  1.        Axle spacing

 

The axle spacing for an eligible vehicle as measured from the centre of the last dolly axle, or from the centre of the last drive axle when there is no dolly, to the centre of the first trailer axle (see Figure 1 and 2 below) must be no less than the corresponding values in Table 2.

Note: See below for Tables 2, 3 and 4.

Illustration

Illustration

Figure 2 - Last dolly axle to first trailer axle measurement guide

 

  1.        Mass limits for prime movers and single axle dollies

 

For a prime mover towing a single axle dolly, the combined mass on the drive axle group and the dolly axle must be no more than the corresponding value in Table 3.

Note: See below for Tables 2, 3 and 4.

Illustration

  1.        Mass limits for prime movers and tandem axle dollies

 

For a prime mover towing a tandem axle dolly, the combined mass on the drive axle group and the dolly axle group must be no more than the corresponding value in Table 4.

Note: See below for Tables 2, 3 and 4.

  1.        Mass Limit Adjustment

 

  1.       As an alternative means of complying with this schedule, a vehicle that does not comply with the mass tables can calculate the appropriate mass under this section.

 

  1.       If the vehicle’s drive/dolly axle group to trailer axle group distance is equal to or greater than the required drive/dolly axle group to trailer axle group distance in Table 2, there is no mass limit adjustment; or

 

  1.       If the vehicle’s drive/dolly axle group to trailer axle group distance is less than the required drive/dolly axle group to trailer axle group distance in Table 2, the mass of the vehicle combination is reduced by the following amount:
  1.       Subtract the required drive/dolly axle group to trailer axle group distance in Table 2 by the vehicle’s actual drive/dolly axle group to trailer axle group distance; and
  2.       Divide the figure calculated above by 0.3 and round it up to the next whole tonnes.

 

  1.       To determine the total vehicle combination mass:

 

  1.       For a prime mover and low loader trailer, add the sum of the steer axle, dual-drive tandem axle group and trailer axle group mass and subtract the mass limit adjustment from step 4; or
  2.       For a prime mover, dolly and low loader trailer, add the sum of the steer axle, the drive/dolly axle group mass from step 1 and the trailer axle group mass from step 2.
  3.        Then subtract the mass limit adjustment from step 4.

  1.        Condition - Alternative mass limit adjustment

 

  1.       A vehicle that does not comply with Tables 1 to 4 may alternatively calculate conditional axle masses using the steps set out in this section.

 

  1.       Follow Steps 1 and 5 below if the vehicle’s drive/dolly axle group to trailer axle group distance:

 

  1.       is equal to or greater than the required drive/dolly axle group to trailer axle group distance in Table 4, there is no mass limit adjustment; or
  2.       is less than the required drive/dolly axle group to trailer axle group distance in Table 4, the mass of the vehicle combination is reduced by the following amount:

STEP 1: Subtract the required drive/dolly axle group to trailer axle group distance in Table 4 by the vehicle’s actual drive/dolly axle group to trailer axle group distance;

STEP 2:  Divide this figure by 0.3 and round it up to the next whole tonnes.

To determine the total vehicle combination mass:

STEP 3: For a prime mover and low loader trailer, add the sum of the steer axle, dual-drive tandem axle group  and trailer axle group mass and subtract the mass limit adjustment from step 4; or

STEP 4: For a prime mover, dolly and low loader trailer, add the sum of the steer axle, the drive/dolly axle group mass from step 1 and the trailer axle group mass from step 2.

STEP 5:  Then subtract the mass limit adjustment from step 4.
