The details of the speeches made by officials of the Ministry of Industry and Information Technology are as follows: “Some countries have already established timetables for stopping the production and sales of conventional energy vehicles. The Ministry of Industry and Information Technology has also started related research and will also formulate a timetable for China with related departments. These measures will surely promote our country. The environment and power for the development of the automotive industry has undergone profound changes." Therefore, the Ministry of Industry and Information Technology only “initiated related research†and neither pointed out when the timetable would be introduced nor revealed any specific implementation measures. Secondly, the term is “traditional energy vehicles†instead of “fuel vehiclesâ€, and the two are not completely identical in content. Moreover, some degree of China is "inspired" by other countries, but it is clear that the national conditions of different countries are different, and their starting point and purpose are also different. Many of the discussions in the industry today have more or less overlooked these key points. Dong Yang, executive vice president of the China Association of Automobile Manufacturers, put forward different views on the "fuel sales ban." In a recent article entitled "The Internal Combustion Engine Has Not Obsolete", he pointed out that "the prohibition of sales of fuel vehicles" is a misunderstanding. Electric vehicles are still in the stage of catching up with fuel vehicles, and have not reached the level that fully exceeds the number of fuel vehicles in the future. Within ten years, it will be the phase of coexistence of motor drive and internal combustion engine drive. He also said that the internal combustion engine will not only continue to exist, but also the internal combustion engine technology will further develop. Regarding the "timetable" proposed by other countries, there are various versions of itself. It is understood that nine countries or regions, including the Netherlands, Norway, Belgium, Sweden, India, Germany, France, the United Kingdom, and the United States, have identified or are planning to launch a timetable for the ban on the sale of fuel vehicles, but whether the position of each country is true and whether Accurate and questionable. First, the timetable for each country varies from 2025 to 2040. Second, countries are not completely "forbidding" fuel vehicles in terms of expression, but have reservations. For example, the Netherlands stated that it will “take the first step in the prohibition of the sale of conventional vehicles and diesel vehicles in 2025â€, while India stated that “towards a pure electric vehicle countryâ€, California, USA stated that “the sale of traditional fuel vehicles on the market may be banned in 2030. ". By contrast, only the UK’s timetable was proposed by the government’s publicly-developed text, but its statement is simply “the 2040 year’s determination to make every new car ultra-low emissionâ€. In other words, no country has explicitly banned fuel vehicles in the form of laws. It is more about expressing an attitude and remarks. Compared with countries such as Norway and the Netherlands where the automotive industry has a small foundation and the vehicle ownership is not large, compared with the radical attitude of preparing to ban the sale of fuel vehicles in 2025, Germany, France, and the United Kingdom have adopted policies concerning big auto industry countries. Car giant opposition. Take Germany as an example. At the Frankfurt Auto Show held in Germany recently, heads of major German car companies made clear opposition. Volkswagen CEO Müller said that "for a long time to come, traditional fuel vehicles and new energy vehicles will coexist." He further analyzed that the topic of the ban on the sale of fuel vehicles was related to the forthcoming general election in Germany, and that the ban on the sale of conventional internal combustion engine cars after the election would be quelled. If Britain, France, Germany, and other countries propose to ban the sale of fuel vehicles, which are plagued with political attitudes, then there is no need for China to follow suit. This is the view of some people in the industry, but China has its own intentions. Chen Qingtai, chairman of the China Electric Vehicles Centennial Association, believes that the timetable for the ban on the sale of fuel vehicles is not important. What matters is the reason behind this. "The proposed timetable is an incentive for pure electric vehicle companies. It is a relentless force for traditional fuel vehicle companies. It will ultimately benefit everyone." The Ministry of Industry and Information Technology officials said in their speeches: “Many countries have adjusted their development strategies one after another, and the new energy and intelligent network industry have accelerated their industrial layout and seized a new round of commanding heights. After years of hard work, China’s automobile industry has formed a relatively complete industrial system. The technological level in these areas is not much different from that in foreign countries, and it already has the technology and conditions to compete with foreign developed countries on the same stage.†In other words, besides the consideration of environmental protection pressure, China considers more to enhance the overall automotive industry. Competitiveness. China is the world leader in the development of new energy vehicles. Currently, it has promoted more than 1 million vehicles and occupied 50% of the world. The timetable for development is actually driving the development of new energy vehicles. For the same purpose, China has already started issuing "restrictions" on fuel vehicles. In July this year, the State Council made the decision to “in principle no longer approve the construction of a new traditional fuel vehicle production enterpriseâ€. At present, most of the discussions in the industry on the ban on the sale of fuel trucks are based on the recognition that they will be launched soon. However, it is still unknown whether this timetable will eventually come out. On September 27, the Ministry of Industry and Information Technology (MIIT) website officially announced that it had officially passed the "Measures for the concurrent management of the average fuel consumption of enterprises and new energy vehicle points," namely the "double-integration" policy, which will be implemented on April 1, 2018. This is more than in the industry. The reason for the delay in the forecast is precisely because domestic auto makers are not ready yet.
