produced by manufacturers who are not authorized by the manufacturer. They are labeled with their own factory name and trademark, but do not have the manufacturer's brand logo. They will be labeled as "applicable to XX and XX models". These auxiliary components are generally produced by small factories, but there are also some produced by world-renowned manufacturers.

There are divergent opinions among users regarding whether to choose original or auxiliary parts. Some users advocate using pure original parts to protect the machine to the greatest extent possible. But there are also users who advocate that in addition to using original parts for important components, some unimportant domestic excavator parts can also be replaced with aftermarket parts.

Judging from the price, the price of counterfeit goods is generally only a fraction of that of genuine goods. If you find that the price of the product is significantly different from the normal price when buying accessories, you should be more vigilant. In addition, if a merchant says things like 'no tax included' or 'parallel imports', it is often an excuse to cover up and impersonate fake and inferior products, tempting people to take the bait at a low price.

Based on packaging identification, the packaging of professional accessory factories is exquisitely manufactured, with certain rules for color, pattern, and style, making it difficult to copy the same. The packaging for copying is relatively rough and easy to distinguish. But some copyists rely on modern advanced printing technology to make the packaging of parts very vivid, and if not carefully identified, it is also difficult to distinguish.

Mechanical components generally have outer packaging and inner packaging, with outer packaging consisting of packaging boxes and packaging boxes; The inner packaging is usually made of labeled packaging paper and plastic or paper bags. The outer packaging boxes (boxes) of pure imported accessories are affixed with the manufacturer's common label, clear printing, excellent paper quality, and marked with part numbers, titles, quantities, manufacturers, and countries. The copied label printing is not precise, and the colors are either light or heavy, making it difficult to match with pure packaging. By using computer printed part numbers and manufacturer marked colors that are either light or heavy, careful identification can distinguish between authenticity.
