Professional excavator driver recruitment platform - [special hunting driver market], looking for a job to recruit machine hand, local live, local machine hand pick at will! Based on the experience of diggers, the quality reference of domestic excavators is given as follows:
advantages: strong strength, reasonable design of hydraulic pipes of big and small arms
disadvantages: slow movement of forearm, expensive parts, small fuel tank, and after-sales service need to be strengthened
according to the feedback of many machine owners, we find that there is a problem in the vast majority of domestic excavators: there are no major problems, and there are many minor problems. This makes the operators quite helpless. We hope that the major manufacturers will pay more attention to details in design and communicate with users. In addition, most domestic excavator brands still have a common problem: the level of after-sales service needs to be improved. Sany's after-sales service is the most satisfactory, which has become one of the key factors for Sany excavator to stand out when the quality of excavator is similar
5.
1、 Sany excavator has more than 1000 high-end R & D engineers and more than 40 foreign experts, and has established the largest and most advanced R & D test system in China
Sany Heavy Machinery has developed 200 ton hydraulic excavators, hybrid hydraulic excavators, new generation positive flow excavators, pure electric small excavators and other innovative procts with world-class standards. Sany Heavy Machinery excavator model has covered 1.5t-200t large, medium and small digging three series, more than 20 varieties Xuzhou Construction Machinery Group Co., Ltd., founded in March 1989, has always maintained the leading position in China's construction machinery instry since its establishment for 30 years. At present, it ranks fifth in the world's construction machinery instry, 150th in China's top 500 enterprises, and 55th in China's manufacturing instry. It is the largest construction machinery instry in China with the most complete proct varieties and series The most competitive and influential large enterprise group According to the scale, excavators can be divided into large excavators, medium excavators and small excavators According to the different walking modes, excavators can be divided into Crawler excavators and wheel excavators According to different transmission modes, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines According to the use, excavators can be divided into general excavators, mining excavators, marine excavators and special excavators6. Domestic excavator? Suppose we don't include Japanese, Korean, European and American joint ventures in China
mainstream brands of domestic excavators include Liugong, Sany, Zoomlion, Zhanyang, Yuchai, Shanhe intelligent, Xiagong, Fu, Shanzhong, etc< The main limitations of domestic excavators are as follows:
1. There is no stable supporting system. At present, it mainly relies on foreign supporting plants such as Japan or South Korea. The domestic supporting system is not perfect and the quality is not hard
2. Compared with the design precipitation of foreign countries in the past few decades, the technology is not stable enough and the action is not coordinated enough. The fuel consumption, proctivity and resial value obviously can not compete with the joint venture / foreign investment
3. The quality control in proction is not precise enough, and the proction personnel are not stable enough, which leads to rough procts and unstable performance
4. In marketing, we mainly rely on event marketing and deceptive marketing, without long-term strategic vision, but in the current "food grabbing" stage, it is also an advantage
5. In terms of service, because of the unstable quality, the workload of the service system is huge, and if the salary is not attractive enough, the staff turnover rate will be difficult to control< Now let's talk about the quality ranking:
1. The main player: Yuchai & gt; Shanhe Intelligence & gt; Liu Gong, others are almost the same< 2. Medium excavation: Liugong & gt; Xiagong & gt; Zhan Yang & gt; Sany & gt; Zoomlion & gt; Mountain weight & gt; Caressing and digging
3. Digger: I hope we can see a domestic digger that can barely hold the hand. Let's talk about it
focus on Sany, Sany's marketing strength is incomparable, but only from the quality point of view, I dare not compliment you
finally, give a pertinent suggestion to domestic manufacturers: do the car down-to-earth, honest sales, don't cheat, customers are not fools
I hope it can help you, thank you!

