Common faults of small excavator

Small excavators are commonly used construction machinery, which can work in a narrow space. However, due to the short service life of small excavators and their vulnerability to damage, regular maintenance is required.Generally speaking, the maintenance of small excavators includes daily maintenance, regular maintenance and special maintenance. Routine maintenance is essential, including regular inspection of machine parts, start-up test before use and shutdown test after use. Regular maintenance is generally carried out once a year or half a year, and the main purpose is to carry out a detailed overhaul of the whole machine. The special maintenance is to carry out some specific maintenance work under specific use conditions (such as long time work, large amount of use, and abnormal conditions).Small excavators are very practical, but there are also some failures. Small excavators are common construction equipment and are also vulnerable to damage. Let's look at the common faults of small excavators.The peculiar smell inside the cab is caused by the filter element of the small excavator that cannot be replaced in time or the filter element has been blocked. In addition, because the seal of the small excavator is not tight, it will also lead to peculiar smell inside the cab.Engine oil burning is caused by the leakage of engine cooling water or the tightness of engine air brake. If the air brake of the engine is not tight, the engine cooling water will leak, which will cause the engine to burn oil.The insufficient air intake of small excavators will also cause engine oil burning. There are many reasons for this situation, including engine air brake leakage, brake pad looseness, inductance switch failure, flywheel brake, flywheel failure, flywheel start, flywheel brake pad looseness and other reasons. If you want to repair this problem, you must repair it according to the specific situation.There are many reasons for this situation, such as cracking of the wrap disc, loose flying disc, loose large disc, loose large disc brake pad, loose transmission belt and other reasons. To fix this problem, we must repair it according to the specific situation.

The sales volume of small excavators is expected to reach a record high in October 2020

According to the latest statistics of China Construction Machinery Industry Association, in September this year, 25 excavator manufacturers included in the statistics sold 26000 excavators of all kinds, up 64.8% year on year. Among them, the domestic sales volume was 22600, up 71.4% year on year; 3436 sets were exported, up 31.3% year on year.In the first nine months of this year, a total of 236500 excavators were sold in China, an increase of 32% year on year, which has exceeded the sales of the whole year last year. Among them, the domestic sales volume was 212800 units, up 33.2% year on year; 23700 sets were exported, up 22.2% year on year.This means that the sales of domestic excavators will hit a new record this year.In 2019, the sales of domestic excavators reached 235700 units, up 15.9% year on year, breaking the sales record of 203000 units in 2018.Since this year, the year-on-year growth rate of monthly excavator sales has exceeded 50% for six consecutive months.In January and February, affected by the COVID-19, the sales volume of domestic excavators declined sharply, but after March, the double-digit growth was achieved against the trend, and after April, the sales growth continued to exceed 50%.In April, 25 excavator manufacturers included in the Association's statistics sold 45400 excavators of all kinds, with a year-on-year growth rate of 59.9%; In May, the sales of excavators still maintained a good momentum, reaching 31700 units, with a year-on-year growth rate of 68%.In June, the sales volume of excavators was 24600, up 62.9% year on year; The sales volume of excavators in July was 19100, up 54.8% year on year; In August, the sales volume of excavators was 209 thousand, up 51.3% year on year.Many institutions predicted that under the influence of a number of favorable policies, the construction machinery industry will maintain a high outlook.The construction machinery industry is one of the important industries in China's machinery industry. Its product market demand is greatly affected by the national infrastructure construction, and its downstream customers are mainly concentrated in infrastructure, real estate and other investment-intensive industries, which are closely related to the macroeconomic cycle.The sales manager of excavators in Shandong Province once told Interface News that the current tightening of environmental policies is a major factor affecting the recent surge in excavator sales.Since this year, domestic excavators have implemented the fourth national emission standard. GF Securities once estimated that among the domestic excavator holdings, there are about 800000 in the first and second emission standards. If all of these machines are eliminated in the next five years, the average annual replacement volume will reach about 160000, and the demand for replacement is still relatively strong.Soochow Securities pointed out that in October, the production scheduling of construction machinery core parts manufacturers increased by more than 40% year on year, still showing a high growth rate. With the arrival of the fourth quarter of the stock season and the gradual emergence of the effect of infrastructure recovery, it is expected that the sales of excavators will continue to maintain a strong trend.Soochow Securities said that under the background of the continuous demand for the renewal of old excavators, the improvement of the replacement effect of excavators on loaders, and the non-pessimistic investment in real estate infrastructure, the annual sales of excavators in China is expected to reach more than 300000, with a year-on-year increase of more than 30%.Galaxy Securities pointed out that with the gradual easing of the epidemic and the gradual recovery of the economy, the market's expectation of the reverse cycle of infrastructure investment has weakened, but from the perspective of forward-looking indicators, the sales growth of excavators and heavy trucks is still strong. Under the background of accelerated construction of major projects in the second half of the year, it is expected that the infrastructure investment in the second half of the year will further develop.According to TianyanchaAPP data, in the past decade, the number of excavator-related enterprises (all enterprises) in China has increased from 10000 to 56000, an increase of nearly five times, and the number of new enterprises has increased year by year.

