挖掘機加長臂的大特點就是其靈活性和多功能性。它可以根據實際工作需求進行調整，能夠在狹小的空間中進行作業，適應各種復雜地形的施工要求。在次塢大橋的建設中，由于地勢復雜，挖掘機加長臂的靈活性使得施工更加順利，能夠在狹小的施工空間中進行準確的操作，大大提高了施工效率。而且大橋建設需要進行大量的土方工程和基礎設施建設，而挖掘機加長臂正是在這些方面發揮了重要的作用。

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.

它可以進行土方開挖、石方爆破、基礎設施建設等工作，大大減輕了人工勞動的強度，提高了工作效率，挖掘機加長臂的運用使得土方開挖更加快捷、精確，節省了大量的時間和人力成本。

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.

因為施工人員常常需要進行高空作業，存在一定的風險。而挖掘機加長臂的出現，可以將施工人員從高空作業中解放出來，減少了高空作業對施工人員的傷害風險。同時，挖掘機加長臂具有穩定性強、操作簡單等特點，大大降低了施工事故的發生概率。

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.
