What factors need to be considered as part of the lift plan for wire rope?

The correct choice focuses on "weight per foot and length" as critical factors in developing a lift plan for wire rope. These two factors are essential for ensuring the safety and effectiveness of the lift operation.

Understanding the weight per foot of the wire rope helps in selecting the appropriate type and quantity of rope for the lift. This metric informs the planner about the overall mass that will be handled, allowing for adequate calculations regarding load capacities and ensuring that the lifting equipment can safely manage the total weight involved.

Additionally, the length of the wire rope is crucial because it determines how much rope is needed to reach the load and how it will be rigged. Adequate length must be available to account for all operational scenarios, including the lift's height and any potential detours in rigging.

Together, these measurements help in preventing overstressing the wire rope and ensuring that it remains within safe operational limits, ultimately contributing to a safe lifting operation.
