A single part line used for lifting on a crane is typically referred to as a whip line. The term "whip line" describes a lifting line that is composed of a single strand of rope or cable that can efficiently handle loads when attached to a crane. It is often characterized by its flexibility and ease of use in lifting applications, without the additional mechanical advantages provided by multiple parts of line.

Understanding the terminology is crucial for any ironworker, as it ensures clear communication on the job site and helps maintain safety standards during lifting operations. Knowing that a whip line operates without any additional blocks or pulleys allows workers to assess when it is appropriate to use such a line based on the weight and nature of the load being lifted.
