With the continuous expansion of the heavy truck and light truck markets in recent years, the market share of China Card has been decreasing year by year. According to the data, the market share of China Card in 2004 was 13.38%, which dropped to 12.80% in 2005 and fell to 11.53% again in 2006.
In response to this phenomenon, industry experts pointed out that with the development of China's national economy and with the development trend of international modern logistics, trucks have become an indisputable fact in the development of both heavy-duty and light-weight. Against such a backdrop, the shrinking market share of China Card is also a general trend.
However, from the market performance in 2006, China Card did not decline. Influenced by the macroeconomic environment and favorable policies, from the second half of 2006, the medium- and heavy-duty truck market was just like the stock market at that time, "catch up with a wave of prices": not only has it completely shaken off the shadow of 2005 adjustments, but has also been advancing rapidly. The bull market continues today. Among them, the China Card Market began to rebound significantly in July of last year, and achieved an impressive 51.50% year-on-year increase in sales in October. This is impressive. In the end, the sales of the China Card Market in the first half of last year achieved sales growth of 3.86% year-on-year.
In 2007, will China Card continue to maintain such a market trend, or will it continue to shrink as it follows the trend of polarization? In response, some people in the industry have expressed their views to reporters.
Still seductive cake
For the prospect of the China Card Market, Wang Baoqing, deputy general manager of Jianghuai Automobile Truck Marketing Corporation, expressed optimism. He analyzed with reporters that the shrinkage of the Chinese card market was due in large part to the fact that the major models in the traditional Chinese card market were all upgraded from light trucks, but they were adjusted based on the needs of users in light of the existing light trucks. Strictly speaking, it is not really a middle card. With the rapid development of China's economy and the continuous improvement of road quality, the traditional card cannot meet the needs of the market. What the market needs is a high-quality medium card that can truly meet the needs of users.
In addition, although the trend of the polarization of trucks is in line with the development laws of the developed foreign automobile markets, due to China's huge market and market demand also varies from place to place, China Card still has great market potential. Wang Baoqing further analyzed that a relatively fixed market in China Card is mainly concentrated in economically underdeveloped areas such as townships and rural areas, because the price of heavy trucks and the cost of using them are very high. In contrast, Zhongka has a lot of economic and traffic conditions in many townships. It is not suitable for heavy-duty heavy-duty trucks, so users in these areas often use medium-sized cards instead of heavy trucks.
"China Card Market is still a seductive cake."
This is Wang Baoqing's evaluation of the China Card Market. In the interview, the reporter learned that, in addition to JAC has launched new products in the card, many heavy truck companies also showed the intention to extend the product line to develop the market in the card. A person revealed to reporters that although the market share of China Card has declined, it is partly due to adjustments made by Dongfeng and FAW in the product structure, because the sum of the sales volume of the two cards in the company accounted for Zhongka. Nearly 60% of the market, in fact there is no shortage of markets, many companies are eager to try.
Unique advantages
Compared with light trucks and heavy trucks, China Card has its own advantages and therefore has a stable market. Liu Junli, a truck network analyst, told reporters that the biggest advantage of China Card is its short-to-medium distance transportation. He analyzed that although the large-tonnage light trucks are selling very hot at present, for users with relatively higher capacity requirements, the medium-sized cards with light weight and strong bearing capacity are still their first choice. Statistics show that, in 2006, the cumulative sales volume of 6 tons of total vehicle ≤8 tons models reached 55,522 vehicles, accounting for 40.48% of the market share of the card, an increase of 26.09% year-on-year. It can be seen that Zhongka products with medium tonnage, light weight, relatively high horsepower, and large tires dominated the China Card market last year.
Another characteristic that the card is valued by the user is that it is affordable but has a strong overloading capability and is often used as an alternative to a heavy truck. Although super-advancement efforts have been made and freeway tolls have been imposed on highways, there is still a lack of restrictions on roads outside the expressway. In particular, medium- and short-distance transport between mining areas or engineering construction sites often uses medium-duty trucks with strong overload capacity.
In addition, China Card is very suitable for the transformation of construction machinery vehicles and special vehicles for municipal construction. Liu Junli said that this market has great potential and high profits. Taking the road sweeper as an example, he said that due to the continuous development of urban construction, the city’s demand for road sweepers is increasing day by day, and its functional requirements are getting higher and higher. At present, many municipal special vehicle technologies rely on imports.
From the standpoint of market development advantages, Liu Junli said that the China Card Market has always been the first place for manufacturers who want to enter the heavy truck sector, and will not easily give up the market. At present, the impact of the mandatory automobile standards imposed by the state on the China Card market is far less than that of heavy trucks and light trucks. Even in the short term, it will have a certain role in promoting the demand of the card market. This has also directly led to the weakening of the monopoly effect of the domestic card market in recent years and its stronger competitiveness.
The outlook is not optimistic
Regarding the prospects for the development of the China Card Market in 2007, a relevant person of Shaanxi Automobile said that at least in the long run, it should be cautious. According to the source, the major heavy truck companies currently focus their efforts on the development of overweight tonnages with higher tonnage and more horsepower. How much energy and mind to eat the "leftovers" in the bowl will not be known. From the perspective of last year’s market, the polarization of the truck market accelerated. Although China Card’s growth rate was 3 percentage points year-on-year, its market share remained the smallest among the truck market segments. The lack of market potential has enabled China Card to increase even this year, It will not be great.
