Question 1388 in the bank

Explain the term “gross axle weight”:

  1. The measured pressure at the tips of the chassis connected springs.
  2. The own weight of each vehicle axle, including the wheels installed on it.
  3. Correct answer: The overall weight of all the wheels installed on one axle against the road.
  4. The own weight of the rear axle that includes the differential system.

Why this is the answer

The correct answer in the official bank: The overall weight of all the wheels installed on one axle against the road.

Gross axle weight is the weight that all the wheels installed on one axle exert together on the road, that is, the part of the weight of the vehicle and its load that rests on that axle. It is not the own weight of the axle and wheels, and not the pressure in the springs. Axle weight limits are meant to protect the road and bridges.
