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
For example, half of the car weight of 8 tons, then the driving permit written on the rated load is 32 tons.Because the maximum traction of any type of tractor is 40 tons.Therefore, the 2 axle 4X2 tractor and the 3 shaft 6X4 traction vehicle should be drawn within 40 tons.
Most tractors in developed countries are 4X2 with 2 axles. The semi-trailer is the 3 axle and has 4 axles. Therefore, the total weight of the semi-trailer and the cargo shall not exceed 40 tons.Tractor maximum traction total mass is 40 tons for the tractor is put fine timber to petty use 6X4.The highway toll is calculated by the axle, and the total weight of the 6X4 tractor and the 3 axle semi-trailer shall not exceed 55 tons.6X4 traction truck weighing 10 tons, 3 axle semi-trailer weight 8 tons, vehicle weight of 18 tons, you can load 37 tons of goods.But the driving license is written on the rated load of 32 tons, if the driving license to determine overloading, loading 36 tons is also overloaded.Judging by the driving license, the standard of overloading is much lower than the criterion of overloading by axle.
