Product Description:

Adopting 6×2 driving type, equipped with Weichai WP10 series diesel engine with High-pressure & Common rail or EGR ranged from 270PS to 375PS, various models of FAST gearbox and  Pengxiang 457 dual front axle & Hande single/double reduction rear axle, Dayun tractor truck CGC4220 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:Which is better, single drive or double drive?
Dual drive force, suitable for all kinds of road conditions. If the 6 * 2 tractor is near the wheel of the drive wheel, it is easy to gnaw the tire;
Q:FAW J6 semi-trailer tractor 390 horsepower quality, how much oil consumption, how much is the price?
Specific depends on what kind of model you buy, and different models of torque output is different (engine torque is the engine output torque from the crankshaft end. Under the condition of fixed power and engine speed is inversely proportional to the speed, the faster the torque is small, and vice versa. It reflects the load capacity of the automobile within a certain range, with high speed and low speed, high speed and low speed run fast, run slow.)
Q:Which one of the heavy truck traction car is better, horsepower 300-350 between, please prawns specific say
Imported Volvo, Mercedes Benz and other brands of tractors, I will not say, a good word! But often about 1000000 of the price, in addition to units, private is very affordable. So here is to recommend a few heavy tractor made in China is also good, a heavy truck HOWO Howard, FAW, Dongfeng, liberation J6, FOTON AUMAN 336W, Nissan that several heavy tractor are very good, heavy Howard's good reputation, but the car price is high, and there is no use of Weichai engine but, heavy truck independent engine, so the car price is not high, FAW liberation of J5 and the two cars J6 price is very high, the vehicle's appearance is very beautiful, with 350 horsepower diesel engine Wuxi engine, just tin small problems liberated more, no good quality and Weichai, Yuchai cummins. Dongfeng Tianlong car is very good, the appearance is very beautiful atmosphere, with a 340 horsepower DCI engine of Dongfeng Cummins and Dongfeng Cummins engine, features are fuel-efficient, no-load and load, the dynamic performance is very good, especially the DCI engine performance is good, DCI engine is from Renault technology, more fuel-efficient than Cummins Engine moreover, dynamic performance!
Q:There are 6 lines of 340 Auman double drive tractor?
