Product Description:

Adopting 4×2 driving type, equipped with Weichai WP10 series diesel engine with High-pressure & Common rail or EGR ranged from 270PS to 375PS and Weichai WP7 series diesel engine, various models of FAST gearbox and  Hande axles, Dayun tractor truck CGC4180 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 difference between single car bridge and double bridge?
The number of driving axles behind is different, and the load of double bridge is relatively largeThe deadweight of single axle freight car is relatively small. More than 2-5 tons of cars, followed by 4 rounds,The load capacity of double bridge is relatively large, which is also commonly referred to as the latter eight rounds,
Q:Can a 2 tonne tractor drag 10 tons of flat cars? Traction is not the same as traction
The 2T of traction should be, and the 20000N of its pull is converted to a mass unit, in other words, its pulling force in the horizontal direction is equivalent to 2T. The weight of the flat car acts in the vertical direction and horizontally pulls it as long as the friction is overcome. If the ground is smooth, the friction may be small and of course it will drag.
Q:The car broke down. How long was the traction rope?
In accordance with the regulations, is greater than 4 meters, less than 10 meters. In practice, the length of the rope is long to find the length of the rope. There is no hard and fast rule. If it is less than 3 meters, the speed must be slow. Don't hit it.
Q:Traction brake system
Hand and foot brakes share a drum brake, no brake master pump and brake pump, few components, reliable performance.
Q:What are the better tractors in China?
Recently saw a super long tiger tractor, looks very domineering.
Q:What kind of dual drive double tractor is it good for semi-trailer?
It's safe to say that the double guide is absolutely unprofessional. If security is why the bus does not use such design, why is this technology not available in commercial vehicle technology leading Europe?.Dual oriented models, if the first four after four, is a policy model. In order to cope with the country in accordance with the number of axes to limit the load of vehicles, such a policy applied to the birth of models only.
Q:What are the differences between trailers and trailer?
In front of the driving ability of the front is called a tractor, there is no traction behind the ability to drive vehicles called trailers, trailers are towed by tractor. There are two kinds of connection mode of the tractor and the trailer: the first one is the front half of a trailer traction saddle in the tractor rear section on the top of the back of the car bridge under traction Trailer part weight, which is half hanging; second is the front end of the tractor trailer even the rear of the towing vehicle only provide forward force, dragging the trailer go, but does not bear the weight down trailer, this is the whole hanging
Q:How to maintain and maintain electric tractor?
Abnormal sound; check the wear of the brush; change the brush as appropriate. 4, check whether the armature rotation is flexible, there is no false wipe phenomenon; check the electrical outlet (or terminal) of the connection is reliable; check all fasteners are fastened; end cover, brush holder must not loose solid. If you want to turn or remove the brush rack, you must mark it properly to loosen the end cap screw. When the brush is reset, align the mark line and tighten the screw so as to keep the brush at the original neutral position. 5 、 brush in the brush grip box should slide freely. The pressure of the constant pressure spring made by the brush shall be normal, and the running area of the brush shall be no less than 80%. The distance from the surface of the brush holder is 2~4mm. 6, check whether the commutators of clean, when necessary, can be soft and lint free cleaning brush commutator of clean cloth and carbon powder on the surface of the commutator groove. If the surface of the oil, white wine can be dipped to wipe (when parking); rough and commutator runout, resulting in uneven surface friction due to brush commutator reached 0.5mm, the car should be light, commutator runout is not greater than 0.04mm, the surface roughness is not greater than 1.6 mu m; commutator insulation shall not be higher than the surface of the commutator, when necessary use planing or milling method, cutting depth is 1mm; the surface of the commutator used for a period of time the pale red, all copper segment of the same color, the surface of the commutator of pale red is a normal phenomenon, copper segment defect is dark.
Q:After the main vehicle and the trailer gas connections are connected, the semitrailer on the tractor shall be unscrewed, and the gas path separation switch shall be connected, so as to know where the switch is located
When the gas connectors are communicated with each other, the semitrailer on the tractor shall be unscrewed, and the gas path shall be connected with the separation switch so as to be in a ventilation state. Otherwise, the gas supply system of the semi-trailer can not be supplied, and the braking system can not work. Three. Start the engine, observe the pressure gauge in the cab, and increase the pressure in the tractor and the semi-trailer cylinder to the required pressure. Four. Check whether the gas path leaks and check whether the brake system works properly. Seven socket cable 5. tractor connection plug is inserted into the front end of the semi-trailer until seven in the clamping block on the bolt. Check whether the electrodes are well joined and make sure that the lights such as the side lights and tail lamps work properly
Q:Are trailers the same as trailers?
Dissimilarity。 A trailer is used for carrying articles inside a carriage. There are two cars available.
