How to buy a tractor
1 - Dock tractor: best engine power 266hp low rpm, high torque engine. Moving speed less than 45km / h, tractive weight 60-120tons.
2- Hauling weight less than 35tons on the highway: logistics companies, time is very important. High-speed trucks are your best choice. Because these trucks form better road surface, big engine power is the best choice, like 336hp, 371hp, 420hp. 10 to 16 forward gear aluminum transmission to speed ratio less than 4 single-stage reduction drive axle, choose inner tube and radial for 295 / 80R22.5 or 315 / 80R22.5 tires. The economic speed is 75-105 km/h. There is also the option of adding a deflector, which reduces air resistance and saves fuel.
3- Heavy-duty tractor: tractor weight between 50tons - 7otons: preferably with 420hp engine power, with a larger speed ratio of 4.42 or 4.8 double reduction axle, preferably with 11.00R20 and 12.00R20 tires. economic speed is 72 km/h
4- Super heavy-duty tractor: transporting large cargo and tractor weight over 100tons, super strong frame, engine power 420hp, radial tires, driving speed not more than 55km/h, large transmission speed ratio 5.73, double reduction axle.
5- Extreme road conditions: we recommend trucks with all-wheel drive, like 4x4, 6x6 or even 8x8, 10x10.
