What is the speed of a tractor unit?

[StellaDella]

Tractor units of different models have varying speeds, with the maximum speed typically around 100 kilometers per hour. More details about tractor units are as follows: 1. Tractor Unit: A tractor unit can have multiple axles according to axle load regulations. The most common types are 4×2, 6×2, and 6×4 configurations. However, some manufacturers offer 6×6, 8×4, 8×6, 8×8, 10×8, and 10×10 axle configurations. The 6×4 has three axles, usually with an undriven front steering axle and two rear axles as driven axles. 6×4 units are more common for long-distance transportation in larger countries like the United States and Australia. In Europe, 4×2 and 6×2 variants are more prevalent. 2. Heavy-Duty Tractor Units: These often have four or more axles and drive more than two axles. In some countries (e.g., Switzerland), a certain weight must be distributed over the driven axles, leading to heavier variants with six-wheel drive; otherwise, an additional tractor unit must be used.
