A 300 HP crawler tractor is pulling a wagon of 25 cu yd capacity equipped with highpressure tires. The weights of the crawler tractor and the empty wagon are 25 tonsand 15 tons respectively. The haul road is well maintained and compacted earth.Select highest figure in range for rolling resistance. The coefficient of traction is0.75. Half of the weight of the crawler tractor and half of the weight of the loadedwagon need to be considered in the slippage check. No penetration occurs as thesurface is hard enough. The average temperature and barometric pressure at thesite location are 30oC and 56.00 cm of Hg respectively. The drawbarpull producedby the tractor at standard conditions is given in the machine’s manual as 15,000 kgin first gear. What is the gradability of the tractor/wagon combination if the wagon isloaded with dry earth? Take a gradability safety factor of 85%.
