長臂挖掘機

省時 省力 省財富

挖掘機對於工程建設的作用相比不用我多說，大家也都了解的很清楚了，它屬於重工型機械設備，如今更是普遍的采用挖掘機加長臂來進行施工，因為使用它所具備的一些操作性能是很高的，但是在使用過程中一定要多多注意一些細節方麵的問題，接下來為您介紹。

I don't need to say much about the role of excavators in engineering construction. Everyone knows very well that excavators belong to heavy industry machinery and equipment. Nowadays, it is common to use excavators with extended arms for construction, because some of its operational performance is high. However, it is important to pay more attention to some details during use. Next, we will introduce it to you.

由於挖掘機加長臂比標準臂更長更重動作慣性更大，因此，操作時比標準臂要輕，各操縱過程應平穩，動作不宜過快過猛，不宜緊急製動。

Due to the fact that the extended arm of the excavator is longer, heavier, and has greater inertia than the standard arm, the operation should be lighter than the standard arm. Each control process should be smooth, and the action should not be too fast or too strong. Emergency braking is not recommended.

挖鬥容量按出廠標準配置使用，嚴禁更換使用大容量的挖鬥。

The capacity of the excavator bucket should be configured according to the factory standard, and it is strictly prohibited to replace it with a larger capacity excavator bucket.

挖掘機的作業和行走場地應平整堅實，對鬆軟地麵應墊以枕木或墊板，沼澤地區應先作路基處理，或更換濕地專用履帶板。

The operation and walking site of excavators should be flat and solid. Sleepers or pads should be placed on soft ground. In swampy areas, roadbed treatment should be carried out first, or wetland specific track plates should be replaced.

使用前，履帶式挖掘機的驅動輪應置於作業麵的後方。

Before use, the driving wheels of the tracked excavator should be placed behind the working surface.

平整作業場地時，不得用鏟鬥進行橫掃或用鏟鬥對地麵進行夯實。

When leveling the work site, it is not allowed to sweep horizontally with a bucket or compact the ground with a bucket.

挖掘機作業時，除鬆散土壤外，其開挖高度和深度，不應超過機械本身性能規定。反鏟作業時，履帶距工作麵邊緣距離應大於2.0m。

During excavator operation, except for loose soil, the excavation height and depth should not exceed the performance specifications of the machinery itself. During backhoe operations, the distance between the track and the edge of the working surface should be greater than 2.0m.

作業前檢查項目應符合下列要求：照明信號及報警裝置等齊全有效；燃油潤滑油液壓油符合規定；各鉸接部分連接可靠；液壓係統無泄露現象。

The pre homework inspection items should meet the following requirements: lighting signals and alarm devices should be complete and effective; The fuel, lubricating oil, and hydraulic oil meet the regulations; The connection of each hinged part is reliable; There is no leakage in the hydraulic system.

作業時挖掘機應盡量保持水平位置，將行走機構製動住，並將履帶揳緊。

During operation, the excavator should maintain a horizontal position as much as possible, brake the walking mechanism, and tighten the tracks.

遇到較大的堅硬石塊或障礙物時，應待後方可開挖，不得用鏟鬥破碎石塊凍土或用單邊鬥齒硬啃。

When encountering large hard stones or obstacles, excavation can only be carried out after they have been cleared. It is not allowed to use a bucket to break the frozen soil of the stones or to use a single side bucket tooth to gnaw hard.

挖掘懸崖時，應采取防護措施。作業麵不得留有傘沿及鬆動的大石塊，當發現有塌方危險時，應立即處理或將挖掘機撤地帶。

When excavating cliffs, protective measures should be taken. There should be no umbrella edges or loose large stones left on the work surface. When there is a risk of collapse, it should be dealt with immediately or the excavator should be evacuated to a safe area.

作業時應待機身穩定後再挖土，當鏟鬥未離開工作麵時，不得作回轉行走等動作。回轉製動時，應使用回轉製動器，不得用轉向離合器反轉製動。

When doing homework, it is necessary to wait for the machine body to stabilize before digging. When the bucket has not left the working face, it is not allowed to make actions such as turning back and walking. When turning the brake, the turning brake should be used, and the steering clutch should not be used for reverse braking.

顫抖升降不得過猛，下降時，不得碰撞車架或履帶。

Trembling lifting should not be too violent, and when descending, it should not collide with the frame or tracks.

動臂鬥杆在抬高及回轉時，不得碰到洞壁溝槽側麵及其他物體。

When lifting and rotating the boom, it must not touch the side of the tunnel wall groove or other objects.

作業中當液壓缸伸縮將達到極限位時，應動作平穩，不得衝撞極限塊。

When the hydraulic cylinder reaches its limit position during homework, it should move smoothly and not collide with the limit block.

作業中當需製動時，應將變速閥置於低速位置。

When braking is required during homework, the variable speed valve should be placed in the low-speed position.

作業中當發現挖掘力突然變化，應停機檢查，嚴禁在未查明原因前擅自調整分配閥壓力。

When there is a sudden change in excavation force during homework, the machine should be stopped for inspection. It is strictly prohibited to adjust the distribution valve pressure without identifying the cause.

作業中不得打開壓力表開關，切不得將工況選擇閥的操縱手柄放在高速檔位置。

Do not turn on the pressure gauge switch during homework, and do not place the operating handle of the working condition selection valve in the high gear position.
