    Non-Divisible Load (Non-Reducible)

    A non-divisible load or vehicle for the purposes of weight calculations is a load or vehicle that consists of a single item, that is usually large and heavy such as a piece of construction, industrial, or structural equipment or machinery.

Under the Code of Federal Regulations non-divisible means any load or vehicle exceeding applicable length or weight limits which, if separated into smaller loads or vehicles would:

  • Compromise the intended use of the vehicle, i.e., make it unable to perform the function for which it was intended;
  • Destroy the value of the load or vehicle, i.e., make it unusable for its intended purpose;
  • Require more than eight work hours to dismantle using appropriate equipment. The applicant for a non-divisible load permit has the burden of proof as to the number of work hours required to dismantle the load.
Loads qualifying as single item non-divisible may be allowed, by permit, to operate with increased axle and axle group weights based on formulas shown on Permit Weight Tables 3 and 4.

For calculating weights for single item non-divisible loads make sure the proper selection has been made on the Entry screen.

Note: Under OAR 734-082-0010 (2) By permit, unladen self-propelled or towed fixed-load vehicles, equipped with low pressure flotation tires (15-inch or larger) shall be permitted 700 pounds per inch of tire width to a maximum of 36,000 pounds on any single axle or 43,000 pounds on any tandem axle.

The weight analysis program will not reflect the allowance for a single axle over 21,500 pounds if equipped with low pressure flotation tires. Call OD Permits for additional information at 503-373-0000.
