Extended leads require only a two-line crane (pile & hammer) although a third auxiliary line may be used. Excellent speed, control and accuracy are possible in positioning the leads. Side-to-side as well as fore and aft adjustment is possible. A shorter boom may be used. However, extended leads require additional time to set up.
