Which of the following is NOT a use of the HYEX?

The use of hydraulic excavators generally encompasses a variety of tasks such as digging, lifting, and moving materials, making them highly versatile machines in construction and excavation projects. Asphalt paving, while it may involve some machinery, typically requires specialized equipment such as pavers and rollers specifically designed for laying and compacting asphalt.

In contrast, tasks like haul unit loading, pipe handling, and ditching are common applications for hydraulic excavators. They are well-suited for loading materials, handling heavy pipes with their boom and bucket, and digging ditches due to their powerful hydraulic systems and articulating capabilities. Therefore, asphalt paving stands out as a function that does not align with the primary uses of hydraulic excavators, confirming that it is indeed not a standard application within the typical scope of HYEX use.
