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
