two. Tandem Axle: The most widespread configuration for semi-trucks is a tandem axle set up. This implies the tractor has two rear axles, with every axle getting two wheels. The tandem axle setup presents improved load-carrying capability, China alxe supplier enhanced security, and superior bodyweight distribution.

Regulations may perhaps fluctuate among locations, states, or international locations, so the allowable quantity of axles and pounds distribution may well differ accordingly. Compliance with these regulations is important for safe and lawful procedure of semi-vans on the road.
