Which of the following is a situation where piking might be used?

Piking is a method typically used in utility work, particularly in the context of installing or repairing pole lines, where traditional equipment like a derrick may not be applicable. This situation arises in scenarios where space constraints or accessibility issues prevent the use of larger, more cumbersome equipment. In these cases, operators might employ piking as an alternative to maneuvering and positioning materials safely and efficiently.

Using piking in locations where a derrick cannot be brought in makes sense because it allows the workers to execute the job without relying on heavy machinery, which may be impractical in certain environments. This technique is beneficial for accessing tight or awkward spaces, ensuring that utility projects can proceed without significant delays or complications related to equipment availability.

In contrast, while dense urban environments may pose challenges that could also be addressed with piking, the primary characteristic of dense areas often involves the need for larger equipment and more complex logistical considerations, which might lead to different techniques being chosen for installation. Similarly, large diameter poles typically require more substantial machinery to manage their weight and size, making them less suited for piking. Lastly, multiple line pulls can also entail using specialized equipment that is better suited for handling such operations than piking alone, which might be more limited in its application.
