干货！推土机的7个操作技巧！

常用的土石方作业机械，在建筑工地、矿山、农林水利等领域发挥着重要的作用。很多人觉得推土机没有挖掘机和平地机那么多动作，驾驶起来应该非常容易。实则不然，推土机虽然操作简单，但是应对的工况多，操作手们还是需要掌握许多施工操作技巧的，让我们一起来学习一下。

The commonly used earth and stone work machinery plays an important role in the fields of construction sites, mines, agriculture, forestry and water conservancy, etc. Many people think that bulldozers do not have as many actions as excavators and graders, so it should be very easy to drive. In fact, this is not the case. Although the bulldozer is easy to operate, there are many working conditions to deal with, so operators still need to master many construction operation skills,Let's learn together.

技巧一：Skill 1

慢速大负载比快速轻负载效率高，推土机作业时尽量保持大负载。虽然行驶速度比较慢，但可以减少往返次数，减少空车行驶里程，总体算下来既节省时间又节省油耗。

Slow and heavy load is more efficient than fast and light load, and bulldozer should keep heavy load as much as possible during operation. Although the driving speed is relatively slow, it can reduce the number of round trips and the mileage of empty cars, which can save time and fuel consumption in general.

遇到长距离推土作业时，从前往后分段作业。从最前端开始，每段距离恰好可堆满物料即可，这样推完一段再往后移一段。这样既可以减少推土机满载行驶的距离，也可以减少推土机空车返回的距离，提高工作效率减少油耗。

When encountering long-distance soil pushing work, work in sections from front to back. Starting from the front end, each distance can just be filled with materials, so that you can move back after pushing a paragraph. This can not only reduce the driving distance of the bulldozer under full load, but also reduce the return distance of the bulldozer empty car, improve the working efficiency and reduce fuel consumption.

技巧三：Skill 3

尽量避免物料翻滚。很多人认为物料在推土铲前翻滚非常好看，是推土机动力强劲的表现。实际上，物料翻转会增加铲刀、刀片和刀角的磨损，会增大推土机的油耗。正确的做法是铲刀切入后持续增加负载到最大量，以提高工作效率，当负载已满物料将要翻滚时，把铲刀稍微提起。

Avoid material tumbling as much as possible. Many people think that the material rolling in front of the bulldozer is very good-looking, which is the performance of the strong power of the bulldozer. In fact, material turnover will increase the abrasion of shovel blade, blade and blade angle, and increase the fuel consumption of bulldozer. The correct approach is to continuously increase the load to the maximum after the shovel is cut in to improve work efficiency,When the load is full, lift the shovel slightly.

技巧四：Skill 4

傍山推土时一定要掌握“外高内低”的原则，即靠近悬崖那一侧高一些，靠近山体的那一侧要低一些，避免推土机发生意外危险。向悬崖下推卸土石方时，速度要慢，注意及时减速，推土铲不能推出悬崖边沿。

When pushing soil near the mountain, you must master the principle of "high outside and low inside", that is, the side near the cliff should be higher, and the side near the mountain should be lower, so as to avoid unexpected danger of bulldozer. When pushing earthwork under the cliff, the speed should be slow, pay attention to slow down in time, and the Earth shovel cannot push out the edge of the cliff.

技巧五：Skill 5

在泥泞松软的工况推土时，推土机容易陷车，所以每铲推土量不可过大，行驶途中尽量避免停歇、换挡、转向和制动，必要时用2挡推土。如果遇到履带打滑的情况，可适当提升铲刀减少推土量，若推土机仍不能前进，则可挂倒挡后退。此时不要提起铲刀，以免推土机前部受力过大而前倾，致使履带前部下沉，后部翘起。此时也不可转向，以防一侧履带受力过大而加剧陷车。一旦陷车不可频繁加大油门自救，以防推土机越陷越深。

When pushing soil under muddy and soft working conditions, the bulldozer is easy to fall into the car, so the amount of pushing soil for each shovel should not be too large. Try to avoid stopping, shifting gears, steering and braking during driving, and use second gear to push soil if necessary. In case of track slipping, you can properly raise the shovel to reduce the amount of soil pushing. If the bulldozer still can't move forward, you can hang reverse gear back.Don't lift the shovel at this time, in case the front part of the bulldozer is overloaded and tilted forward, causing the front part of the track to sink and the rear part to rise. At this time, it is also not allowed to turn, in case one side of the track is overloaded and aggravates the car. Once the car is trapped, do not frequently increase the throttle self-rescue to prevent the bulldozer from getting deeper and deeper.

技巧六：Skill 6

推埋在地里的石头时，要从高处往低处推，开始的时候用小油门，等到石头松动之后再加大油门把石头推掉。如果是堆放在地面的石块或者石渣，推动时要将铲刀紧贴地面，履带也要尽量接触地面行驶。如果是在隧道或者地下洞中清理石渣，应该先从边缘清理出一条道路，然后从边缘向中间逐次将石渣推出洞外。

When pushing the stone buried in the ground, you should push it from high to low. At the beginning, you should use a small Accelerator. When the stone is loose, you should add a big accelerator to push the stone off. If it is a stone or stone slag piled up on the ground, the shovel knife should be tightly attached to the ground when pushing, and the track should also touch the ground as much as possible. If the stone slag is cleaned in a tunnel or underground hole,A road should be cleared from the edge first, and then the stone slag should be pushed out of the hole one by one from the edge to the middle.

技巧七：Skill 7

推土机如果要涉水过河，应该选择水流比较湍急的地方，尽量不要在水流缓慢处过河，因为这种地方河床淤泥多容易陷车。河水的深度不能超过推土机曲轴箱油尺口，用一档或者二挡大油门快速过河，中间尽量不要停顿或者倒车。

If the bulldozer wants to cross the river by wading, it should choose the place where the water flow is relatively fast, and try not to cross the river at the place where the water flow is slow, because the riverbed silt in this place is easy to fall into the car. The depth of the river water should not exceed the tip of the bulldozer's crankcase. Use the first or second-gear big throttle to quickly cross the river. Try not to pause or reverse the car in the middle.

总体来说，推土机作业时要掌握一个原则：一档推土作业；尽可能避免单边负载，保持稳定的推土力，将空车行驶的距离降到最少。

Generally speaking, one principle should be mastered when the bulldozer works: First gear bulldozer works; Avoid unilateral load as much as possible, maintain stable bulldozer, and minimize the distance of empty cars.
