How to choose a suitable tractor truck?

Trunk logistics, less-than-truckload logistics, building materials, and construction machinery transportation are all inseparable from tractor trucks. How to choose a suitable CNG tractor truck to meet the customer's economical and efficient requirements requires consideration of two major aspects, the power transmission system, and the carrying capacity. And then consider your functional requirements to choose a vehicle that suits you.

• Identify the goods you pull most often.

• Know which road you take most often and your usual speed.

• Do you have any special needs?

Identify the goods you pull most often.

By clarifying the goods you pull most often, you can know whether your vehicle will often be overloaded. For example, the tractor truck that pulls building materials or sand and gravel is very likely to be overloaded, so you must consider the heavy-duty tractor truck. Affecting the vehicle's bearing capacity is reflected in three major aspects: frame, suspension, and bridge. Of course, it is also related to tires, drive shafts, etc., but heavy-duty truck companies will do the corresponding matching, and users can ignore it. Due to the different divisions of product versions of each enterprise, there is no unified boundary for standard load version, heavy load version, and super heavy load version, but the standard load version is roughly below 55 tons, and the heavy load version ranges from 55 to 70 tons or 65 to 90 tons, the range of super heavy load version is greater than 70 tons or greater than 90 tons. The heavy-duty 6x4 tractor truck generally chooses a two-layer beam frame, and the super-heavy version even chooses a three-layer beam frame, such as a large tractor truck.

For the suspension, the standard version of the vehicle can choose the front and rear with fewer leaf springs or air suspension, which is light in weight. Heavy-duty vehicles can choose the front and rear multi-leaf springs, while for super-heavy vehicles, you need to choose a reinforced suspension. Corresponding to different load tonnages, it is necessary to select the front and rear axles and wheel reduction axles of corresponding tonnages. Because different versions of the tractor truck are designed with different load tonnages, and the heavy-duty version is heavier than the standard-loaded version with the same configuration. Therefore, the standard version of the car does heavy work, and the car may have frequent problems. The heavy-duty version of the car pulls the standard load, and the economy and timeliness are relatively poor.

Know which road you take most often and your usual speed.

The road condition of the highway in the plain area is relatively good, with basically no or few slopes, and the common speed of the prime mover is 80-100Km/h. For example, for long-distance running in the central and eastern regions, high-horsepower engines and small-speed ratio bridges can be considered, and the speed and timeliness will be improved. On expressways in hilly areas or mountainous areas, there are many climbing roads, and the speed of the vehicle will be relatively low. For example, in the middle part of the long-distance race and the Yunnan-Guizhou-Sichuan region, you can choose a bridge with high horsepower and a slightly larger speed ratio. For national or provincial roads with more complex road conditions and limited speed, the vehicle speed is generally only 50-70Km/h, and the vehicle needs a certain overload capacity, so it is not recommended to choose a bridge with a small speed ratio, and it is recommended to choose a double-stage bridge.

Specifically, how to choose the parameters of the engine, gearbox, and axle needs to comprehensively consider the road conditions you often travel and the usual vehicle speed. You can refer to the data of the engine's economic speed zone, the highest gear of the gearbox, the climbing gear ratio, and the axle speed ratio. In the past two years, the trend of tractor trucks with high horsepower is more obvious. On the one hand, it is driven by the enterprise, and on the other hand, it is users with high horsepower that can adapt to long-distance transportation, large transportation areas, and complicated road conditions. Dedicated line users and short- and medium-distance transportation users, should choose high-horsepower engines according to their conditions, and should not follow them blindly.

Do you have any special needs?

This part can be considered from the two major aspects of the chassis and cab of the 4x2 tractor truck. For example, the chassis needs to be equipped with daytime running lights, large fuel tanks, large batteries, front protection, etc. to meet convenience, safety, or other special needs. The cab mainly reflects personalization and comfort, such as the addition of luxurious seats, parking radar, large-screen video system, independent air-conditioning system, the non-standard color of cab painting and color registration of cab, etc. These needs can be based on the user's requirements and budget, and choose their appropriate function configuration.
