Rationalization of a Cane Haulage System
During this season, due to high running costs of the slewing loader,an exercise wascarriedout to compare the slewing loader and the hi-capacity Bell loaders. The slewing loader in use at the time was the model with high lift boom mounted on a Ford 6600, modified with a Brockhouse torque converter. The comparison revealed that, under the conditions obtaining at Mgayi section, the Bell loader was...
