Small excavators are generally equipped with bulldozers. The operator operates the bulldozer pilot handle and controls the main valve through the pilot oil circuit to drive the bulldozer cylinder to work and contract, so as to change the ground clearance of the front edge of the bulldozer. This article will share the various uses of bulldozers.
1. Level the pavement
When the excavator is walking, the bulldozer is placed in the forward direction, and the bottom edge of the bulldozer is flat with the bottom edge of the crawler, which enhances the function of trenching and backfilling. In the process of most operations, the efficiency of the same excavator equipped with bulldozer plate is much higher than that without assembly.
2. The track is suspended and sundries are cleaned
After the excavator works in muddy ponds, concrete and other sticky wetlands, the crawler will be full of mud. At this time, the bulldozer can be put down and supported by large and small arms at the same time, so that the two crawlers can be suspended to facilitate the removal of sundries.
3. Push materials together for easy loading
At the later stage of each work, there will always be a small part of materials that are difficult to dig into the bucket. At this time, the bulldozer can be used to intercept and shovel away the materials in cooperation with the bucket.
4. Stabilized fuselage
When the excavator needs to work on the slope, the bulldozer plate plays the role of stabilizing the body, preventing collapse and slipping, pushing the working surface for backfilling, etc.
5. Convenient for hoisting operation
During the actual operation of excavator, sometimes it is necessary to hoist mixer, cement pipe, etc. Sometimes, the weight of these objects exceeds the weight range that the small excavator can bear, and the center of gravity will shift to the direction of the object to be hoisted, resulting in the swing of the excavator body. At this time, lowering the bulldozer plate can move the center of gravity of the excavator backward, and the operation of the whole machine is more stable.
6. Up and down flat car
Generally, when getting on the truck, the bulldozer plate will be in front to facilitate getting off the truck.
7. Easy to rotate
When the excavator operates in a narrow place, the bulldozer can lean against the edge of the obstacle and take the bulldozer as the boundary. Because the bulldozer plate is wider than the vehicle body, when there are obstacles behind the excavator, the driver can operate the excavator to rotate as long as it does not exceed the position of the bulldozer plate.
