The excavator is a kind of mechanical equipment that can carry out the construction of earth and stone works. It can carry out a variety of engineering operations, such as excavation, transportation and unloading, through different devices. There are many types of excavators, which can be divided into several types according to the use environment and purpose, including wheeled excavators, crawler excavators, small excavators, large excavators, loaders and combined excavators. The following will introduce the knowledge of the excavator in detail.1.Wheeled excavatorWheeled excavators are suitable for working on smooth surfaces.It usually adopts four-wheel drive and four-way steering, has high efficiency, speed and flexibility, and is suitable for road construction, water conservancy projects and urban construction and other engineering projects.2.Crawler excavatorCrawler excavators are generally suitable for work in wilderness and mountainous areas. Because they have better traction and balance, it is more convenient and stable to move over rough terrain and uneven surfaces3.Mini-excavatorMini-excavators are widely used and suitable for projects of various sizes.The size of small excavators is relatively small, but its loading capacity and speed are not lower than other types of excavators.4.Large type (scale) excavatorLarge excavators, also known as heavy excavators, are usually used for large engineering projects, such as mines, tunnels and large foundation projects.5.LoaderLoaders are mechanical devices with large cavities, mainly used for loading and storing materials and earthmoving, suitable for site construction, mining and industrial production. They are generally more flexible, can be moved to different engineering projects, and carry out different material handlingIn short, the excavator is a multi-functional mechanical device, which can be divided into multiple types according to its use and function. The excavator usually has high efficiency, mobility and operational flexibility to meet the needs of different types and sizes of engineering projects. By understanding the different types and characteristics of excavators, users can be helped to choose the most suitable equipment for their engineering project needs.

If your engine isn’t working properly, chances are you’re in for a costly repair. An engine replacement can set you thousands behind. With preventative maintenance, you can keep your car’s engine running smoothly. Your engine is a complex arrangement of electrical systems, complicated mechanical systems, belts, chains and seals, and they all operate under high temperatures to keep you going down the road. Engine Repair.Preventative maintenance is the first step to maintain a resilient engine. When we think of engine failure, timing belts and timing chains are generally what come to mind. Depending on the make of your car, these should be checked every 60,000 miles and again at 100,000 miles.Another sign of engine problems are oil leaks. Oil leaks indicate the need to service your car and can be the result of poor maintenance. When the oil leaks from your engine, the seals are deprived of lubrication and they become dry and brittle. This can lead to fluid loss, and if left unserviced, to catastrophic engine failures. Being attentive about fluid flushes, fuel injection cleanings and routine maintenance are all keys to keeping your car’s engine a happy engine. Like a yearly checkup, your car needs a regular tune-up. Depending on the make and model of your car, the services included in a tune up can differ. For the most part, however, a tune up includes spark plug replacement, spark plug wire inspection, setting the timing belt or timing chain, diagnostic inspection of engine parts and the replacement of air and fuel filters.A car’s engine is a complex machine that relies on the car’s ignition system to start up. Maintaining both your engine and your ignition system ensures your car is healthy.Maintaining your vehicle prevents major catastrophic break downs and repairs in the long run and also keeps your car fuel efficient.

