挖掘机加长臂的大特点就是其灵活性和多功能性。它可以根据实际工作需求进行调整，能够在狭小的空间中进行作业，适应各种复杂地形的施工要求。在次坞大桥的建设中，由于地势复杂，挖掘机加长臂的灵活性使得施工更加顺利，能够在狭小的施工空间中进行准确的操作，大大提高了施工效率。而且大桥建设需要进行大量的土方工程和基础设施建设，而挖掘机加长臂正是在这些方面发挥了重要的作用。

The main feature of an excavator with extended arms is its flexibility and versatility. It can be adjusted according to actual work needs and can operate in narrow spaces, adapting to the construction requirements of various complex terrains. In the construction of the Ciwu Bridge, due to the complex terrain, the flexibility of the excavator with extended arms makes the construction smoother, allowing for accurate operations in narrow construction spaces, greatly improving construction efficiency. Moreover, the construction of the bridge requires a large amount of earthwork and infrastructure construction, and the extension arm of the excavator plays an important role in these aspects.

它可以进行土方开挖、石方爆破、基础设施建设等工作，大大减轻了人工劳动的强度，提高了工作效率，挖掘机加长臂的运用使得土方开挖更加快捷、精确，节省了大量的时间和人力成本。

It can carry out earthwork excavation, rock blasting, infrastructure construction and other work, greatly reducing the intensity of manual labor and improving work efficiency. The use of excavators with extended arms makes earthwork excavation faster and more accurate, saving a lot of time and labor costs.

因为施工人员常常需要进行高空作业，存在一定的风险。而挖掘机加长臂的出现，可以将施工人员从高空作业中解放出来，减少了高空作业对施工人员的伤害风险。同时，挖掘机加长臂具有稳定性强、操作简单等特点，大大降低了施工事故的发生概率。

Because construction workers often need to carry out high-altitude operations, there are certain safety risks. The emergence of excavators with extended arms can liberate construction workers from high-altitude operations and reduce the risk of injury to construction workers from high-altitude operations. At the same time, the excavator with extended arms has the characteristics of strong stability and simple operation, greatly reducing the probability of construction accidents.

挖掘机加长臂的灵活性和多功能性使得大桥建设更加顺利，提高了施工效率。同时，它在土方工程和基础设施建设中的运用，减轻了人工劳动的强度，节省了时间和人力成本。此外，挖掘机加长臂的运用还提高了施工的性，降低了施工事故的发生概率。可以说，挖掘机加长臂在大桥建设中发挥了重要的作用，为次坞大桥的建设做出了重要贡献。

The flexibility and versatility of excavators with extended arms make bridge construction smoother and improve construction efficiency. Meanwhile, its application in earthwork and infrastructure construction reduces the intensity of manual labor and saves time and labor costs. In addition, the use of excavators with extended arms also improves construction safety and reduces the probability of construction accidents. It can be said that the excavator extended arm has played an important role in the construction of the bridge and made significant contributions to the construction of the Jiwu Bridge.
