Product Description:

Adopting 6×4 driving type, equipped with Weichai WP10-WP12 series diesel engine with High-pressure & Common rail ranged from 336PS to 430PS, various models of FAST gearbox, single/double reduction rear axle and firm frame, Dayun lightweight tractor truck CGC4252 achieves 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.

Q:What is the total mass of quasi traction?
The total mass of quasi traction is the theoretical value, also known as the nominal traction tonnage. The total mass of the car and the tractor being towedQuantity is the quality of the car, plus the quality of the traction, the traction on the total quality of consumption, therefore, in the "accounting traction total quality tonnage", not only the quality of the traction as "nominal traction tonnage."
Q:What brand is the best semi-trailer in China?
Made in China, that is, the liberation of heavy duty JAC JAC, Mercedes Benz in the north. The most common is the foreign models and gallop like but do not know the brand of Volvo iveco. This is more common on the highway.
Q:Can the B2 model drive the heavy tractor semitrailer?
Yes, the tractor head is a bike, not a train.
Q:Tractor driving reversing skills?
Tractor reversing skills:When the tractor is reversing, the steering wheel rotates in reverse direction with the reverse direction of the bicycle.Two, sharp bend road conditions, reduce the speed.Three, left bend road, the front side to pull out of the tractor.Four, the right-hand bend road, the inside and back should be close to the central line of the road.Five, in the next reversing, do not impatient, must observe the reverse mirror, looking for good cars sense of distance and direction.
Q:Who knows the price of all kinds of homemade 6 * 6 tractors?
China truck Steyr truck chassis 6x6, protection type, look at the picture, the largest to the Yellow River 10x10 all wheel drive trucks have, you can find your local heavy truck dealers asked with the price, I saw a truck drove full price table, 6x6 truck remember no more than 500 thousand specific, you still consult your local dealer.
Q:How to reverse the tractor. How to pour, how to hit the direction. When reversing, I feel uncomfortable
Before reversing, first adjust the body to do the head and trailer line, reversing the speed can not be too fast
Q:What is the price of a semi-trailer?
So tell you, different semi-trailer brand, their prices are different. Even the same brand of semi-trailer, but different configuration, their prices are different.
Q:What is the axis refers to the truck? Single bridge, double bridge, four after four, eight after the first four, semi-trailer, two up three, three up three: what do you mean?
A revolving part of a machine is mounted on a shaft. Depending on the shape of the shaft, the shaft can be divided into two types: crankshaft and straight shaft. According to the bearing of the axle, it can be divided into: (1) rotating shaft, when it is working, it takes both the bending moment and the torque. It is the most common shaft in the machine, such as shafts in various reducers. The spindle is used to support the rotating parts, only to bear the bending moment, but not to transfer the torque. Some spindles rotate, such as the axle of the railway vehicle, etc. Some spindles do not rotate, such as the shafts of the supporting pulleys. The drive shaft is mainly used to transfer torque and bearing moment, such as the long axis, the automobile crane moving mechanism in the drive shaft. The shaft material is mainly made of carbon or alloy steel, or ductile iron or alloy cast iron. The working capacity of the shaft generally depends on the strength and stiffness, and the high speed also depends on the stability of the vibration.
Q:Which category of the trade mark registration category contains tractors and refitted vehicles?
As for the type of car you want to register, you also need to see the use of your modified car. For example, when you change the car, you can choose the goods: light truck 1202, truck 120076, truck 120022 and so on. Used to do passenger vehicles, you can choose bus 120018, bus 120019, sports car 120178, camping car 120249, RV 120249, and so on. You also need to see what the specific purpose of your car.