Gantry crane bridge crane is a kind of deformation, also called gantry crane. Mainly used in Outdoor Yard, loading and unloading of goods, the bulk of the field. Its metal structure as a door shaped frame, bearing girder installation of two legs can be directly in the ground track walk, at both ends of a main beam can with cantilever beam. Gantry crane has the space utilization rate is high, and large working range, adapt to wide, general characteristics, widely used in port yard.

Formal classification
Gantry crane can be according to the structure of the door frame, according to the main beam form, according to the main beam structure, according to the use of the form of classification.
Door frame structure
Door type crane and cantilever gantry crane
Portal crane
1. the whole gantry crane: the main beam without suspension, the car in the main span of the;
2. half gantry crane: the legs are high or low, can be used in accordance with the requirements of the use of the site.
Cantilever gantry crane
1. double cantilever gantry crane: the most common form of structure, the structure of the force and the effective use of the site area are reasonable.
2. single cantilever gantry crane: the structure of the form is often due to the restrictions of the site was chosen.
Main beam form
1. single girder
Single girder gantry crane has the advantages of simple structure, convenient manufacture and installation, its quality is small, the partial rail box frame structure. Compared with the double girder gantry crane, the overall stiffness is weaker. Therefore, when the weight is Q = 50t, S = 35m span, can use this form. L type and C type two forms of single girder gantry crane legs. L type of manufacture and installation is convenient, the situation is good, its own quality is small, however, the lifting of cargo through the supporting legs of the space is relatively small number of. The C shaped support legs are bent or bent, and the purpose is to have a larger transverse space so as to enable the goods to pass through the supporting legs.
2. double girder
Strong ability of bearing double girder gantry crane, span is big, the overall stability is good, many varieties, but its quality with the same play weight of single girder gantry crane compared to larger, the construction cost is also high. According to the different structure of the main beam, it can be divided into two types of box girder and truss. Generally use box structure. [1]
Main beam structure
1. truss beam
Structure using I-steel welded together, has the advantages of low cost, light weight, good wind resistance. However, due to the defects of the welding point and the truss, the truss beam has large deflection, small rigidity, low reliability, and so on. Applicable to the safety requirements of the lower, the smaller the weight of the site.
2. Box Girder
The use of welded steel box type structure, has the advantages of high safety, rigidity etc.. Generally used for large tonnage and large tonnage gantry crane. Such as the MGhz1200, the weight of 1200 tons, is the largest gantry crane, main girder with box girder structure. At the same time, the box beam has the disadvantages of high cost, great self important, poor wind resistance and so on.
3. cellular beam
Generally refers to the isosceles triangle honeycomb beam, the beam end is a triangle, on both sides of the diagonal with honeycomb holes, the upper part and the lower part of a chord. The cellular beam absorbs the characteristics of the truss beam and box girder, which has larger stiffness, smaller deflection and higher reliability than the truss beam. But because of the use of steel plate welding, the weight and cost ratio of truss beam Shaogao. Suitable for use in frequent or high weight field or beam field. Because of this type of beam type for patent products, so manufacturers less.
Use form
1. ordinary Longmen crane
This kind of crane adopts box type and truss structure, the most widely used. Can carry a variety of pieces of goods and bulk materials, the weight of 100 tons, the span of 4 to 39 meters. With ordinary high-level gantry crane Grab. General gantry crane is mainly refers to the hook, grab, electromagnetic, gourd gantry crane, which also includes semi gantry crane.
2. hydropower station Longmen crane
Mainly used for lifting and opening and closing the gate, but also to carry out the installation work. Up from 80 to 500 tons, the span is smaller, is 8 to 16 meters; the lifting speed is low, for 1 ~ 5 m / min. Although this crane is not a regular crane, but once the use of the work is very heavy, so to increase the level of work properly.
3. shipbuilding Longmen crane
Ship to berth assembly, standing with two lifting trolley: A has two main hook, running on a bridge on the flange of the track on; and another has a main hook and a pair of hook, run on the flange of the rail of the bridge to turn and lifting of large hull block. Lifting weight is generally 100 to 1500 tons; span of 185 meters; lifting speed of 2 ~ 15 m / min, and 0.1 to 0.5 m / min of the micro motion speed.
4. container crane in Longmen
For container terminals. Trailer bridge to quay container carrying containers unloaded from the ship
Transported to the yard or rear, carried away by the container gantry crane duima up or direct loading, accelerate the turnover of the bridge or other crane container carrying. Can be stacked high 3 to 4 layers, 6 rows of the container yard, the general use of the tire type, but also useful. Compared with the container truck, Longmen crane span and the height of both sides of the gantry are larger. In order to meet the need of the transportation of the port and wharf, the working level of this kind of crane is higher. From the lifting speed is 8 ~ 10 m / points; span across the container as needed to determine the number of rows, up to a maximum of 60 meters corresponding to 20 feet, 30 feet, 40 feet container weight were approximately 20 tons, 25 tons and 30 tons.

The "fuel car banned sales schedule" taken out of context
“The schedule for the ban on the sale of fuel trucks†sparked a wave of waves, among which were the sounds of sing-down fuel trucks. It seemed that the end of the fuel trucks would come at any time. However, things may not be as serious as the public opinion.
