Recently, China (Beijing) International Exhibition on Environmental Protection, Sanitation and Municipal Cleaning EQUIPMENT and Facilities (referred to as “Environmental Protection Exhibitionâ€) was held in Beijing.
The participants of the environmental protection exhibition are mainly sanitation vehicle refitting companies, such as Yantai Hyde, Fujian Longma, Jiangsu Yueda, Zoomlion Heavy Industry, Beijing Tianlutong, Henan Benma, etc. The chassis companies only have Shaanxi Auto Heavy Trucks and Foton Daimler. car. In addition to the traditional environmental sanitation vehicle display, the organizer of the environmental protection exhibition also set up a demonstration area for the city's small advertising and cleaning technology equipment to conduct live demonstrations for the visiting visitors.
Sanitation car emission reduction is the direction
The EPD exhibited more than 50 types of sanitation vehicle models, including compressed garbage transfer vehicles, garbage collection vehicles, kitchen garbage trucks, muck trucks, road sweepers, sprinklers, SNOW shovels, sweepers, and high pressure cleaners. Etc. Among them, the number of sanitation vehicles with Dongfeng chassis is the largest, accounting for 70% of the total.
The author found that the number of natural gas sanitation vehicles has risen sharply. Take Yantai Hyde as an example, among the 13 environmental sanitation vehicles it exhibits, more than half of natural gas vehicles are used. In addition, the diesel sanitation vehicles on display are also equipped with urea tanks, which fully achieve emission reductions.
The audience was very interested in natural gas and pure electric sanitation vehicles. Visitors to the two types of sanitation car booths continued to visit. It is understood that at present, the procurement of new energy sanitation vehicles by the environmental sanitation departments is not large, accounting for about 10% of the total.
New energy vehicle stability to be tested
Mr. Zhang of Tianjin Sanitation System stated: “The sanitation vehicle belongs to professional vehicles. Through the exhibition, we would like to know more about what new technologies are currently available.†He said that the use frequency and route of sanitation vehicles are relatively fixed, so the country now strongly advocates improvement. In the air quality environment, natural gas and pure electric sanitation vehicles can be considered. "The only concern is that these new energy sanitation vehicles will have relatively high failure rates."
From the chassis structure point of view, sanitation vehicles and passenger cars have in common, the battery layout space is larger, the higher the carrying capacity, the battery layout is difficult. The electrification of sanitation vehicles seems to be easier.
Zhang Yitian, regional manager of Beijing Longma sanitation equipment in Beijing, said that sanitation vehicles are basically government procurement. Therefore, from an environmental perspective, the state will increase the support of natural gas and pure electric vehicles.
Degree, through government procurement to promote new energy sanitation vehicles will also do more with less.
New Energy Sanitation Vehicle Subsidy Catalog
In the promotion of sanitation vehicles, the new energy sanitation vehicle has been listed as a national strategy.
The "Notice on Continuing the Promotion and Application of New Energy Vehicles" requires that vehicle procurement in government agencies, public institutions and other fields be tilted toward new energy vehicles, and the proportion of newly added or updated new energy vehicles in bus, official, logistics, and environmental sanitation vehicles. Not less than 30%.
According to the national regulations, subsidies for the promotion and application of pure electric vehicles (mainly postal, logistics, sanitation, etc.) are subsidized: 2,000 yuan per kilowatt-hour for battery capacity, no more than 150,000 per vehicle, and no more than 50 for fuel cells. Ten thousand yuan.
Zhao Jianjun, Assistant General Manager and Head of Sales Department, Henan Benma Co., Ltd.: Urbanization promotes the rapid development of special vehicles
Henan Benma Co., Ltd. exhibited its latest model at the exhibition. Zhao Jianjun, assistant general manager and head of sales department of the company, said that the main product of Benma's participation in this exhibition is the series of pure electric sanitation vehicles, including self-handling garbage collection vehicles, pure electric motor sweepers and dump trucks.
