A wheel tractor scraper is operating on level ground assume no power derating is required for this equipment condition altitude temperature and so on Disregarding traction limitations what is the maximum value of rolling resistance in pounds per ton over which a loaded scraper can maintain a speed of 11 mph use the scraper specifications in table 8.1 and the performance charts in figure 8.8 and 8.9. 150 pounds per ton.

the unit weight of the material being hauled is 3,000lb/bcy, the weight of the load would be 77,400lb(25.8 bcy 3,000lb/bcy). This is greater than the rated load. The effect will be a few more yards per load, but in time, maintenance costs will increase because of overloading the machine. A material having a higher unit weight would aggravate this effect. However. if the machine was operated in lightweight materials, sideboards would be a reasonable consideration.