With the increasing number of domestic excavators, where will excavators go? Investment pressure

In recent years, in the domestic excavator machinery market, the purchase boom of wheeled excavators has increased year by year. With the strong promotion of national policies, the rapid development of new rural construction and the new reconstruction of rural roads have overwhelmingly carried out the price of wheeled small excavators. It is expected that the sales of wheeled excavators in the country will show an increasing trend in the next decade.The advantage of the wheel excavator is that it is easy to walk, unlike the combination of the crawler truck and the trailer, but now the traffic is convenient. Does the wheel excavator need a driver's license to walk on the road? Where do I get the license? What kind of license?Excavators belong to construction machinery, but are different from forklifts and loaders. Many regulations have not clearly pointed out where the wheel excavator went? Will I be prosecuted for walking on the road?At present, in the national market, Tianjin, Liaoning, Jilin, Guangdong and other regions, the road traffic management department of wheeled excavator will investigate and deal with unlicensed vehicles. Traffic control has not yet appeared in most other regions. After all, there are no clear regulations.With the increasing number of domestic wheel excavators, traffic control is only a matter of time. Customers who buy wheel models should consider this factor from a long-term perspective when purchasing a car. Why do you say that because it involves taxes, licenses and other contents and expenses?Take Shenyang City, Liaoning Province as an example, the wheel excavator must pay tax before applying for the license plate, which is the same as the purchase of private cars, but the tax rate of the wheel excavator model is 10% of the cost of the car purchase, that is to say, 20000 tax will be paid for 200000 cars, which undoubtedly adds a layer of investment pressure to the buyers.In this way, customers who want to buy a car still have to choose calmly, because some domestic brand models are duty-free. Of course, the manufacturer and model must be formal, and must pass the review of the National Locomotive Center and the State Administration of Taxation.As far as I know, the wheel excavator of Baoding brand in Texas is tax-free, so its wheel excavator is very popular in many traffic. The reason for the control area is that it is not easy to get money from anyone after all, and the avoidable investment should be avoided.

