Product Description:

Adopting 6×4 driving type, equipped with Weichai WP10 series diesel engine with High-pressure & Common rail or EGR ranged from 290PS to 430PS, various models of FAST gearbox, Hande axles and firm frame, Dayun tractor truck CGC4250 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:Heavy truck traction saddle difference, the difference between 50 or 90#, medium and heavy difference
The saddle 5090 of the heavy truck tractor represents the diameter of the work of the traction saddle, followed by the traction pin diameter of the trailer, 50 saddles, 50 traction pins, 90 saddles, and 90 traction pins
Q:Tractors, 6x4 and 6x2, and 4x2. What's the difference between them?
First of all, the semi-trailer driving license is based on self rated load out of semi-trailer carriage recalculation.The 6x4 represents the 6 wheel, the 4 drive wheelsThe 6x2 represents the 6 wheel, the 2 drive wheelsThe 4x2 represents the 4 wheel, the 2 drive wheels
Q:What's the difference between the liberation of J6M and the J6P tractor?
Jiefang J6 is a brand-new commercial vehicle platform developed by FAW independently. It has been developed for three generations after five years of careful training. It has the characteristics of reliability, economy, power, safety and comfort. Since its listing, it has gained extensive market recognition and universal user identification.
Q:Dongfeng dragon 451 horsepower semi-trailer, how much is the headstock?
Jac K3 series of heavy trucks, 336 horsepower 6X2 LNG tractor (HFC4241P1N5C29V) 335 thousand yuanIts configuration is: drive form: 6X2Weichai engine: WP10NG336E50Horsepower: 336 horsepowerTransmission: 12JSD160 Aluminum Alloy FashiteFuel type: DieselEmission standard: country five / Europe five
Q:Is the hang (all - or - half) car behind the tractor capable of driving?
