When operating a dozer, one should follow a principle: use first gear for pushing soil; try to avoid single-side loading, maintain a stable pushing force, and minimize the distance traveled empty.
1. Slow speed with heavy load is more efficient than fast speed with light load. When operating a dozer, try to keep a heavy load as much as possible. Although the traveling speed is relatively slow, it can reduce the number of round trips and the distance traveled empty, saving both time and fuel in the long run.
2. For long-distance pushing operations, work in sections from front to back. Start from the front end and push each section until it is fully filled with materials. Then move the dozer forward to the next section. This approach can reduce the distance traveled with a full load and the distance traveled empty, improving work efficiency and reducing fuel consumption.
3. Try to avoid material rolling. Many people think that material rolling in front of the dozer blade looks impressive and indicates strong power. In fact, material rolling increases the wear of the blade, cutting edge, and corner, and increases fuel consumption. The correct approach is to continuously increase the load to the maximum after the blade cuts in, to improve work efficiency. When the load is full and the material is about to roll, slightly lift the blade.
4. When pushing soil along a mountain, always follow the principle of "higher on the outside and lower on the inside", meaning the side closer to the cliff should be higher and the side closer to the mountain should be lower, to avoid unexpected dangers. When pushing soil and rocks down a cliff, do it slowly and be ready to decelerate in time. The blade must not extend beyond the edge of the cliff.
5. When pushing soil in muddy and soft conditions, the dozer is prone to getting stuck. Therefore, each push should not be too large. During travel, try to avoid stopping, shifting gears, turning, and braking. Use second gear for pushing if necessary. If the tracks slip, slightly lift the blade to reduce the pushing load. If the dozer still cannot move forward, shift into reverse and back up. At this time, do not lift the blade to prevent excessive force on the front of the dozer and cause the front of the tracks to sink and the rear to lift. Also, do not turn at this time to prevent excessive force on one side of the tracks and aggravate the stuck situation. Once stuck, do not frequently increase the throttle to free yourself, as this may cause the dozer to sink deeper.
6. When pushing stones buried in the ground, push from high to low. Start with a small throttle and increase it when the stones become loose. If pushing stones or stone debris placed on the ground, keep the blade close to the ground and try to keep the tracks in contact with the ground during travel. If clearing stone debris in a tunnel or underground cave, first clear a path along the edge and then gradually push the stones out from the edge to the center.
7. If a dozer needs to cross a river, choose a place with a faster current rather than a slow one, as slow-flowing areas often have more silt and are prone to getting stuck. The depth of the river should not exceed the oil dipstick opening of the crankcase. Use first or second gear with a large throttle to cross the river quickly and avoid stopping or reversing in the middle.Hydraulic Bulldozer
