Can we tell the year of production by using the excavator serial number? How to tell the difference? Ask the experts for advice….

How to identify the true age and model of some excavators:

1. Modern excavators

The latest batch of Hyundai 60-5 is as of 06 In 2007, the production of 60-7 began. The 2008 model had 2 rows of heat dissipation holes on the right side of the body, while the 2007 model only had 1 row.

The first batch of Black King Kong was produced in 2009. The cab and tail were black. The production of 60-9 began in 2011.

130-5 was discontinued in 2007. Hyundai 200-5, 210-5, and 220-5 produced yellow pumps and yellow valves in 2002-03, and red pumps and red valves in 2004. , -7 was available in June 2004. Before the end of 2007, the position of the side door locks on both sides of the 225-7 was black. In 2008, it was yellow. In 2009, it was black King Kong, which means the black cab.

R150W-9 was produced in early 2011. The engine is Cummins B5.9C, and the front and rear drive axles and gearboxes are from German ZF. The price/performance ratio is good.

R215-9 was produced in December 2009. The 225LC-9 is powered by a Cummins EFI engine. The production time was from April 2010 to November 2010. Because EFI was not popular in the market, the production of direct injection machines began in 2011.

265-9 is EFI, 275 does not have -9, only -9T is a direct injection engine; 305-9 and 335-9 are Cummins EFI engines, 305-9T\335-9T is Cummins direct injection engine Injection engine; 385 and 485-9 are electronically controlled direct injection engines, -9T is electronically controlled direct injection engine; 455-7 and 505-7 are both electronically controlled direct injection Cummins engines.

There are not many original Korean cars on the market. Except for the nameplates of original cars, which are all in Korean, the inside of the cab door is white, while the inside of the domestic cab door is black.

2. Doosan excavator

Doosan product information: From 2003 to 2005, Doosan Daewoo’s logo and equipment model were all -5.

2006-2007 was the period of replacement between Doosan and Daewoo. The double slogans were all changed to the Doosan logo by the end of 2007!

From 2008 to 2010, most of them were -7 equipment, then -9, -9E, DX series appeared, and now the DX series -9C type machine.

3. Komatsu excavator is divided into large and small heads

Take PC200-6 as an example. The small head was produced in the early stage and uses Komatsu 6D95 engine, which is more fuel-efficient, but There are obvious flaws in power; the large nose is a later-produced Komatsu Cummins 6D102 engine, which has good power matching, so it has also been used in later models such as the 7-type aircraft. The environmentally friendly machine head is a small machine head with an air intake intercooler added, the same small machine head. This statement refers specifically to the Type 6 machine. Before Type 6, there was no large machine head, and after Type 6, there was no small machine head. (Small machine head: one valve cover for 6 cylinders; large machine head: 6 valve covers for 6 cylinders.)

There are also different hydraulic pumps for large and small machine heads. The small machine head is equipped with It is a Kawasaki pump (yellow pump), and the big machine head is equipped with a Komatsu pump (black pump). If the Komatsu 200-6 was produced before 2000, it will have a manual throttle, and after 2000, it will have an electric throttle.

The original Komatsu 60-7 generally has a large machine head, while the domestically produced ones have a small machine head.

The small window on the right rear side of the Komatsu 120-6 cab can be opened from top to bottom on the right side of the seat, because the He-5 has just been replaced and two anti-theft strips have not been installed on the outside. Protective tube. There is a round digital hour meter on the right side of the seat. The difference of -6E is that two anti-theft protection tubes are installed outside the small window. There is a black rectangular sticker on the body, and there are round numbers on the right side of the cab. The hour meter is gone, -6 is a small nose, and -6E is a large nose. The first batch of -6EO was produced in the second half of 2003. The engine cover is different from the -6, and the heat dissipation hole above the water tank is gone. -6E's engine is -1A1, -6EMO's engine is -2B2; and -6EO's battery valve angle is facing the hydraulic pump, while -6 and -6E are facing us, that is, you open the side door of the hydraulic pump , where you stand. The -6 and -6E fuel tanks are equipped with two verniers respectively, while the -6EO only has one hydraulic oil mark. No matter what year the -6EO was produced, as long as it is a real -6EO, it will have this configuration.

By 2005-07, the nameplate was all black, which was different from the previous nameplate.

Komatsu 200-7 was produced from 2002-2006 abroad and from 2003-2007 domestically. The nameplates before 2004 and after 2005 are different. In the lower right corner of the cab door, there is a keyhole on the body after 2005, which can be opened. Before 2005, there was no keyhole. If it is an original machine from 2004, you can use the key to open this small door. Generally, there are no fakes in this place. The main reason is that the counterfeiting is not good and it is more troublesome to deal with. The air-conditioning outlets behind the cab seats of the new -7 after 2005 are four round ones, the original ones are from 2004, and the old ones have four rectangular air outlets. The difference between the original car and the domestic car: 1. The cab seats are different. The original car has a silver-gray adjuster with numbers inside and an oval outside. The domestic one has a black round handle and a flat outside. , the original front and rear adjustment seat tie rods are parallel, and the domestic curvature is much higher; 2. Original cars are equipped with steering valves and escape valves. The steering valve is usually installed under the air filter behind the cab, but this is also It is easy to counterfeit. It can be bought in the market for less than 2,000 yuan. The escape valve is installed on the two oil cylinders of the big arm, and there are also oil cylinders in the small arm. This cost is very high and generally not counterfeited. The cost is high and the installation is troublesome; 3 The traveling motor of the original machine has 12 screws, and the traveling motor of the domestic car has 18 screws.

The Komatsu 300-7 and 360-7 engines, hydraulic pumps, and main control valves are the same. The 300-7 boom is flat, while the 360-7 boom has reinforced ribs and a crescent shape in the middle of the boom. The 360-7 has two more steel beams on both sides of the side beams, but the 300-7 does not. The 300-7CSE also has two steel beams, but the big arm is not like the reinforced ribs and crescent shape of the 360-7.

Komatsu 400-7 and above models are all EFI vehicles (including 400-7).

4. Carter excavator

The Carter series is divided into V, V2, and those produced before 1996. The B type was produced in 1996-2000, and the CU (the short-tailed one) was produced in 2001. species) and type C. Domestic production started in 2003. Taking 320C as an example, the domestically produced BPR without intercooler was produced before 2005; the domestically produced 320CGNG with intercooler was produced in 2006; and the 320CAMC was originally produced in Japan before 2005. If someone tells you that his 320C is original from Japan in 2006, you must not believe it, because Japan has already started producing D at this time. Hundreds of direct injection 320D were produced in the first half of 2007, and the performance is as good as Customer recognition is extremely high (as classic as Wong Ka Kui's song). Production of the EFI 320D began in the second half of the year. The fuel cylinder was yellow in 2007, and black starting in 2008. The engine cover was black in 2008-09, and the top of the cab was yellow. In 2010, the engine cover was yellow. When driving, The top of the chamber is black. Carter 325C and 330C are not highly rated in the market. They are EFI vehicles. You can tell the difference between original and imported by looking at the instrument panel. If the instrument panel is in Chinese or the machine that can call out Chinese is not imported. The original machines are all in Japanese and have no Chinese option. There is no radio in the domestic cab, but the imported radio is printed with the CAT logo. It is difficult to distinguish the 330D and 336D in appearance. They both have 7 rollers and both use Carter C9 engines. However, there are still differences if you look closely. The skylight on the top of the 336D cab is made of gray fiberglass, while the 330D is made of yellow iron. Furthermore, the 336D has a skid plate next to the fuel tank of the diesel tank, but the 330D does not.