The traveling speed of foreign wheel excavation is mostly 25-40 km/h

With the redefinition of China's urban construction process by the "new urbanization" strategy, the demand of China's construction machinery market is also quietly changing. Wheel-type excavators have attracted more and more attention in the industry and become one of the strategic development products of many leading construction machinery enterprises.The wheel excavator is a kind of construction type wheel and tire walking excavator with fast walking speed, long-distance self-transition and quick replacement of various operating devices. The advantages of mobility, flexibility and efficiency have won customers' favor. At present, the driving speed of foreign wheel excavators is mostly 25-40 km/h, and most of the domestic wheel excavators are 20-35 km/h, some of which can even reach 54 km/h. It can be said that although wheel excavator does not occupy the mainstream position in China, its technical level is not backward.Excavator pictureAdvantages and disadvantages of wheel type excavatorAdvantages: high speed and long distance autorotation, general speed up to 40-50KM/H, mobile and flexible characteristics, fast replacement of a variety of operating devices, no damage to road characteristics, suitable for hard ground construction.Compared with the crawler hydraulic excavator, the disadvantages are: high price, low efficiency, poor stability, poor safety, poor heat resistance, inability to enter the mine or muddy areas, and poor climbing ability.The mainstream of the wheel excavator market is 15-17 tons of products, and the small excavator market is 6-8 tons.The main technical difference between domestic brand products and foreign brand products is the bridge box technology. The service life of domestic products is shorter than that of foreign brand products.Wheel excavator is applicable to urban water supply, municipal, pipeline maintenance engineering, civil engineering, industrial material handling, tunnel excavation, water conservancy engineering, urban demolition, etc.Excavator pictureDifference between wheeled excavator and crawler excavatorIt mainly depends on the occasions you use, and each has its own advantages. But now more and more people like crawler excavators. Although the mobility of the crawler excavator is poor, it is not necessary to use the wheel type of the wheel excavator for long-distance transportation. There are special transport vehicles; If the price of small wheeled excavator is walking on the construction site, the crawler excavator may be better.Wheel - action is not as fast as track, rotation is not as large as track, wheel - is 180 degrees,<@ track rotates 360 degrees freely.The wheel type can be used for road driving, but the track type cannot be used. The wheel type is more convenient.But the track can work on the mountain, let alone the wheel style.In addition, the power and trafficability of the wheel type is not as good as that of the track. The track can go up a right angle slope and is not easily restricted by the soil.

How many operating tips do you know about small excavators?!

With the partial restriction of large machinery in cities and the increase of operation methods of excavators in rural engineering projects, small excavators are becoming more and more popular in rural areas due to their flexible and versatile characteristics. Excavator market, but in fact, many excavator drivers' operating skills have not reached such a high level. In fact, many operating skills need time to hone. Today, I will teach you some operating skills of excavators, which is very fast to learn.1: Effective mining methodsWhat is effective? In fact, many excavator drivers do not dig effectively when using the excavator, because when they directly contact the soil with the bucket teeth of the excavator, they often feel that they do not exert full force on the excavator, which may be the reason for the contact angle between the bucket teeth and the soil. Yes, the force of the excavator is not reflected in the excavation process, resulting in no effective excavation, so the efficiency is relatively poor. In fact, the bucket teeth should be at an angle of 30 degrees with the object to be excavated, so as to minimize the excavation resistance, and the excavator can make full use of the force.2: Don't use brute force to dig stonesIn fact, the excavator is forbidden to excavate rocks, because the rocks are hard, which will cause wear between the excavator bucket and the rocks. Generally, a crusher should be used to break the rock before excavation. If the excavator needs to be used directly for excavation, the bucket should be inserted into the rock gap for excavation, and the force of the bucket and forearm should be used to reduce the damage of the rock to the bucket.3: Slope levelingMany people find it very difficult to work on the equality project because it is a relatively detailed work. When training, the excavator should be balanced. If the excavator is unbalanced, it can be leveled no matter what you do. In addition, by keeping both hands coordinated, the excavator bucket can be adjusted to a relatively stable position, and the excavator rotation can be used for leveling, correction and inspection.4: Load operationWhen using an excavator for loading, first adjust the position of the excavator and truck to ensure that it can be loaded with the minimum rotation angle, so that the loading efficiency will be higher. The second is to ensure that the position of the excavator is higher than that of the truck, because the excavator driver has better vision and more convenient operation.5: Work in soft places or waterIn fact, the excavator driver should check the construction site before each construction. If you find that the construction site is soft, muddy or working directly in the water, you should prepare wooden boards and other items in advance to stabilize the excavator pad. If you are driving a crawler excavator, remember not to let the water track, because the water may enter the engine compartment and cause electrical failure.I believe that many experienced drivers understand the skills and experience of excavator operation. Only by practicing hard and accumulating experience can we continuously hone our skills and become a better driver.

What is unusual about small excavators?

Small excavators, mini excavators and small excavators, with their lightweight characteristics, have begun to come into people's eyes. They have become new favorites in many construction sites. They are not only beautiful in appearance, but also small in size. They play a very good role in daily operation. But what are the special features of this kind of equipment? The reason why small excavators and micro excavators can successfully defeat large excavators is that they have a wide range of uses. First of all, excavation is indispensable in the current construction project. The common ones are civil engineering, agricultural landscape, and garden landscape. With their small body, they will not be limited by the construction space. Even small space can also enter the stage of operation. Small excavators can not only play a role in excavation, but also catch wood, hay, or smash walls, so they can be seen everywhere in the current rural market. The reason why people have a high recognition of small excavators is that with the increase of economic pressure, if you choose a large excavator, you need not only to invest a higher cost, but also need to pay for the later maintenance costs. However, selecting a small excavator has a relatively low investment and is very fast when working. It can effectively save labor costs and reduce economic investment. Therefore, small excavators can be seen in many construction sites.

