What is considered a downside to using a compression style pulling head?

The characteristic that makes the compression style pulling head considered a downside is its sacrificial nature. This means that during the pulling process, the pulling head may become damaged or destroyed and is not intended to be reused after one or several uses. This adds an element of potential waste, as each time it is employed, a new pulling head must be used for subsequent jobs. This factor can lead to increased costs over time, particularly for frequent operations, as replacing sacrificial components repeatedly can accumulate expenses. In contrast, other aspects like weight, cost-effectiveness, or convenience may not be as pronounced an issue when factoring in the operational realities of using a compression pulling head.
