Bulldozers are commonly used earthmoving machines that play an important role in construction sites, mines, agriculture, forestry and water conservancy. Many people think that bulldozers don’t have as many actions as excavators and motor graders, and should be very easy to drive. In fact, although the bulldozer is simple to operate, but to cope with the working conditions, the operators still need to master many construction operation skills, let’s learn together.
Tip one:
Slow large load is more efficient than fast light load, bulldozer operation try to maintain a large load. Although the travelling speed is slower, but can reduce the number of round trips, reduce the empty vehicle mileage, the overall calculation both save time and save fuel consumption.
Tip two:
When encountering long bulldozing operations, work in sections from front to back. Starting from the front end, each distance can be stacked full of material can be, so that after pushing a section and then move back a section. This can not only reduce the distance of bulldozer full driving, but also reduce the distance of bulldozer empty return, improve work efficiency to reduce fuel consumption.
Tip three:
Try to avoid material tumbling. Many people think that the material tumbling in front of the bulldozer shovel is very nice to see, and it is the performance of strong bulldozer power. In fact, material tumbling will increase the wear and tear of the shovel, blade and blade angle, and will increase the fuel consumption of the bulldozer. The correct approach is to keep increasing the load to the maximum amount after the shovel cuts in to increase efficiency, and lift the shovel slightly when the load is full and the material is about to tumble.
Tip four:
When bulldozing near the mountain, we must master the principle of ‘high outside and low inside’, i.e., the side near the cliff is higher, and the side near the mountain should be lower, to avoid the bulldozer from accidental danger. To the cliff push off the earth and rocks, the speed should be slow, pay attention to timely deceleration, bulldozer can not push out the edge of the cliff.
Tip five:
When bulldozing in muddy and soft working conditions, the bulldozer is easy to get stuck, so the amount of bulldozing per shovel should not be too large, and try to avoid stopping, shifting, steering and braking on the way, and bulldoze in 2nd gear if necessary. If you encounter a slippery track, you can lift the shovel blade to reduce the amount of bulldozing, if the bulldozer still can’t move forward, then you can hang the reverse gear backward. At this time, do not lift the shovel blade, so as not to bulldoze the front of the force is too large and tilted forward, resulting in the front of the track sinking, the back of the warping. At this time also can not steer, in order to prevent one side of the track force is too large and aggravate the stuck car. Once trapped in the car can not frequently increase the throttle to save themselves, in order to prevent the bulldozer sinks deeper and deeper.
Tip six:
Push the stone buried in the ground, to push from high to low, start with a small throttle, wait until the stone is loose and then increase the throttle to push the stone off. If it is a stone or slag piled up on the ground, push it with the shovel blade close to the ground, and the track should also try to touch the ground to drive. If you are clearing slag in a tunnel or underground hole, you should first clear a path from the edge and then push the slag out of the hole one by one from the edge to the centre.
Tip seven:
If the bulldozer has to wade across a river, it should choose a place where the water flow is more rapid, and try not to cross the river at the slow water flow, because this kind of place has a lot of silt in the riverbed and it is easy to get stuck in the car. The depth of the river can not exceed the bulldozer crankcase dipstick mouth, with a first gear or second gear large throttle quickly across the river, try not to stop or reverse in the middle.
Overall:
Overall, bulldozer operation should master a principle: first gear bulldozing operation; avoid unilateral loading as much as possible, maintain a stable bulldozing force, and reduce the distance travelled by the empty vehicle to a minimum.