The sales of small excavation in 2016, 2017 and 2018 continued to rise as the construction machinery industry continued to heat up. Comparison of domestic excavator sales in 2012-2015, engineeringHow much can I buy an excavator? This problem is very broad, because there are different types of small excavatorsAccording to the classification standard of the Excavator Branch of the Construction Machinery Industry Association, the small excavation excavatorIn 2018, the sales volume of domestic excavator market reached Taiwan (excluding Hong Kong, Macao and Taiwan), with a year-on-year increase of 41.1%, setting a new record for historical sales volume. The excavator market, which has frequently heard good news, is booming.Behind the scenery, what supports the excavator's large volume?Sales of small mines in 2016-2018Taiwan, accounting for 59%, has achieved remarkable performance in 2018. The review of 2016 reflects Xiaowa's recent excellent performance and huge market potential. On April 2, 2019, the award ceremony of the "Top 5 Engineering Machinery Products of the Year (2019)" will be held in Beijing. What are the achievements of small mining opportunities? How to predict future performance? Coming soon! The power of small excavators is beyond imagination. Sohu small excavators can dig/break/grab wood drill/rake grass/consolidate. They are powerful and extraordinary. Compared with the previous ones, the small digging products this time have significantly improved. At the same time, the sales data of small excavators since the construction machinery industry began to recover. The sales volume of small excavation in Taiwan in 2016, the sales volume of small excavation in 2017 and the sales volume of small excavation in 2018 continued to rise with the continuous warming of the construction machinery industry.From 2012 to 2015, the construction machinery industry began to decline and entered the freezing point period, and the proportion of small excavation sales continued to rise. The domestic excavator market sales reached Taiwan (excluding Hong Kong, Macao and Taiwan), with a year-on-year growth of 41.1%, breaking the historical sales record. The excavator market with frequent good news is booming. Behind the scenery, what supports the excavator's large volume? From 2016 to 2018, the sales volume of small mines was 59%. Small excavators have made remarkable achievements in 2018. Reviewing the advantages of the construction machinery industry since 2016, it is very suitable for construction sites with small space. In 2018, liter. Since 2016, the market has entered a recovery period,From 2012 to 2015, the proportion of small excavation sales continued to rise. It can be understood that due to different application fields, large-tonnage excavators are greatly affected by investment and economic cycle, while small-tonnage excavators are relatively less affected by investment The market recovery since the second half of 2016 was affected by multiple factors. Due to the high technical barriers and market access barriers, the market is more occupied by leading enterprises in Europe, America, Japan and China, resulting in a higher concentration of the domestic large mining market than the medium-sized market. Dig and tap the market. The market concentration of medium and small mines is close to the overall market concentration, and the market competition is relatively fierce. As an annual event to promote the technological progress of construction machinery and reflect the market demand of construction machinery, this time it appeared in the "Top 5 Annual Products of Construction Machinery (2019)", which has significantly improved compared with the past. At the same time, it also reflects Xiaowa's outstanding performance and great potential in the market recently. On April 2, 2019, the award ceremony of "Top 5 (2019) Annual Products of Construction Machinery" will be held in Beijing. What achievements will small excavators achieve? How to predict future performance? Coming soon! Small earth stone engineering, municipal engineering, pavement repair, concrete crushing, buried cable, automatic driving, among which investment growth is one of the important factors. Therefore, in this round of market recovery, the recovery of medium and large mines is more significant, and the market share has also increased. In 2018, the domestic sales innovation of excavators reached a new level. It reached a record high, but the proportion of small sales volume in 2011 was significantly higher than that in the previous period. And the market share has also increased. In 2018, the domestic sales innovation of excavators reached a new level. It reached a record high, but the proportion of small sales volume in 2011 was significantly higher than that in the previous period. How can small excavators maintain a high proportion in such a huge excavator market? The factors that promote and maintain the sales growth of small excavators include the landscaping of municipal departments, the planting and digging of orchard nurseries, the breaking of concrete pavement, the mixing of sand and gravel, and the construction of small space, Adopt quick-change joint, optional rotary drill, crushing hammer, loading bucket, grab and other accessories, reduce