2 79F Mining Truck 79F Gradeability/Speed/Rimpull * To determine gradeability performance: Read from gross weight down to the percent of total resistance. Total resistance equals actual percent grade plus % for each 0 kg/t (0 lb/ton) of rolling resistance. From this weight-resistance point, read horizontally to the curve with the highest obtainable gear, then down to maximum speed. Usable rimpull will depend upon traction available and weight on drive wheels kg (80,000 lb) GROSS WIGHT lbf x N x lb x kg x % % 000 RIMPU C D D D D D D 0% % 0% % TOTA RSISTANC (Grade plus Rolling Resistance) st Gear mpty nd Gear oaded rd Gear th Gear th Gear Torque Converter Drive Direct Drive

3 79F Mining Truck 79F Standard Retarding Continuous * To determine retarding performance: Add lengths of all downhill segments and, using this total, refer to proper retarding chart. Read from gross weight down to the percent effective grade. ffective grade equals actual % grade minus % for each 0 kg/t (0 lb/ton) of rolling resistance. From this weight-effective grade point, read horizontally to the curve with the highest obtainable gear, then down to maximum descent speed brakes can properly handle without exceeding cooling capacity. The following charts are based on these conditions: C (90 F) ambient temperature, at sea level, with /90R-7 tires. NOT: Select the proper gear to maintain engine rpm at the highest possible level, without overspeeding the engine. If cooling oil overheats, reduce ground speed to allow transmission to shift to the next lower speed range kg (80,000 lb) GROSS WIGHT lb x 000 kg x 000 0% % 0% % 0% % FFCTIV GRAD st Gear mpty nd Gear oaded rd Gear th Gear th Gear

Weights will vary dependent on configuration and may include ± % variation due to standard material tolerances. Calculations include (% OMW) debris allowance. However, actual debris allowance should be considered based upon known site conditions. It is recommended to work with your Global Mining representative to calculate target payload per specific site. Caterpillar recommends the customer evaluate all job conditions and consult the Cat dealer and tire manufacturer for proper tire selection. Reference tire limitations with your local tire distributor concerning details of the tires being considered. Productive capabilities of the 79F are such that, under certain job conditions, TKPH (TMPH) capabilities of standard or optional tires could be exceeded and, therefore, limit production.
