A dragline at a landfill site can be utilized for which of the following purposes?

A dragline at a landfill site is a versatile piece of heavy equipment that serves multiple functions important to landfill operations. It is particularly effective in large-scale earthmoving tasks due to its capacity to scoop, move, and place material over considerable distances.

When it comes to digging trenches, draglines are designed to excavate soil, which makes them highly efficient for creating trenches that may be necessary for drainage or utility installations within the landfill.

In terms of stockpiling cover material, a dragline can easily gather the cover material and stack it in a designated area. This capability is crucial as it enables landfills to manage their cover material effectively, ensuring that there are adequate supplies available when needed.

Additionally, the dragline can be employed to place cover material over refuse. This is a key function, as it helps to manage waste containment, control odors, and support landfill operations by promoting proper decomposition of the refuse underneath the cover.

Thus, the functionality of a dragline encompasses all of these tasks, confirming that it is indeed suitable for digging trenches, stockpiling cover material, and placing cover material over refuse. Each of these capabilities contributes to the overall efficiency and management of landfill sites.