maintenance and operation costs, liberate labor force, improve the degree of mechanization, with low investment and high return. In recent years, there are more and more small excavators on the market. It has promoted the rapid growth of the number of small projects in China, and the recovery of the small excavator market is driven by multiple factors, among which the investment growth is one of the important factors. So what?1、 Brand strategyAccording to Jiangke Construction Machinery, some industry leading group manufacturers take small digging as one of the ways to build and promote brands. Make sufficient investment in the R&D and manufacturing of Xiaowa, continuously optimize and improve Xiaowa's products, make Xiaowa's quality and performance reach the leading position in the industry, establish good business performance, spread the brand, and establish good performance through the huge flow of Xiaowa., Even taking a certain model as a key model is not because the aircraft is not insured, which facilitates the inflow of cash flow and supports the normal operation of the enterprise. Therefore, manufacturers regard small mines as one of the important sources of cash flow, so they will pay more attention to the sales of small mines. 3、 Objectively, the advantages of small excavation in modern construction operations 1. High efficiency, deepening urbanization process, and small construction machinery in the field of mechanical power generation, as a rising star, have begun to partially replace its position in the construction of large and medium-sized machinery, and are generally welcomed by users. With the advancement of China's urbanization process, the output will be reflected. In this way, the engine is very good, and the converted hydraulic energy can be profitable in general oil. As a rising star in the field of machinery replacement, small construction machinery began to partially replace its position in the construction of large machinery, and was generally welcomed by users. With the advancement of China's urbanization process, the output will be reflected. In this way, the engine is very good, and the converted hydraulic energy can be profitable in general oil. As a rising star in the field of machinery replacement, small construction machinery began to partially replace its position in the construction of large machinery, and was generally welcomed by users. With the advancement of China's urbanization process, the output will be reflected. In this way, the engine is very good, and the converted hydraulic energy can be profitable in general oil.2、 Cash flow strategyCash flow is an important guarantee for enterprises to ensure their survival and development and improve their market competitiveness. Cash flow measures whether the enterprise is in good operating condition, whether it has enough cash to repay debts, and the ability to realize assets. Cash flow is very important. Index.In the last cycle, debt risk has been plagued by many manufacturers. Small mines have large sales volume, low price, low debt risk, high cash inflow support, low price and fast recovery cost. Take the 5-ton small excavator as an example, the price of European and American brands is about 360000-370000; The price of Japanese and Korean brands is about 280000-350000; 700000 to 1000000. Under normal circumstances, a small excavator of 1.5~2.0 tons can replace about 6 adults with shovels and trolleys for earthwork. Small excavation is more than 10000 to 1 million. Generally, small excavators of 1.5~2.0 tons can work normally. So,3、 On the advantages of small excavation in modern construction from an objective perspective1. Efficient and deepening urbanization, machine replacing human fieldAs a rising star, small construction machinery has begun to partially replace the position of medium and large machinery in construction, and is widely welcomed by users. With the development of urbanization in depth and breadth in China, roads and users are welcome. With the development of urbanization in China, the maintenance of roads and municipal facilities and the increase of small urban engineering projects, the proportion of its engineering business in the total social construction is increasing. It is estimated that the operation efficiency of a 10-ton small excavator can replace 30 to 50 labor, greatly reducing the construction cost and management cost, and realizing the rising demand for multi-functional small excavators.2. High ROI and versatilitySmall excavation is cheap and cost recovery is fast. Taking the 5-ton small excavator as an example, American and European products can also avoid obstacles without frequent movement of the fuselage. 4、 The market pattern of small excavators in 2017 ≤ 20T Excavators Sales in the first half of 2018 ≤ 20T Excavators Sales in January-December 2018 Slightly cut the sales of some enterprises in January-December 2018, and the sales of some small digging enterprises are large, medium and small The price of 258 brand is about 360000-370000 for Japanese brands; The price of Japanese and Korean brands is about 280000-350000; About 700000 to 1000000. In general, 0 ton of 1.5~2. small excavator can replace about 6 adults with shovels and trolleys for earthwork. Small excavation not only has high work efficiency, but also has low operating costs, and has strong competitiveness in small earthworks. Higher return on investment will lead to more valuable sales. 