What do the letters of each brand and model of excavator mean? I believe that many people who don't know much about construction machinery have had this question. In fact, the letters and numbers of each brand and model excavator have their specific meanings. After understanding the meaning of these numbers and letters, it will help to better understand the relevant information of the excavator.
Take these models as examples to introduce, 320D, ZX200-3G, PC200-8, DH215LC-7, I believe everyone will understand what these letters and numbers mean after the explanation.
In the 320 of Caterpillar 320D, the first 3 means "excavator". Each different product of Caterpillar is represented by a different number. This is also the difference between Caterpillar and the ** construction machinery manufacturer, for example "1" is a grader, "7" is an articulated truck, "8" is a bulldozer, and "9" is a loader.
Similarly, the letters in front of the ** brand excavators also represent the manufacturer's excavator code, Komatsu "PC" for the excavator, "WA" for the loader, and "D" for the bulldozer.
Hitachi’s excavator code name is "ZX", Doosan’s excavator code name is "DH", Kobelco is "SK", ** brand excavator models in front of the letters indicate the meaning of excavators.
After saying the previous letter, the next number should be "320D". What does 20 mean? 20 represents the tonnage of the excavator. The tonnage of the excavator is 20 tons. In PC200-8, 200 means 20 tons. In DH215LC-7, 215 means 21.5 tons, and so on.
The letter D behind 320D indicates which series of products it is. Caterpillar's latest series should be E series products.
PC200-8, -8 indicate the 8th generation products, but some domestic manufacturers may start directly from -7, -8 because the time is not long, so the meaning of this number is possible for many domestic manufacturers It doesn't make much sense.
These are basically the basic components of an excavator model, representing the number or letter of the excavator + the tonnage of the excavator + the series of the excavator / the first generation of the excavator.
In addition, some foreign manufacturers, in order to adapt to the specific working conditions in China, or the products specially produced by some manufacturers for specific working conditions, will also be indicated in the model, such as DH215LC-7, where LC means to extend the track, which is generally used for construction Soft ground conditions. "GC" in 320DGC means "general construction", including earthwork, river dam quarrying of sand and gravel (density ratio should not be too high), highway construction, and general railway construction. It is not suitable for environments such as harsh quarries. The "ME" in Caterpillar 324ME means a large-capacity configuration, including a short boom and an enlarged bucket.
symbol-plus numbers (such as -7, -9, etc.)
Japanese and Korean brands and domestic excavators are often seen-plus a number logo, which indicates the generation of this product. For example, the -8 in Komatsu PC200-8 indicates that it is Komatsu's 8th generation model. The -7 in Doosan DH300LC-7 indicates that it is Doosan’s seventh-generation model. Of course, many domestic manufacturers have produced excavators for only 10 years, and naming their excavators -7 or -8 is purely "follow the trend."
letter L
Many excavator models have the word "L". This L refers to the "extended crawler", which aims to increase the contact area between the crawler and the ground. It is generally used for construction conditions where the ground is soft.
letter LC
LC is a more common symbol in excavators. All brands have "LC" style excavators, such as Komatsu PC200LC-8, Doosan DX300LC-7, Yuchai YC230LC-8, Kobelco SK350LC-8 and so on.
letter H
In Hitachi Construction Machinery's excavator models, a logo similar to "ZX360H-3" can often be seen, where "H" means heavy-duty type, which is generally used in mining conditions. Among Hitachi Construction Machinery's products, the H-type adopts an increased-strength slewing platform and lower walking body, as well as a rock bucket and front working device as standard.
letter K
The letter "K" also appears in Hitachi Construction Machinery's excavator product models, such as "ZX210K-3" and "ZX330K-3", where "K" means the demolition type. K-type excavators are equipped with helmets and front protection devices to prevent Falling debris falls into the cab, and a lower walking protection device is installed to prevent metal from entering the track.