In addition, the source said that with the increase in the intensity of governance and the scope of coverage, as well as the improvement of road construction in villages and towns, the use of medium-input cards instead of heavy trucks will eventually be eliminated. At the same time, due to the increase in various cost expenditures such as oil prices and shipping costs, the status of China Card in the township and rural transportation markets and the city's short-distance transport market will be to a certain extent be large-tonnable agricultural vehicles or low-grade, large-tonnage or high-level configurations. Light trucks are replaced.
Judging from the information currently available to reporters, in January of this year, due to the impact of the construction of large-scale projects in various regions, the medium- and heavy-duty truck market continued its good sales at the end of last year, which was much earlier than the sales peak that appeared before the Spring Festival. From this point of view, this year's favorable macroeconomic environment will play a catalytic role in the development of the China Card Market. However, in the long run, with the acceleration of the national economy and the acceleration of the internationalization of the truck market, China Card has been shrinking. How long the market can hold the current "platter" can no longer be worrying.
A ball check valve is a check valve in which the closing member, the movable part to block the flow, is a spherical ball. In some ball Check Valves, the ball is spring-loaded to help keep it shut. For those designs without a spring, reverse flow is required to move the ball toward the seat and create a seal. The interior surface of the main seats of ball check Valves are more or less conically-tapered to guide the ball into the seat and form a positive seal when stopping reverse flow.
Ball check valves are often very small, simple, and cheap. They are commonly used in liquid or gel minipump dispenser spigots, spray devices, some rubber bulbs for pumping air, etc., manual air pumps and some other pumps, and refillable dispensing syringes. Although the balls are most often made of metal, they can be made of other materials, or in some specialized cases out of artificial ruby. High pressure HPLC pumps and similar applications commonly use small inlet and outlet ball check valves with both balls and seats made of artificial ruby, for both hardness and chemical resistance. After prolonged use, such check valves can eventually wear out or the seat can develop a crack, requiring replacement. Therefore, such valves are made to be replaceable, sometimes placed in a small plastic body tightly-fitted inside a metal fitting which can withstand high pressure and which is screwed into the pump head.
There are similar check valves where the disc is not a ball, but some other shape, such as a poppet energized by a spring. Ball check valves should not be confused with Ball Valves, which is a different type of valve in which a ball acts as a controllable rotor to stop or direct flow.
A diaphragm check valve uses a flexing rubber diaphragm positioned to create a normally-closed valve. Pressure on the upstream side must be greater than the pressure on the downstream side by a certain amount, known as the pressure differential, for the check valve to open allowing flow. Once positive pressure stops, the diaphragm automatically flexes back to its original closed position.
A swing check valve or tilting disc check valve is check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow. The seat opening cross-section may be perpendicular to the centerline between the two ports or at an angle. Although swing check valves can come in various sizes, large check valves are often swing check valves. The flapper valve in a flush-toilet mechanism is an example of this type of valve. Tank pressure holding it closed is overcome by manual lift of the flapper. It then remains open until the tank Drains and the flapper falls due to gravity. Another variation of this mechanism is the clapper valve, used in applications such firefighting and fire life safety systems. A hinged gate only remains open in the inflowing direction. The clapper valve often also has a spring that keeps the gate shut when there is no forward pressure. Another example is the backwater valve (for sanitary drainage system) that protects against flooding caused by return flow of sewage waters. Such risk occurs most often in sanitary drainage systems connected to combined sewerage systems and in rainwater drainage systems. It may be caused by intense rainfall, thaw or flood.
A stop-check valve is a check valve with override control to stop flow regardless of flow direction or pressure. In addition to closing in response to backflow or insufficient forward pressure (normal check-valve behavior), it can also be deliberately shut by an external mechanism, thereby preventing any flow regardless of forward pressure.
A lift-check valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps motion of the disc on a vertical line, so the valve can later reseat properly. When the pressure is no longer higher, gravity or higher downstream pressure will cause the disc to lower onto its seat, shutting the valve to stop reverse flow.
An in-line check valve is a check valve similar to the lift check valve. However, this valve generally has a spring that will 'lift' when there is pressure on the upstream side of the valve. The pressure needed on the upstream side of the valve to overcome the spring tension is called the 'cracking pressure'. When the pressure going through the valve goes below the cracking pressure, the spring will close the valve to prevent back-flow in the process.
A duckbill valve is a check valve in which flow proceeds through a soft tube that protrudes into the downstream side. Back-pressure collapses this tube, cutting off flow.
A pneumatic non-return valve.
Multiple check valves can be connected in series. For example, a double check valve is often used as a backflow prevention device to keep potentially contaminated water from siphoning back into municipal water supply lines. There are also double ball check valves in which there are two ball/seat combinations sequentially in the same body to ensure positive leak-tight shutoff when blocking reverse flow; and piston check valves, wafer check valves, and ball-and-cone check valves.
