Is it not far away that the hottest oil excavator

Is it not far away for the fuel excavator to withdraw from history

is it possible that the great decline of Kodak and Nokia will occur in the excavator industry? Before talking about excavators, let's insert a car:

in September 2017, the automotive industry sent a heavy message. Xin Guobin, Vice Minister of the Ministry of industry and information technology, said at the China automotive industry development forum that some countries have formulated exit schedules for traditional fuel vehicles. At present, the Ministry of industry and information technology has also launched relevant research and will work with relevant departments to formulate China's timetable. At present, Germany, France, the Netherlands, the United Kingdom, India and other countries have proposed a timetable to stop selling fuel vehicles, and the future trend of new energy vehicles is very clear

compared with cars, a small excavator is equivalent to the exhaust emissions of more than 50 household vehicles. Cars have an exit schedule, so the exit schedule of excavators and other fuel engineering machinery is not groundless

with the improvement of environmental protection requirements and the emission standards of fuel engines, especially in 2019, China will begin to implement the National IV emission standards for non road machinery, which will affect the whole construction machinery industry chain. The manufacturing cost of engine manufacturers and engine developers, the service cost of agents and the use cost of end users will increase accordingly

in the face of increasingly demanding emission requirements with better work results and social impact, where should construction machinery go

Dr. long Xiaoping, a visiting professor of Zhejiang University and chief scientist of Hangzhou lanli Electric Technology Co., Ltd. (hereinafter referred to as lanli), gave a choice at the bices2017 Beijing Construction Machinery Exhibition held not long ago: complete electric transformation

Dr. long believes that the improvement of emission standards is actually the greatest support for electric transformation. After country IV, there is country v. if everyone continues to follow the engine, there will be a disaster every 3-4 years. It is a general trend if the electric pipe is dismantled. It is better for everyone to make a homeopathic transformation at this time, create new electric products, and occupy the commanding heights of the future industry

the advantages of electrification are far more than energy conservation and emission reduction. The fuel efficiency of the engine on the excavator is less than 40%, and the remaining 60% is heating, creating harsh working environments such as exhaust gas, noise and vibration. Now, more than half of the so-called core technologies in construction machinery are dealing with the sequelae brought by the engine, and because these inexplicable core technologies occupy a large part of the manufacturing cost and worsen the working environment, many more advanced technologies cannot be used in excavators. Removing the engine is actually removing the obstacles to the progress of excavators to a higher level, such as intelligence and informatization. After the electrification of excavators, there will certainly be a big leap, which is why the upgrading and transformation of excavators should start with electricity

then, how far is the electric excavator from us

Dr. long said that if we follow the traditional technical route, we have to wait until after graphene, but if we change the road, the electric excavator is only one hour or one kilometer away from us

how to understand "1 hour, 1 kilometer"? Dr. long explained that according to lanli's electric scheme, the assembly of electric excavators will not take more than one hour than the assembly of diesel excavators. Excavator operators will not learn electric excavators for more than 1 hour. Loading, unloading and transportation time will not be more than 1 hour. It's just that the customer may hesitate for another hour when choosing

another significance is its applicability: electricity exists everywhere, but not everywhere, all the time. The space blind spot and time blind spot of electricity shall not exceed 1 km and 1 hour. In fact, as long as these two blind spots are solved, the electric excavator can be unimpeded

in the final analysis, the most important thing about the electrification of excavators is the concept transformation, and other problems will change rapidly with the concept transformation. Perhaps, the rapid rise of electric excavators and the rapid decline of fuel excavators are just a thought

from quantitative change to qualitative change, the "road changing" thinking of electrification

as we all know, the electrification of common means of transportation such as electric vehicles and electric buses now is to remove the engine and fuel tank and replace them with batteries and motors. How to improve the energy density of the battery and extend the mileage is the biggest problem. Therefore, the electric vehicle manufacturers are all competing for who can make the electric vehicle run further. There are also many manufacturers of electric excavators that follow the idea of electric vehicles, such as ex02 pure electric excavator, which Volvo just launched this year

however, the daily power consumption of excavators is at least five times more than that of electric vehicles, and excavators cannot run to find charging piles to charge before running out of power, as they do when paying fees on site and issuing invoices to express electric vehicles. If the excavator wants to follow the electrification scheme of the car, it must fall into the mud and cannot climb out. Dr. long believes that the fundamental reason is that the total amount of batteries required by excavators has reached the level of quantitative change to qualitative change

