ABSTRACT:
A pile handling tool is supported at the upper end ofa tubular guide, and includes a jacking mechanism for advancing a pile longitudinally relative to the guide, and a mast projecting upwardly above the jacking mechanism and carrying an aligning structure for laterally engaging a pile and holding it in properly aligned position with respect to the guide. The mast is desirably mounted for retracting movement from an upwardly projecting active position to a laterally retracted inactive position. The jacking mechanism may be constructed to rotate one of two successive pile sections relative to the other to complete a connection therebetween.