It is understood that Benma Company is part of the Henan Senyuan Group, which had previously mainly produced agricultural vehicles. At present, they have successfully transformed and their product mix has also been adjusted to the new pattern of low-speed cars, medium-light trucks and pickup trucks, and led by special vehicles and electric vehicles.
Zhao Jianjun said that Benma and Senyuan Power Co., Ltd. are fixed-point enterprises that mainly produce special-purpose vehicles, mainly producing engineering and sanitation-type special vehicles. In the past two years, the company has maintained a good momentum of development in the field of special-purpose vehicles.
Speaking of the company's technological superiority, Zhao Jianjun said that Benma has its own technology accumulation in pure electrics, especially in the field of electronic control with its own intellectual property rights. "For the current technological development trend in the field of electric vehicles, domestic companies should develop more technologies with independent intellectual property rights, so that there will be development momentum in the future." He believes.
In the opinion of many people in the industry, there are still scattered and unbalanced developments in the special-purpose vehicle industry in China, and there is room for industrial integration in the future. Zhao Jianjun agreed with this. He believes: "The healthy development of the special-purpose vehicle industry not only requires the efforts of these special vehicle manufacturers, but also requires the guidance and management of relevant government departments."
Speaking of the development of special vehicles, Zhao Jianjun said that with the advancement of urbanization in China, there is still a lot of room for the development of special-purpose vehicles. Benma will continue to make efforts in the areas of new energy electric vehicles, other large and medium-sized equipment, environmental sanitation vehicles, and small advertisement cleaning equipment.
Han Yuan, Project Manager of Shaanxi Heavy Truck Co., Ltd.: New Energy Compression Garbage Truck worthy of promotion
Shaanxi Auto is a veteran trucking company in China. At the exhibition site, Han Yuan, project manager of Shaanxi Heavy Truck Co., Ltd., said that at this exhibition, Shaanxi Auto Heavy Duty Truck exhibited intelligent environmental slag muck, compression-type integrated unloading garbage unloading sanitation vehicles, and natural gas compressed garbage sanitation trucks. Special models.
The new Delong new M30006×4 compression and unloading garbage sanitation vehicle displayed by Shaanxi Auto Heavy Duty Truck is a new type of sanitation vehicle equipped with Shaanxi Auto's new M3000 heavy truck second-class chassis, equipped with air-conditioning and satellite locator driving recorders. . The vehicle has the advantages of realizing volume reduction, sealing, no secondary pollution, reducing the labor intensity of sanitation workers, and improving labor efficiency. "It is more suitable for the collection, compression and transfer of domestic garbage, such as cities, townships, rural areas, large-scale factories and mines, and university living areas." Han Yuan said.
At present, the country vigorously advocates the development of new energy sanitation trucks. Shaanxi Auto Heavy Trucks also exhibited Shaanxi Auto Natural Gas compressed garbage sanitation trucks. Han Yuan said that the vehicle was designed for the new regional environmental-protection vehicle chassis for the characteristics of the regional market, and the emission reached the national V standard. The whole vehicle is made of high-quality high-strength plates. The sides and the top of the car body are rounded and curved, with beautiful appearance and light weight. The optimized sewage diversion mechanism reduces the leakage of garbage trucks. High-strength, oil-resistant nylon material makes for smoother sliding. The three-dimensional model of the vehicle is analyzed and optimized by Hyperworks software, effectively reducing the weight of the filler so that the front-rear axle load distribution reaches 1:3; the two modes “PLC automatic control+manual control†coexist. When the automatic control fails, it can be The use of manual operations is completed without affecting the customer's continued work.
The person in charge of the Beijing Municipal City Environmental Health Association being visited said at the scene that Shaanxi Auto heavy duty truck products have multiple advantages such as environmental protection, energy saving, and reduced operating costs, and developed many new environmental sanitation products suitable for municipal construction.
Yande Haide Dedicated General Motors Co., Ltd. Deputy General Manager Fang Defu: Do not fight price war in the intensive cultivation vehicle market
At the exhibition, Yantai Hyde Special Vehicles Co., Ltd. exhibited 13 vehicles in the five series of pure electric vehicles, natural gas, regular national five, and Chang'an.
