Zorluk: OrtaWeight Definitions and Limits (GVWR, GCWR, Axle Weights)

A freight dispatcher reviews the scale report for a two-axle straight truck with a manufacturer Gross Vehicle Weight Rating (GVWR) of 26,000 lbs26,000\text{ lbs}, a front Gross Axle Weight Rating (GAWR) of 10,000 lbs10,000\text{ lbs}, and a rear GAWR of 19,000 lbs19,000\text{ lbs}. The certified scale ticket shows the front steer axle carries 9,200 lbs9,200\text{ lbs} and the rear drive axle carries 17,800 lbs17,800\text{ lbs}. Which statement correctly assesses the loading status of this vehicle?

  1. A
    The truck operates legally because total allowable capacity is established by summing the two GAWR values (29,000 lbs29,000\text{ lbs}).
  2. The truck is overloaded because its total gross vehicle weight (27,000 lbs27,000\text{ lbs}) exceeds the plate GVWR (26,000 lbs26,000\text{ lbs}), despite each axle remaining under its GAWR.Cevap
  3. C
    The truck must be evaluated under Gross Combination Weight Rating (GCWR) standards because it operates multiple loaded axles.
  4. D
    The truck operates legally because federal statutory single-axle limits permit up to 20,000 lbs20,000\text{ lbs} per axle regardless of manufacturer plate ratings.

Cevap

The truck is overloaded because its total gross vehicle weight (27,000 lbs27,000\text{ lbs}) exceeds the plate GVWR (26,000 lbs26,000\text{ lbs}), despite each axle remaining under its GAWR.
The Gross Vehicle Weight Rating (GVWR) is the maximum total operating weight specified by the manufacturer for a single unit. Total actual scale weight is 9,200 lbs+17,800 lbs=27,000 lbs9,200\text{ lbs} + 17,800\text{ lbs} = 27,000\text{ lbs}. Because 27,000 lbs27,000\text{ lbs} exceeds the plate GVWR of 26,000 lbs26,000\text{ lbs}, the vehicle is operating overloaded, even though neither individual axle exceeded its GAWR.

Adım Adım Çözüm

1
Calculate the actual Gross Vehicle Weight (GVW) from scale readings.
Actual GVW=9,200 lbs+17,800 lbs=27,000 lbs\text{Actual GVW} = 9,200\text{ lbs} + 17,800\text{ lbs} = 27,000\text{ lbs}.
Gross weight equals the total weight of the vehicle, fuel, and cargo resting on all axles.
2
Evaluate individual axle weights against their respective Gross Axle Weight Ratings (GAWR).
Front axle (9,200 lbs≤10,000 lbs9,200\text{ lbs} \leq 10,000\text{ lbs}) and rear axle (17,800 lbs≤19,000 lbs17,800\text{ lbs} \leq 19,000\text{ lbs}) are both below their individual GAWR limits.
Axles must be checked individually to ensure structural suspension and tire limits are not exceeded.
3
Compare actual GVW against the manufacturer Gross Vehicle Weight Rating (GVWR).
Actual GVW (27,000 lbs27,000\text{ lbs}) exceeds GVWR (26,000 lbs26,000\text{ lbs}) by 1,000 lbs1,000\text{ lbs}.
A vehicle is legally overloaded if either an individual GAWR or the overall GVWR is exceeded.
