On October 29, Zhu Xianglei, director of the Data Resource Center of China Automotive Research Center, said at the 2013 China (Suizhou) Special Purpose Vehicle Industry Development International Forum held in Suizhou, Hubei, that the Chinese truck market is gradually warmer than last year, but the import and export data is declining, while truck capacity Excess, the development of new energy trucks needs to be broken.
The domestic truck market is gradually picking up, and the import and export data is falling.
Zhu Xianglei said that from January to September 2013, the cumulative sales of trucks in the domestic market was 2.63 million units, a year-on-year increase of 7.2%, compared with the gradual recovery of the truck market last year.
On the export side, after China joined the WTO in 2001, the truck export market grew rapidly; the 2008 financial crisis led to a sharp decline in truck export growth in 2009, but with the improvement of the international macro environment, the export market gradually recovered.
The specific data is from January to August 2013. China's trucks exported a total of 220,000 vehicles, down 12.3% year-on-year. Due to factors such as the turmoil in the international situation and the rise of trade protection in some countries, exports have declined this year.
On the import side, China's truck import market has a clear cyclicality, with a cycle of four years; due to the increased demand for high-end trucks in recent years, the number of Chinese truck imports in 2010-2012 has remained at a relatively high level.
The specific data is from January to August 2013, the cumulative import of trucks was 0.9 million, down 41.99% year-on-year. Among them, the import volume of heavy trucks above 20t decreased by a large margin, which lowered the overall trend.
Truck overcapacity is close to 50%
Zhu Xianglei said that in 2010, the rapid growth of the auto market ignited the passion of various auto companies to expand production capacity. Major auto companies have issued strategic plans in the 12th and 50th years, increasing investment expansion of their businesses and enabling commercial vehicle production capacity. The scale has expanded rapidly.
He believes that from the current production and demand situation in various market segments, heavy, medium, light and micro-cards are overcapacity. The direct consequence is that the company's capacity utilization rate is insufficient, increasing the operating costs of enterprises, and reducing operating costs. The merger and reorganization is inevitable.
According to reports, the current capacity of domestic medium and heavy trucks is about 2 million, but the actual market demand is only about 1 million;
In 2011, domestic light truck production capacity will be about 2.6 million to 5 million units, and it is expected to reach 4 million to 4.5 million units by 2015, but the actual market demand is about 2 million units;
Micro-cards currently have a domestic production capacity of 100-1.5 million units, but the actual market demand is about 600,000 units.
Natural gas heavy truck sales increased by 300% year-on-year, but new energy trucks need to break ice
Zhu Xianglei said that natural gas heavy trucks, as a new energy truck that emits better than diesel heavy trucks, have developed rapidly in the past two years. In January-August 2013, sales of 23,000 vehicles were sold, nearly three times the year-on-year growth. The annual sales volume is expected to reach 35,000 vehicles. From the perspective of product structure, natural gas heavy trucks are mainly tractors.
Although natural gas heavy trucks have developed rapidly in recent years, they still believe that new energy trucks need to be broken. He said that the prospects of new energy trucks are unknown, and pure electric vehicles are waiting to be broken. Although the state has repeatedly expressed its support for the development of electric vehicles, the construction of supporting facilities such as charging stations is still slow, and it is not enough to meet the needs of trucks as transportation vehicles to charge anytime and anywhere.
At present, the development technology of electric trucks is complicated, the cost is high, and the technology is not perfect. For the trucks used for making money, the market competitiveness is greatly reduced, which is not enough to attract truck users to purchase. Battery cruising range and charging time directly restrict the transportation efficiency of trucks and affect the economic benefits of truck users.
Dump Truck, Tipper is through hydraulic or mechanical lifting and self-unloading cargo vehicles. Also known as dumpers. From the vehicle chassis, hydraulic lifting mechanism, cargo compartment and take power plant and other components.
Scope
Dump Truck in civil engineering work and is often combined with excavators, loaders, conveyor and other construction machinery, constitute loading, transportation and unloading production lines, earthwork, gravel, bulk material handling and transportation work.
working principle
Dump truck engine, chassis and cab of the truck and the general structure of the same.
Dump the car after tipping and lateral tipping points to two types of operating system by control rod movement, backward tipping more common, pushing the piston rod so that the car tipping a few two-way tipping.
High-pressure oil through distribution valves, tubing into the lift cylinder, front-end cab car safety shield.
The engine through the transmission, PTO driven hydraulic pump unit, hydraulic tilting mechanism from the tank car, hydraulic pumps, dispensing valve, hydraulic lifting cylinders, control valves and tubing and other components.
The engine through the transmission, PTO devices driven hydraulic pump, high-pressure oil through distribution valves, tubing into the lift cylinder, push the piston rod so that the car tipping. After the tipping more common, by manipulating the system control movement of the piston rod, the car can stop at any desired position on the slant. Carriage using its own gravity and hydraulic control reset.

advantage
Since the car can automatically load certain tipping angle discharge, saving unloading time and labor, shorten the transport cycle, improve production efficiency, reduce transportation costs, it is a commonly used special transport vehicles.
Care Tips
The new dump truck or car repair factory commissioning must be carried out so that the car ran smoothly without lifting process.
When using the various parts should be required to correct selection of lubricants, saving time and labor unloading, lifting mechanism strict schedule swap oil.
According to the rated load of the shipment, non-overloading.
Practice
1, can not be loaded in the middle of a sudden the elevator lift handle to the "down position."
In the event of this error, the car suddenly rushed down, the frame will bring a great impact, and even accidents. Therefore, we should try to avoid the above operation, if special circumstances also need to be careful, try to slow down the landing speed, the car suddenly do not have to avoid falling in the end.
2, do not mention the use of stronger car - brake suddenly unloading.
Due to fierce mention car inertial force is large (typically 5 to 20 times the rated lifting force), can easily result in permanent deformation of the frame, carriage and pay the frame open welding, burning or destruction of the pump seals, hydraulic cylinders and other damage damage , reduced service life of the vehicle, there will be severe rollover accident. Therefore, the general dump truck while driving ban lifting.
3, after the dump truck to be unloaded disengage the power take off before driving.
If this occurs operational errors, dump truck while driving, because the PTO in the "engaged" position, the lift pump is at "small cycles" state high speed for a long time no-load operation. Cause oil temperature rises rapidly, easily lead to damage to the pump seals, the pump even "burn" phenomenon; more serious is the operation of the pump means that the hydraulic system has a power source, in driving the process prone to auto-liter car since the accident.
4, with the power take off is not available in the "on" position.
If the "on" state (red light lit), the pump will continue to rotate, the hydraulic system there is a power source, so it will because the gas control valve on the steering malfunction caused by automatic car lift; gas at this time distribution valve control even in "down" position, but also into the oil pump, and the pump will burn out.
