在挖掘机的日常操作中，停机时如何处理铲斗是一个需要关注的重要问题。许多操作员在挖掘机停机后会选择将铲斗悬空，而不是将其放置在地面上。然而，这种做法可能会对设备的安全性和长期性能产生影响。本文将探讨挖掘机停机时铲斗悬空的潜在问题，并提供相应的应对措施，帮助操作员更好地维护设备。

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. 铲斗悬空的潜在问题

Potential Issues with a Suspended Bucket

当挖掘机停机时，如果铲斗悬空而不放在地面上，可能会带来一系列的潜在问题。这些问题不仅影响设备的安全性，还可能加速某些部件的磨损，从而缩短设备的使用寿命。

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.

• 液压系统的压力负担：铲斗悬空时，液压系统需要持续承受压力。这可能导致液压油温升高，加速液压部件的磨损。

• 机械结构的应力集中：铲斗悬空会导致挖掘机的臂架和连接部件承受不均匀的应力，增加机械疲劳的风险。

• 安全隐患：铲斗悬空可能在意外情况下突然下落，造成安全事故，特别是在挖掘机处于人员活动密集区域时。

• 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. 应对措施与最佳操作实践

Countermeasures and Best Practices

为了避免铲斗悬空带来的问题，操作员可以采取以下措施，确保挖掘机在停机时处于最佳状态。这些操作实践不仅可以延长设备的使用寿命，还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.

• 将铲斗放置在地面上：每次停机时，操作员应将铲斗完全放置在地面上。这可以减少液压系统和机械结构的压力负担，降低设备的磨损率。

• 定期检查液压系统：即使在遵循最佳实践的情况下，也应定期检查液压系统，确保其处于良好状态，防止潜在故障。

• 操作手册培训：确保操作员接受过专业培训，了解并遵循设备制造商提供的操作手册中关于停机和设备停放的建议。

• 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. 长期维护与设备管理的建议

Recommendations for Long-Term Maintenance and Equipment Management

对于希望最大化设备使用寿命的企业来说，合理的设备管理和维护策略至关重要。除了在停机时正确处理铲斗之外，还有其他一些关键因素需要考虑，以确保挖掘机的长期性能。

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.

• 建立定期维护计划：定期检查和维护挖掘机的关键部件，特别是液压系统、臂架和连接部件。

• 记录设备使用情况：通过记录设备的使用时间、操作条件和维护历史，企业可以更好地预测和预防潜在问题。

• 选择合适的操作条件：在复杂或高应力的操作环境下，适当调整设备的操作方式，以减少不必要的磨损。

• 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.
