Which of the following is NOT a part of a Handline?

The mainline is the appropriate choice for what is not a part of a handline. A handline is typically a system used for lifting or moving loads, especially in a rail or industrial setting. It consists of components that directly tie into handling equipment.

The block is a component of the handline system that serves to change the direction of force applied to a load. It is essential for creating mechanical advantage in lifting operations. The safety sling is important as it provides secure support for the load, enhancing safety during lifting.

Wire cutters, while they may be useful tools in various operations, are not specific components of a handline system; their function is unrelated to the mechanics of lifting. Since the mainline is the element that serves as the primary rope or line used in hoisting, it is not appropriate to categorize it with the other handline components. Therefore, recognizing the distinction between these components helps clarify the understanding of what constitutes a handline and its associated parts.
