7 Operation Skills of Bulldozer Construction

This is the Bulldozer Supplier introducing you some operational skills in the operation of the bulldozer

Bulldozers are commonly used earth-moving machinery and play an important role in construction sites, mines, agriculture, forestry, and water conservancy. Many people think that driving is very easy, not as complicated as excavators and loaders. In fact, this is not the case. Although bulldozers are simple to operate, they can handle many working conditions.

Therefore, the operator still needs to master many construction operation skills in order to better control the bulldozer and achieve efficient operation.



Technique one

Slow heavy loads are more efficient than fast light loads. Try to maintain a large load when the bulldozer is working. Although the driving speed is relatively slow, it can reduce the number of round trips and reduce the mileage of empty vehicles. Overall, it saves time and fuel consumption.

Technique two

When encountering long-distance bulldozing operations, work in stages from front to back. Starting from the forefront, each distance can be just filled with materials, so after pushing one section, move one section back. This can not only reduce the distance traveled by the bulldozer with full load, but also reduce the return distance of the bulldozer empty, improve work efficiency and reduce fuel consumption.

Technique three

Try to avoid material tumbling. Many people think that the material rolling in front of the bulldozer is very beautiful, which is the performance of the strong power of the Crawler Bulldozer. In fact, material turning will increase the wear of the blade, blade and knife angle, and increase the fuel consumption of the bulldozer. 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, lift the blade slightly.

Technique Four

When bulldozing near the mountain, the principle of “high outside and low inside” must be grasped, that is, the side close to the cliff should be higher and the side close to the mountain should be lower to avoid accidental danger from bulldozers. When pushing and unloading earth and stones down the cliff, the speed should be slow, pay attention to slow down in time, the bulldozer can not push out the edge of the cliff.

Technique 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. Try to avoid stopping, shifting, steering and braking during driving, and use 2 gears when necessary. In case of track slippage, the blade can be properly raised to reduce the amount of bulldozing. If the bulldozer still cannot move forward, it can be reversed.

Do not lift the blade at this time to avoid excessive force on the front of the bulldozer and tilt forward, causing the front of the track to sink and the rear to tilt. It is not allowed to turn at this time to prevent excessive force on one track and aggravate the vehicle trapping. Once the vehicle is stuck, do not frequently increase the throttle for self-rescue to prevent the bulldozer from sinking deeper and deeper.

Technique Six

When pushing a stone buried in the ground, push it from a high place to a low place. At the beginning, use a small throttle, wait until the rock is loose, then increase the throttle to push the rock off. If it is a pile of stones or gravel on the ground, the blade should be close to the ground when pushing, and the crawler should be in contact with the ground as much as possible. If you are cleaning gravel in a tunnel or underground cave, you should first clear a road from the edge, and then push the gravel out of the cave one by one from the edge to the middle.

Technique seven

If the bulldozer is going to cross the river, you should choose a place where the current is relatively turbulent, and try not to cross the river where the current is slow, because the river bed silt in such a place is easy to trap cars. The depth of the river should not exceed the oil gauge opening of the crankcase of the bulldozer. Use the first or second gear to quickly cross the river without stopping or reversing.
