在挖掘機的日常操作中，停機時如何處理鏟斗是一個需要關注的重要問題。許多操作員在挖掘機停機后會選擇將鏟斗懸空，而不是將其放置在地面上。然而，這種做法可能會對設備的安全性和長期性能產生影響。本文將探討挖掘機停機時鏟斗懸空的潛在問題，并提供相應的應對措施，幫助操作員更好地維護設備。

In the daily operation of an excavator, handling the bucket when the machine is idle is an important consideration. Many operators choose to leave the bucket suspended rather than placing it on the ground when the excavator is shut down. However, this practice can impact the safety and long-term performance of the equipment. This article explores the potential issues associated with leaving the bucket suspended when the excavator is idle and provides countermeasures to help operators better maintain their machines.

1. 鏟斗懸空的潛在問題

Potential Issues with a Suspended Bucket

當挖掘機停機時，如果鏟斗懸空而不放在地面上，可能會帶來一系列的潛在問題。這些問題不僅影響設備的安全性，還可能加速某些部件的磨損，從而縮短設備的使用壽命。

If the bucket is left suspended when the excavator is shut down, rather than being placed on the ground, it can lead to several potential issues. These problems not only affect the safety of the equipment but can also accelerate wear on certain components, ultimately shortening the machine’s lifespan.

• 液壓系統的壓力負擔：鏟斗懸空時，液壓系統需要持續承受壓力。這可能導致液壓油溫升高，加速液壓部件的磨損。

• 機械結構的應力集中：鏟斗懸空會導致挖掘機的臂架和連接部件承受不均勻的應力，增加機械疲勞的風險。

• 安全隱患：鏟斗懸空可能在意外情況下突然下落，造成安全事故，特別是在挖掘機處于人員活動密集區域時。

• Hydraulic System Pressure Load: When the bucket is suspended, the hydraulic system must maintain pressure continuously. This can cause the hydraulic fluid temperature to rise, accelerating wear on hydraulic components.

• Mechanical Stress Concentration: A suspended bucket can lead to uneven stress on the excavator’s boom and linkage, increasing the risk of mechanical fatigue.

• Safety Hazards: A suspended bucket may suddenly drop in the event of an unexpected failure, posing a safety risk, especially in areas with high personnel activity.

2. 應對措施與最佳操作實踐

Countermeasures and Best Practices

為了避免鏟斗懸空帶來的問題，操作員可以采取以下措施，確保挖掘機在停機時處于最佳狀態。這些操作實踐不僅可以延長設備的使用壽命，還能提升操作的安全性。

To avoid the issues caused by a suspended bucket, operators can take the following measures to ensure the excavator is in the best condition when idle. These best practices can not only extend the lifespan of the equipment but also enhance operational safety.

• 將鏟斗放置在地面上：每次停機時，操作員應將鏟斗完全放置在地面上。這可以減少液壓系統和機械結構的壓力負擔，降低設備的磨損率。

• 定期檢查液壓系統：即使在遵循最佳實踐的情況下，也應定期檢查液壓系統，確保其處于良好狀態，防止潛在故障。

• 操作手冊培訓：確保操作員接受過專業培訓，了解并遵循設備制造商提供的操作手冊中關于停機和設備停放的建議。

• Place the Bucket on the Ground: Operators should always fully lower the bucket to the ground when shutting down the machine. This reduces the pressure load on the hydraulic system and mechanical structure, decreasing the wear rate of the equipment.

• Regularly Inspect the Hydraulic System: Even when following best practices, it’s important to regularly inspect the hydraulic system to ensure it remains in good condition and prevent potential failures.

• Operator Training: Ensure that operators are professionally trained and familiar with the manufacturer’s operating manual, particularly the recommendations regarding shutdown and equipment parking.

3. 長期維護與設備管理的建議

Recommendations for Long-Term Maintenance and Equipment Management

對于希望最大化設備使用壽命的企業來說，合理的設備管理和維護策略至關重要。除了在停機時正確處理鏟斗之外，還有其他一些關鍵因素需要考慮，以確保挖掘機的長期性能。

For companies looking to maximize the lifespan of their equipment, proper equipment management and maintenance strategies are crucial. In addition to correctly handling the bucket when the machine is idle, there are other key factors to consider to ensure the long-term performance of the excavator.

• 建立定期維護計劃：定期檢查和維護挖掘機的關鍵部件，特別是液壓系統、臂架和連接部件。

• 記錄設備使用情況：通過記錄設備的使用時間、操作條件和維護歷史，企業可以更好地預測和預防潛在問題。

• 選擇合適的操作條件：在復雜或高應力的操作環境下，適當調整設備的操作方式，以減少不必要的磨損。

• Establish a Regular Maintenance Schedule: Regularly inspect and maintain key components of the excavator, particularly the hydraulic system, boom, and linkage.

• Keep Track of Equipment Usage: By recording the machine’s operating hours, conditions, and maintenance history, companies can better predict and prevent potential issues.

• Optimize Operating Conditions: In complex or high-stress environments, adjust the operating methods to reduce unnecessary wear.