7. 1. Look at the appearance
first, when you look at an old equipment, you can see the color of some paint and the wear of the walking part of the equipment through different light and angle, whether the gun barrel has been installed in the appearance, whether the pipeline is original or installed after you, and the wear of the counterweight, including the side door, counterweight and paint, Judge by different light angles. The appearance problem can be said to be a small matter or a big matter. When others ask for equipment construction, it must depend on the old and new level of your equipment. At the same price, people will never abandon the new and choose the old
2. Look at the name plate
when buying a second-class mobile phone, most people will habitually look at the name plate. The name plate of the equipment is just like the ID card of our citizens. Its nature is the same, with the model and factory code of the relevant equipment on it. In the picture, Japan represents the proction place of the equipment, and its proction date can be found by the equipment code
3. Look at the steel seal
it can be seen on some important structural parts. This is the vehicle identification number (frame number). It can be seen at the root of the boom, the frame, the oil tank and other parts of the excavator. Generally, it is steel seal. According to this, you can inquire the date of manufacture of the equipment through the equipment dealer or manufacturer. Steel seal is a problem ignored by many people. It is as important as the name plate of equipment. The steel seal is not easy to be changed unless it is broken by the polisher
4. Hour table: it can be compared according to the year of the equipment and the hour of the display. The average usage hours of an excavator is about 2000 hours per year
in addition, regional differences also have a great impact on the service hours of excavators. Because the frozen soil doesn't work in winter, the number of hours of the same age machine in Northeast China is less than that in South China. You have to be careful if you come across a machine in the mine. According to the data of collecting the car, the machine is very young, and the mechanism parts look very eye-catching, but the mining machine usually operates 24 hours a day, so this kind of machine has been sold to coolie
5. Look at the fuselage
(1) look at the counterweight: the counterweight is commonly known as "butt" by the hands. The quality of counterweight reflects whether a driver cherishes the equipment and the construction environment of the equipment. It is normal that the paint under the normal construction equipment will be worn off after more than 3 years. If the counterweight of the machine is completely scratched, or the iron sheet outside is broken, this kind of equipment has been in the mine, or engaged in Demolition for a long time, or broken equipment, normal excavation, simple earthwork engineering will not appear this situation
(2) both sides of the fuselage: pay attention to whether the sheet metal has been made, If so, there was a strong collision
(3) cab: pay attention to whether there are collision marks between the cab and the door. If there has been a rollover or a stone hit equipment ring construction, it will not be so upright
(4) engine cover: if you look at the construction environment of the equipment in summer, you should pay attention to the contents in the red box of the above figure. If the water level of the equipment is always very high and the engine hood is opened for a long time, the water temperature of the equipment must be too high! If the engine often has problems, the cover is opened frequently and for a long time, which is more likely to be damaged
6. Excavator interior and display: sometimes the seller will say that the display is broken. In this case, you'd better not believe it. Many of them don't have a computer board. When you buy it back and want to repair the computer board, you will be wronged! It's better to buy a second-hand computer board than tens of thousands. It's not necessarily as good as the original one
7. Engine is the heart of excavator. To see if the engine has been removed, it is necessary to carefully check whether the installation position of the engine screws and the surrounding parts are the same as those of the original factory. It is also necessary to check whether the information on the engine and radiator nameplates has been changed, whether the valve cover has been removed, whether the diesel pump leaks oil, whether the wiring harness is neat, whether the belt and fan are damaged, whether the water tank cover is rusted, and whether the cotton sliver on the engine hood is damaged
the picture shows a Isuzu engine with a brand name plate replaced. The brand name plate on the new one is still torn. The engine proction date is usually marked on the engine nameplate. If the information on the nameplate in the figure above is true, it can be inferred that the date of manufacture of this equipment should be the end of 2011 or the beginning of 2012
when the engine is running, the size of its lower exhaust should be considered. If it's big, the engine needs to be disassembled for repair. Check whether the engine oil is burned, and see the smell and color of the gas at the exhaust port on the engine
8. Look at the water tank
if you find that there is a layer of yellow material around the water tank, it means that this excavator often has the problem of high water temperature
9. Radiators
whether it's the radiator of hydraulic system or water tank, if it's the original factory's radiator, if it's a new one, you should pay attention to it. Some of them are not only high in water temperature, but also high in hydraulic temperature
10. Hydraulic pipeline:
hydraulic pipe, distribution valve, rotating parts, no matter what age of the machine, depends on how many pipes are from the original factory. If it is a replaced pipe, it is necessary to carefully look at its connection position, so as to determine what fault it will have. This is ignored by many friends. Whether the maintenance of an equipment is good or not can be seen directly from here
(1) check the hydraulic pump: judge whether it is the original pump or the replaced pump, whether it has been repaired, and observe from the paint, oil pipe joint, flow regulator, etc
(2) check the hydraulic condition: two people cooperate, one for test run, and the other for feeling the vibration of each oil pipe by hand (3) check the distributor, rotary motor, rotary recer, etc; Observe whether the oil pipes and screws are original ones; Observe the dipstick and feel the viscosity by hand
11. Big pump
"don't think that a new total achievement is worth buying, the original thing is the best. If the whole pump of the equipment is knocked out, its position is not only here, but also related to the distribution valve. If it is knocked out suddenly, the iron filings will flow in the hydraulic oil. If it is not handled properly, the whole hydraulic system will be scrapped! "
12. The construction environment of the equipment can also be seen in the walking part of the walking device. Take a closer look at the corner of the motor in the blue circle. The standard earth moving equipment is worn. If it is in the mine or engaged in crushing, construction waste construction environment, it will round the corner
13. The wear degree is determined by the angle of the track shoe. The equipment of earthwork is worn at right angles, and the equipment of stonework construction environment is basically ground flat. Some equipment hours are not much, but the crawler shoes are severely worn. It is possible that there are many stonework construction and the equipment travel time is long. Long time walking wear motor prone to problems!

8. I was born in 2015. In the first year, there was no problem with the new machine. In the past two years, there have been intermittent small problems. After all, the price is still better. Compared with the imported machine, it's not very good, but I know that the price of the imported machine can buy three such domestic machines