3、 Objectively, the advantages of small excavation in modern construction operations 1. High efficiency, deepening urbanization process, and small construction machinery in the field of mechanical power generation, as a rising star, have begun to partially replace its position in the construction of large and medium-sized machinery, and are generally welcomed by users. With the deepening and extensive development of urbanization in China, the repair and maintenance of roads and municipal facilities and the addition of small urban projects account for 30 to 50 people in the total social construction, a very high proportion. The earthwork reduces the construction cost and management cost, making the multi-power small excavator popular with the majority of small and medium-sized earthwork construction contractors.3. Strong adaptability to working conditionsThe design and application of the zero rotation radius of the tail allows the small excavator to work calmly in the limited working space environment, and can also prevent damage to the surrounding buildings and the excavator itself. The most important feature of small excavators working in narrow areas is their special boom and stick design. The boom of the small excavator is hinged with the body. It is a large excavator. A large excavator with more than 20 tons can be called a large excavator. It is often used in construction sites, with a flat bottom. Of course, the price is not cheap, at least hundreds of thousands. 2、 According to the movement mode, it can be divided into crawler excavator and wheel excavator: crawler type small excavator is more suitable for poor terrain, potholes, muddy areas, such as field excavation, orchard filling and other scenes. Wheel table small excavator, use the wheel bar to move back and forth, adapt to the problem, and see your position. The better the engine, the better the power, so that the excavator can oscillate in a wide range, so that the excavator can avoid obstacles when there are obstacles around it, without frequent movement of the fuselage.4、 Market pattern of small excavatorSales proportion of ≤ 20T excavator in 2017Sales proportion ≤ 20T excavator in the first half of 2018Sales of some companies increased slightly from January to December 2018From January to December 2018, in recent years, there are more and more small excavators on the market. It has promoted the rapid growth of the number of small projects in China, and the use of small excavators has also increased. Small excavators are widely used. For some narrow spaces, large excavators will be limited by space, but small excavators can operate flexibly and freely. The small excavator has beautiful appearance, high configuration, excellent performance, low fuel consumption, and a wide range of work. Suitable for loosening soil in vegetable greenhouse. The market concentration of small and medium-sized mines is close to the overall market concentration, and the market competition is relatively more intense to dig up the sales volume of some enterprisesComparison of sales volume of large, medium and small minesFrom the perspective of different market models, due to the high technical barriers and market access barriers, the market is more occupied by European, American, Japanese and domestic leading enterprises, resulting in a higher concentration of the domestic large mining market than the small and medium-sized mining market. The market concentration of medium and small mines is close to the overall market concentration, and the market competition is relatively more intense.As an annual event to promote the technological progress of construction machinery and reflect the market demand of construction machinery, the impact is relatively small. The market recovery that began in the second half of 2016 was driven by many factors, among which investment growth was one of the important factors. Therefore, in this round of market recovery, the recovery of medium and large mining machinery market is more significant, and the market share has also increased. In 2018, the domestic sales of excavators reached a record high, but the proportion of small excavation sales was significantly higher than that in the early stage of 2011. Small excavation has the same excavation effect in such large-scale excavation and large excavation. Scale the excavator. The cost includes purchase price and construction cost.On April 2, 2019, the award ceremony of "Top 5 (2019) Annual Products of Construction Machinery" will be held in Beijing. Swing within the scope to make the excavator avoid obstacles without frequent movement) IV. Market structure of small excavators ≤ 20T excavator sales in 2017 accounted for the proportion of ≤ 20T excavator sales in the first half of 2018 ≤ 20T excavator sales accounted for the proportion of micro-excavator sales in January-December 2018 1.1% of the sales of different models of large, medium and small excavators in January-December 2018, a record high market performance, and good news is frequently reported? How to predict future performance? Coming soon!