According to a participant from the Beijing Sanitation System, Hyde is considered to be a leader in environmental sanitation, and they have purchased a lot of Hyde sanitation vehicles.
“The sales achieved through government procurement accounted for more than 90% of our total sales of sanitation vehicles. The remaining 10% were purchased by some industrial and mining companies. In fact, these companies also bought after seeing the government purchase.†Say.
2000 vehicles and 600 million yuan are figures of government procurement of Yantai Hyde, but Fang Defu is very modest: “This only accounts for 10% of the domestic sanitation vehicle market, and there is still much room for development.â€
As an outstanding company in the sanitation industry, Yantai Hyder often encounters price war projects. Fang Defu thinks this is a painful process, but only for the time being. Currently in the industry reshuffle period, the ultimate survival will only be those who have strength and integrity.
It is understood that in order to get orders, the price of some sanitation vehicles is astonishingly low, and such low prices cannot be profitable at all. Therefore, only good parts and components can be replaced with ordinary ones or even poor ones, which greatly reduces the service life of vehicles. Increased the purchaser's post-maintenance costs.
“In fact, the last damage is the company’s own reputation and brand.†Fang Defu said.
Fang Defu is very confident about his products: “In addition to traditional sanitation models, we have also brought in pure electric and natural gas sanitation vehicles. These models can enter the new energy product catalog and can enjoy subsidies.â€
“We have been working on new energy vehicles for at least half a year earlier than other companies.†Fang Defu believes that if companies want outstanding performance, they must have a forward-looking vision and strategy. “We have early discovered the importance of natural gas vehicles. , so in advance with the gas vehicle chassis supplier cooperation. At that time, their chassis and our car together to make announcements, product promotion greatly ahead of schedule."
Compared with other manufacturers, Yantai Hyde's product differentiation is significant. For example, in terms of miniaturized road garbage sweepers, Hai Germany has the highest market share. “This is because our competitors are mainly foreign brands. Their prices are high, which is generally 980,000 yuan. Our price advantage has been fully reflected.†Fang Defu said that this is very excited.
Hyde will not rush to launch a sanitation car model, nor will it introduce products to customers. "We will do a lot of research in advance," said Fang Defu. For example, the sanitation products in the north and south may not be the same. For example, from energy conservation, which cities are suitable for promoting which cities are not suitable for promotion, these are closely related to the local new energy policy and the environment in which new energy vehicles are used. Enterprises must investigate clearly.
The tandem bicycle or twin is a form of bicycle (occasionally, a tricycle) designed to be ridden by more than one person. The termtandem refers to the seating arrangement (fore to aft, not side by side), not the number of riders. A bike with two riders side by side is called a sociable.
Patents related to tandem bicycles date from the late 1890s.In approximately 1898, Mikael Pedersen developed a two-rider tandem version of his Pedersen bicycle that weighed 24 pounds, and a four-rider, or "quad", that weighed 64 pounds. They were also used in the Second Anglo-Boer War. Tandem popularity began to decline after WWII until a revival started in the late sixties. In the UK The Tandem Club was founded in 1971, new tandems came on to the market from the French companies Lejeune and Gitane, and in the USA Bill McReady founded Santana Cycles in 1976. Modern technology has improved component and frame designs, and many tandems are as well-built as modern high-end road and off-road bikes.
Tandems can have more than 2 riders - tandem refers to the arrangement of the riders one behind the other rather than the number of riders. Bicycles for three, four, or five riders are referred to as "triples" or "triplets", "quads" or "quadruplets", and "quints" or "quintuplets" respectively. One such familiar to UK TV viewers was the "trandem" ridden by The Goodies. Originally a 2-man tandem with an extra "dummy" seat attached, a full 3-man version was built for them by Raleigh.
Some designs such as the DaVinci can allow independent pedaling through the use of multiple freewheels. [4] In another design, the rear rider steers and propels the rear wheel with pedals, and the front rider propels the front wheel with both hands and feet.
