Figure  9-24.—Loading  large  rocks. Figure 9-25.-Bucket positioned for back dragging nonsolid materials. When  loosening  large  rocks  or  other  solid  objects, you can get greater force and penetration by digging under the rock with the bucket, as shown in figure 9-23. Lifting the rock with the bucket while pushing increases traction and reduces track or wheel spinning. When loading large rocks into dump trucks, place a load of dirt or sand into the dump bed. This material acts as a cushioning material and helps protect the dump bed from damage. Then load the large rocks into the center of  the  dump  bed  from  the  lowest  possible  height (fig.  9-24). Figure 9-26.—Bucket clamshell positioned for spreading material. Figure 9-27.—Bucket clamshell positioned for loading trees. NOTE: When  you  have  extended  tasking  to  haul large rocks or riprap, you should have the dump beds lined with wooden planking. This will save time loading sand or dirt and also protect the bed. When  finishing  by  back  dragging  in  nonsolid materials,  position  the  bucket,  as  shown  in  figure  9-25, views A or B. NOTE: Back  dragging  abrasive  materials  causes premature wear to the bucket. By placing the bucket in the scraper position and opening the clamshell slightly, you can spread material on the run. The amount of spread can be controlled by the size of the opening of the clamshell, as shown in figure 9-26. When transporting trees or other large objects, always  balance  the  load,  as  shown  in  figure  9-27. 9-11