Hangzhou lanli's plan lets us turn 90 degrees to see another scenery. Its original idea is very simple, that is, to use a large power bank to run back and forth between excavator and electricity. If we go back five years, this plan may not be very attractive. But in today's technological and business environment, it is "of extraordinary significance"

According to Dr. long, in terms of product nature, this mobile powered excavator essentially divides the original excavator into two commodities that need to be interdependent and independent of each other. That is, the main machine specializing in the original excavator function and the power supply vehicle specializing in power supply

this practice of lanli also seems to be confirmed by major construction machinery products. As shown in the following figure:

but compared with the above two dual power excavators, lanli's approach is more thorough, completely abandoning the fuel engine. From the perspective of using traditional products, such product reconfiguration actually makes the original products inconvenient. But if we look down from the modern intelligent and information technology platform, it is not a problem to solve this inconvenience at all. From the perspective of sharing economy, the economic benefit of turning the complex and expensive power supply into a universal and shareable independent product is much higher

the actual use time of an excavator is no more than 25%, and 75% of the time is in the sun. If we can share the power supply vehicle with other excavators or other electrical machinery when the excavator is in the sun, the profit rate of the power supply vehicle can be increased by at least twice

it seems very simple to use the power supply truck to supply power to the excavator. Is there any technical content

it is said that lanli is the first enterprise in the world that can send electric excavators to ordinary construction sites for normal work. It certainly needs a lot of technical support to do this. Dr. long said that lanli can not only best separate the excavator from the power supply vehicle in terms of cost and function, but also seamlessly connect it in terms of performance and safety. For example, security. The power of electric excavators is not small, and they use high-voltage electricity. The application environment of excavator is much more complex than that of automobile, and the quality of workers is also very different. How to ensure the safety of electric system under complex conditions? In fact, this is not something that one or two technologies or know-how can solve

excavators are the commanding heights of the electric society

in our common sense, the cost of electric vehicles is certainly much higher than that of fuel vehicles. Without government economic subsidies, it is difficult to have substantial market competitiveness. If you think in this way, excavators need more batteries, and their market competitiveness must be weaker

lanli gives an alternative theory. Dr. long showed us a diagram compiled according to his understanding of the electric adaptability of mobile machinery, as follows:

the horizontal axis represents the mobility of machinery; The essence of electricity is not suitable for moving. The higher the mobility of machinery, the higher the cost

the vertical axis represents the energy consumption of each machine; The biggest benefit of the electrification of mobile machinery lies in the price difference between oil and electricity. If a machine does the same work, the cost of electricity is often only 1/3 of that of oil. The more oil the machine consumes, the higher the benefit it will get from changing it into electricity

if you arrange all the machines in this picture, you will find that household cars are models with high electric costs and low benefits. However, it has a large social aggregate and great social benefits, but the economic benefits of each electric vehicle are not great. On the contrary, excavators are in the position with the lowest cost of electrification and the highest benefits of electrification. In other words, it can also be called the commanding height of the electric society

electric excavators will obtain the specification compliance statement and supporting documents provided by the upstream faster than electric vehicles.

China will begin to implement the National IV emission standard for non road machinery in 2019. And many countries have begun to implement the timetable of banning the use of engines. These are important driving forces for the popularization of electric power

however, Dr. Long's unique feature is that he firmly believes that the popularity of electric excavators will be faster than that of electric vehicles. In the past, the technological progress of construction machinery followed the automotive technology, and now many excavator manufacturers are waiting for it

but electrification is different. On the one hand, as mentioned above, the emission reduction benefits and economic benefits of construction machinery are much higher than those of automobiles. The more important aspect is the difference in risk tolerance between the two. If there are 10million electric vehicles in this society, if 1% of them are broken down on the road, even if the troubleshooting time of each one is only 10 minutes, the whole transportation system and the whole society will be paralyzed. Even if there are 1million electric excavators, 1% of them fail and lie prone, the social impact is basically zero. Moreover, construction and construction machinery are pillar industries along the road, and the positive effect of electric engineering machinery is much higher than that of electric vehicles

many countries have introduced exit schedules for fuel vehicles. It can be predicted that the exit schedule for fuel excavators may not be far away
