Product Description:

Adopting with 6x4 driving type,equipped with Weichai WP12 series gas engine with 350PS/380PS, FAST gearbox and Hande axle, Dayun CNG tractor truck CGC4253 arrives domestic first-class level and also enjoys comfort of Euro-type cab.

1、European driving cab
The European large cab is ergonomically designed and comfortable. It enables the cab to bear over 50% impact by means of
adopting all-metal frame, bird's nest structure design, domestic pioneering energy-absorbing bumper and four-point suspension structure. The designs all enable the cab’s safety and comfort.

2、Spacious and comfortable sleeper design
Spacious sleeper in the cab and thickened sleeper pad enable the cab to be more comfortable for rest. Good sleeper fabric
texture makes it more dirt resistant and durable. The fixing structure of upper bunk becomes more reasonable, the sleeper support and safety protection device are increased and the fixed mode of the sleeper sunshade is also improved.

3、Multi-bit precise-controlled instrument panel
An adjustable LED five-level circulation background lamp is used. The indicator indicates precise reading and self-testing
can guarantee smooth operation.

4、Automatic Cruise Control System
The user can freely set driving speed and keep driving at fixed speed. The intelligent setting can reduce oil consumption
and enhance driving stability.

1、Weichai Power
Weichai engine is designed with the new bypass valve pressurizer, to improve the working efficiency under low speed. The
new engine can increase the low-speed torque by about 12% and reduce the oil consumption by 10%-15% with the oil calibration of the oil spraying pump in the low-speed area. Weichai engine has reliable quality and long lifetime, which make driving more comfortable in effective and economical way.

2、Hande axle
Shaanxi Hande axles are fully optimized. The axle housing is completely thickened and its work section height is increased.
A new quenching technology is applied to the whole half housing, so the whole bending-resistance capability of the driving axle is improved by about 30%. The new quenching technology can enhance gear strength and eliminate possible gear collision.

3、Fast gearbox
Equipped with the heavy automobile transmission which applied American Eaton technology from Shaanxi Fast. Its novel and
advanced design eases gear switching and also improves the bearing capability which is more stable than its predecessor.

4、Drive shaft with Benz technology
The optimized Benz commercial car drive shaft improves the gear shape of the spline and strengthens the gear root. The
sliding fork is upgraded and improved. The spline shaft is optimized to match the spline cover. The new end gear drive improves bearing on the connection flange. The new nylon painting technology improves the bearing status of the working drive shaft, reduces drive impact and completely reduces internal wearing loss.

Dayun automobile is equipped with the equal-work section and high-break work section twist-resisting and bending-resisting frame. The bending-resisting capability of the truck’s longitudinal beam and round girder is also strengthened by using the Stery technology.

- Inquire about price/MOQ

Q:Is there any change in the payload quality of the tractor in the new traffic law?
After the introduction of the new traffic law, the provinces have introduced relevant interpretation of the rules, the actual operation of each province is not the same. The cost of buying a car how to get six figures, it is considered a lot of money, or recommend you to be on the safe side, consult the local traffic management department.
Q:Why is the semi-trailer's carriage and carriage brand different? Does the semi trailer have two pairs of license plates?
Semi trailers have two pairs of plates. The front of the car is the license plate of the car. The car is the number plate of the car.
Q:Can the B2 model drive the heavy tractor semitrailer?
Yes, the tractor head is a bike, not a train.
Q:How many tons are heavy duty semi traction tractors allowed to load?
2 floor of the right, the approved load is not calculated by the shaft, the rear bridge can be installed
Q:Which one of the heavy truck traction car is better, horsepower 300-350 between, please prawns specific say
Not expensive, about 500 thousand, and imported cars, services than imported vehicles in place, mainly parts and components supply in place, after all, in the country.
Q:Matching requirements for tractors and semi trailers
Traction pin size, 90 pin and 50 pin, because domestic or pull more, so a large part of the distribution are 90 pin.At the same time, the traction pin is also separately packed and welded, and the ones over there in Liangshan are all welded directly because of the low priceBut the future is not replaceable. Assembly type, can be replaced after wearing of pin head.
Q:Which is the main drive of the dual drive tractor?
The same power, the greater the output torque, the better. The differential speed ratio is also different (the gear ratio of the main reducer in the automobile drive axle). I'm here to tell you something about overloading. I hope it will help you. Our daily life is more than 100 tons, with 9 speed transmission (12 speed slightly higher prices, mainly we pull goods speed is wasted, at 45--50km/h. 12 speeds is too high, easy to burst with the feeling of J6) overall economy, long service life, not bad. Repair cost is more expensive, we began a liberation from the J5 and the amount of F2000 was ourway, Williams than that J5P Aowei really is a good impress, two years Williams F2000 while using he is in need of repair, the problem constantly.. J6 is also used Aowei engine but it uses more advanced N series. It's OK to use it. It may be different from the usage in every region. See what cars are driving what car, we mainly buy J6350P, and J6, 370P. Dual drive stability, but the bend is not so flexible, there is a forward force, because the double drive wheel and steering wheel distance into a certain centrifugal force.
Q:What is commonly referred to as a tractor is a back bridge or a half bridge? What does it mean?!
A tractor is a vehicle that separates parts of a vehicle from a freight car. Such as Transformers Optimus Prime, that is tractor, and only the front, no cargo box, freight car half of the train skin that kind of super.
Q:now, What kind of tractor is it?
Tractor, a car produced by the Federal Republic of Germany, and these two (6 x 6) tractors were developed on the basis of Ivico Mcgirus off-road vehicles.
Q:What about the red crag and lion tractor?
Good stability, safe and reliable. In many people's eyes, light means insecurity. Well, not really. The lions light tractor is much lighter than other tractors, but its safety is very good. The reason is the lightweight rail tractor Jieshi frame adopts high strength low carbon alloy steel, and the frame has the advantages of light weight, anti distortion and anti impact ability is very strong, greatly improve the driving safety; the cab adopts full steel structure, not easy deformation, high safety coefficient; the car is also used for V cross pin type thrust rod, to prevent the rear axle around the shift, the vehicle stability is very good; the configuration of the shock absorber seat, improved the suspension system of the vehicle, the driver driving a little bumpy. Also, as the overall configuration of the lion is very high, the reliability of the vehicle is very good. Therefore, driving the lion light tractor is very smooth and reliable.