Vodafone, the world's leading telecommunications operator, announced that it has launched commercial 5G networks in 15 cities in Spain. Huawei is a major equipment supplier.The more people suppress me, the stronger I become!You forbid Qualcomm to sell to my chip, I have my own Hisilicon company, and can make better chips in minutes!You forbid Google to let me use the operating system, I have my own Hongmeng system, better than Android!what is this? This is the sigh!When did the excavator industry have such a sigh?But if one day, we don't supply them abroad, and the hydraulic pump can do it!To be honest, the chip is much harder than the hydraulic pump, but Huawei has made it!However, domestic Sany, Xugong, Liugong, and Shanhe are smart, and have not produced domestic high-quality hydraulic pumps!Construction machinery is always closely linked to the development of a country. Transportation, mining, town construction, all infrastructure construction are inseparable from construction machinery, engineering machinery determines the speed of construction of a country, and its development has become One of the important criteria for measuring whether a country's economy is strong.It is undeniable that we have made tremendous progress in the equipment manufacturing industry, but we also have two hard bones in the engine and hydraulic parts. This is the 'lock throat pain' in our equipment manufacturing industry! It should be acknowledged that the overall competitiveness level of China's equipment manufacturing industry still has a large gap compared with developed countries such as the United States.First of all, the high-end manufacturing industry in the United States is almost all of the 'blood' of the United States, whether it is technology, intellectual property or brand. For example, Carter's construction machinery has produced its own products from the engine to the hydraulic parts. The technology of high-end manufacturing in China generally originates from “introduction, digestion, absorption, and innovation”. The technology supply rate of independent innovation is not high. The core technologies and core key components are subject to people, the reliability of products is low, and the high-end of the industry chain is absent.Taking excavators as an example, all but a few well-known excavator manufacturers have occupied a stable position in the individual tonnage market segments, and the remaining mainstream tonnages are almost entirely occupied by foreign brands. Even for domestic excavators, structural parts, electrical components, and cover parts can be purchased domestically. Most of the engine and hydraulic parts are imported from Japan. If the total purchase of a digging machine is 350,000 yuan, the engine wil...

The arrival of summer indicates the begining of the rainy season. In the face of extreme weather, which may lead to natural disasters such as river overflow, flash floods and landslides, what measures should the excavator users do?Today, we has compiled the precautions for the construction and maintenance of the rainy season in the excavator. I hope to help everyone. Rainy season construction considerations1. Pay attention to the surrounding environment before construction, check whether the construction site is soft and trapped. The general method is: use the bamboo poles to poke downwards. If there are many bamboo poles, it will be poked quickly and there is no resistance within 1 meter, indicating that the whole is muddy. The ordinary excavator is very easy to trap and cannot be constructed normally.2. Before the construction of the rainy season in the mountainous area, it is necessary to observe whether there is any possibility of landslides, landslides and mudslides on the mountain. First, observe whether the mountain has broken mountains, whether there are unreasonable excavation, unreasonable spoil, waste slag, quarrying, whether the vegetation grows well, and whether the mountain water is turbid.3. During the construction process, if you feel that the excavator has started to sink, stop the construction in time, find a support point and support the body with the boom to prevent further subsidence. Hurry to drive the excavator back in the same way, do not drive in the other direction. 4, Work in the rain should always be vigilant, night work should maintain the normal work of headlights, work lights, ceiling lights, instrument lights, wipers, etc., to ensure safety.5. After the construction is over, be sure to park the excavator in a safe area with a higher elevation from the place of residence, away from possible danger zones such as landslides and rising rivers, and ensure that the excavator has sufficient oil to start evacuation at any time. Rainy season storage precautions1. If conditions permit, it is best to store the machine in a dry indoor location and thoroughly clean the machine to remove dirt and debris from the machine.2. When parking in the open air, pay attention to check whether the fuel tank and the hydraulic fuel tank cover are tightly closed to avoid unnecessary troubles caused by rainwater seeping into the fuel tank.3. Inspect the machine to repair worn and damaged parts and install new parts if needed.4. Cleaning the main air filter element and lubricate all lubrication points. if possible. Retrac...

The Chinese government’s long-established strategy of using construction projects to boost domestic demand seems to have contributed to better-than-expected quarterly GDP results – and a huge spike in sales of construction machinery.China today reported economic growth of 6.4% for January to March of this year, which was the slowest quarterly figure for 27 years but ahead of analysts’ expectations of between 6.3% and 6.2%.Beijing has sought to head off the effects of weak global growth and the Chinese economy’s growing debt problems by sharply increased domestic investment this year. This has taken the form of tax cuts, infrastructure spending and total bank loans over the quarter of $865bn.Infrastructure spending is expected to grow 4.3% in 2019. This includes $120bn in railway ...
